Liberate & Digitize daily works by 2 exe: File Processing, Data Mining, Map-Reduce.

Most time Just 1 command line to solve your daily text or file processing work, pipe endless.

Since 2019-07-19 a Visual Studio Code extension: vscode-msr (source code: here) to help your coding work.

Match/Search/Replace: on Windows/MinGW/Cygwin + Ubuntu/CentOS/Fedora + Darwin + FreeBSD

  • Match/Search/Replace* Lines/Blocks in Files/Pipe.
  • Filter/Load/Extract/Transform/Stats/* Lines/Blocks in Files/Pipe.
  • Execute transformed/replaced result lines as command lines.

Not-IN-latter: on Windows/MinGW/Cygwin + Ubuntu/CentOS/Fedora + Darwin + FreeBSD

  • Get Unique or Raw Exclusive/Mutual Line-Set or Key-Set;
  • Stats + Get top distribution in Files/Pipe.
  • Remove(Skip) Line-Set or Key-Set matched in latter file/pipe.

MSR Overview: Windows or Linux or MacOS

Performance Comparison: findstr + grep + msr

Windows MacOS Linux
Summary table Summary table Summary table
2X~15X+ > findstr 3X~10X+ > grep 1.5~3X+ vs 1.5~3X+

Quickly Get msr/nin + Demo + Related Resources

Almost No Learning Cost

  • Just general Regex as C++, C#, Java, Scala, needless to learn strange Regex syntax like FINDSTR, Awk, Sed etc.
  • Search: (-i = --ignore-case like: -i -t or -it or -ix)
  • Replace: (You can use both -x and -t)
    • Preview changes: msr -r -p path1,pathN -t "Regex-pattern" -o "replace-to" -j Optional-Args
    • Replace files: msr -r -p path1,pathN -t "Regex-pattern" -o "replace-to" -R Optional-Args
  • Use optional args like -P -A -C or -PAC or -PIC to get pure result as same as other tools like grep/findstr.
  • All options are optional + no order + effective meanwhile; Free with abbreviations or full-names(like -i = --ignore-case).

Usage + Examples + Color-Text-Screenshots

  • Just run msr --help or msr -h or msr (same for nin) to see usage and examples, brief quick start at the bottom of output.
  • For msr:
  • For msr + nin: Also can see tools/readme.txt
  • Zoom out following screenshots to 90% or smaller if it's not tidy or comfortable.

MSR Color Doc on Windows/Linux + Download Command

You can use a tool folder (already in %PATH% or $PATH) instead of using %SystemRoot% or /usr/bin/ (you can also link msr to there).

Validation with md5.txt use md5sum xxx like: md5sum msr* | msr -t "\s+\**" -o " " -PAC | nin md5.txt -m

NIN Color Doc on Windows/Linux + Download Command

Validation with md5.txt use md5sum xxx like: md5sum nin* | msr -t "\s+\**" -o " " -PAC | nin md5.txt -m

Demo and Test Screenshots

Zoom out following screenshots to 90% or smaller if it's not tidy or comfortable.

Powerful

  • Single exe for multiple platforms: Windows + Cygwin + WSL + Ubuntu/CentOS/Fedora/Darwin
  • Smart Loading files with 8 composable kinds of filters:
    • 5 pairs of file attribute filters:
      • File name patterns (-f/--nf)
      • Directory patterns (-d/--nd)
      • Full path patterns:
        • Regex:
          • --pp need-regex
          • --np exclude-regex
        • Texts:
          • --xp "test,mock,/obj/"
          • --sp "src/,/common/"
      • File size range:
        • --s1 1B ; --s2 1.6MB
        • --s1 file1-as-size ; --s2 file2
      • File modification time range:
        • --w1 2015-07-01T18:30:00 ; --w2 2015-08 or "2015-07-01 20:00"
        • --w1 10days ; --w2 +10d
        • --w1 file1_as_time_plus_1s_if_no_w2
        • --w1 file1_as_time ; --w2 file_or_time_or_offset
    • 3 kinds of file row / block filters to start/stop/skip reading/replacing each files/pipe:
      • Row/line number begin/end (-L, -N) like:
        • -L 30 -N 60 same with -L 30 -N +30
        • -L 30 -N 0 same with L 30 -N 30
      • Block begin/end patterns (-b, -Q) for each block in each file/pipe; with -q to stop at once for pipe/each file.
      • Normal begin/end patterns (b, -q).
  • Process pipe (output of self/other commands) endless as you want.
  • Two composable single exe: msr.exe/cygwin/gcc* especially powerful with nin.exe/cygwin/gcc*.
  • 70 composable options for msr and 30 composable options for nin (just run them without parameters to get colorful usage/examples or see readme.txt) for further extractions/mining.
     msr --help # same as running: "msr -h" or "msr"
     nin --help # same as running: "nin -h" or "nin"
     msr | msr -t "^\s*-{1,2}\S+" -q "^\s*-h\s+" --nt "--help"
     nin | msr -t "^\s*-{1,2}\S+" -q "^\s*-h\s+" --nt "--help"

One Limitation

  • Cannot process Unicode files/pipe so far; Fine with UTF-8 and ANSI etc.

Just Run the EXE to Get Color Usage and Examples

Besides the doc here and test scripts, some script/batch/shell files are also examples in this and sub-folders.

Brief Summary of msr EXE

Use the rich searching options of like below, combine these optional options (You Can Use All):

  • Set searching paths: (Can use both)
    • Recursively(-r) search one or more files or directories, like: -r -p file1,folder2,file2,folder3,folderN
    • Read paths (path list) from files, like: -w path-list-1.txt,path-list-2.txt
  • Set max search depth (begin from input folder), like: -k 16 (default max search depth = 33).
  • Filter text by line-matching (default) or whole-file-text-matching (add -S / --single-line Regex mode):
    • Ignore case for text matching:
      • Add -i (--ignore-case)
    • Regex patterns:
      • -t should-match-Regex-pattern
      • --nt should-not-match-Regex-pattern
    • Plain text:
      • -x should-contain-plain-text
      • --nx should-not-contain-plain-text
  • Single-line-Regex mode (-S) for Regex "^"and "$":
    • Treat each file as one single line. If reading pipe, treat whole output as one line.
    • If block matching (used -b + -Q): Treat each block as one line in a file. Useful like removing a whole block.
  • Filter file name: -f should-match-Regex , --nf should-not-match-Regex
  • Filter directory name: -d at-least-one-match-Regex , --nd none-should-match-Regex
  • Filter full path pattern: --pp should-match-Regex , --np should-not-match-Regex
  • Filter full or sub paths: --xp "d:\win\dir,my\sub,\bin\,\out\\" , --sp "\src\,common"
    • Newer msr support universal slash / for --pp/--np + --sp/--xp like:
      • --xp "d:/win/dir,my/sub,/bin/,/out/"
      • Check if support universal slash by command: msr --help | msr -x "Support '/' on Windows"
  • Skip/Exclude link files: --xf
  • Skip/Exclude link folders: --xd
  • Try to read once for link files: -G (link files' folders must be or under input root paths of -p or/and -w)
  • Filter file size: --s1 <= size <= s2 , like set one or two: --s1 1B --s2 1.5MB
  • Filter file time: like --w1 2015-07, --w2 "2015-07-16 13:20" or 2015-07-16T13:20:01 (quote it if has spaces).
  • Filter rows by begin + end row numbers: like -L 10 -N 200 (for each file).
  • Filter rows by begin + end Regex: like -b "^\s*public.*?class" -q "^\s*\}\s*$"
  • Filter rows by 1 or more blocks: -b "^\s*public.*?class" -Q "^\s*\}\s*$"
  • Filter rows by 1 or more blocks + stop like: -b "^\s*public.*?class" -Q "^\s*\}\s*$" -q "stop-matching-regex"
  • Quickly pick up head{N} results + Jump out(-J), like: -H 30 -J or -J -H 300 or -JH 300 etc.
  • Don't color matched text: -C (Faster to output, and must be set for Linux/Cygwin to further process).
  • Output summary info to stderr + hide warnings in stderr (like BOM encoding): -I : Like -I -C or -IC or -J -I -C or -JIC etc.
  • Use --force to force replace BOM files which header != 0xEFBBBF (if UTF8 encoding is acceptable).
  • Use --keep-color on Windows/MinGW if you want to keep color for pipe or output file.
  • Use --colors to change/set colors for match-result / file-paths / final summary: See Set-Or-Change-Color-Groups.
  • Use --unix-slash 1 to output forward slash (/) of file paths on Windows (msr/nin accepts 2 types of slash: '/' and '\').
  • Use --exit number/Math/Regex to change exit code, like:
    • Use --exit gt255-to-255 for Cygwin/Linux/MacOS shell.
    • Use --exit gt127-to-127 for MinGW on Windows.
    • It's not recommended to set global MSR_XXX environments in your machine, because this may cause errors for other people/machines.
      • You can set environment temporarily(like vscode-msr) in a command line or in a script header like:
        • export MSR_EXIT=gt0-to-0,le0-to-1 (this will change to traditional return value style).
        • This is safe (only impact 1 script) + Convenient yourself if you're used to traditional usage.

Scenario Glance

  • Search code or log:

    • msr -rp folder1,folder2,file1,fileN -t "Regex-Pattern" -x "And-Plain-text" --nt ... --nx ... --nd ... -d ... --pp ... --np ... --xp ...

  • Search files + Extract + Transform to target text/value:

    • msr -rp folder1,folder2,file1,fileN -t "Regex-Pattern" -o "Replace-To" + Optional Args

  • Get matched file list (You can omit -o xxx). You can also append | msr -t "(.+)" -o "command \1" -X to process files.

    • msr -rp folder1,folder2,file1,fileN -t "Regex-Pattern" -o "Replace-To" -l + Optional Args

  • Replace text:

    • msr -rp folder1,folder2,file1,fileN -t "Regex-Pattern" -o "Replace-To" + Optional Args

  • Just preview changed files + lines:

    • msr -rp folder1,folder2,file1,fileN -t "Regex-Pattern" -o "Replace-To" -j + Optional Args

  • Replace files (-R) and backup (Add -K):

    • msr -rp folder1,folder2,file1,fileN -t "Regex-Pattern" -o "Replace-To" -R + Optional Args

  • Insert or add a line with same indention:

    • msr -rp paths -f "\.(xml|json)$" -it "^(\s*)(regex-groups)" -o "\1\2\n\1{add-your-line}" -R

  • Replace or remove specific matched block (multiple lines) like code files and config files(XML/JSON/YAML/INI etc.):

    • msr -rp paths -f "\.xml$" -b "^\s*</Tag1>" -Q "^\s*</Tag1>" -it "match-regex" -o "replace-to or empty/to-remove" -R with -S if you need.

  • Sort log files by time text (auto set to previous line's time if a line no time) + Get error top distribution:

    • msr -rp paths -F "\d{4}-\d{2}-\d{2}\D\d+:\d+:\d+[\.,]?\d*" | nin nul "\.(\w+Exception)\b" -p -d -O -w

  • Grep numbers in files or pipe, and sort (-s) as number (-n) + Show stats: Count + Sum + Max + Min + Median + Average + Standard-Deviation + Percentiles etc. :

    • msr -rp paths -f "\.log$" -t "time cost = (\d+\.?\d*)" -n -s ""
    • xxx-cmd-output | msr -t "(match-1), value = (-?\d+\.?\d*) -n -s "value = (-?\d+\.?\d*)"

  • Further processing based on summary (generate text, or command lines with -X to execute):

    • msr -rp paths -it regex -x text --nt skip-regex --nx skip-text -H 0 -c key message | msr -t "^Matched (\d+) .*? -c (key message)" -o "replace to text or command line" -X

Tip for Captured Groups Reference to Replace Files or Transform Text

It's better to use "\1" than "$1" which let you easier to copy/migrate your replacing command lines.

  • For example: msr -p paths -i -t ".*?text = (capture1).*?(capture2).*" -o "\1 \2"
    • "\1" = "$1" for CMD console or batch files (*.bat or *.cmd) on Windows.
    • "\1" = '$1' for PowerShell (Windows / Linux) or Bash (Linux / Cygwin).

Tips for Frequent Usages

  • Execute output lines as command lines:
    • Often use -X -M (or -XM) to hide final summary of executions.
    • Use -X -I to avoid show each command's return value + time cost + command line.
    • Use -X -P -I or -X -A to hide all.
    • Run a command, exit if return != 0: echo command line | msr -XM || exit -1 (use exit /b -1 on Windows CMD)
    • Directly run a simple command line: msr -XM -z "command line" || exit -1 (use exit /b -1 on Windows CMD).
    • Set UTF-8 no-BOM encoding if matching head failed due to encoding changed by Python/PowerShell/etc, like:
      • [Console]::InputEncoding = New-Object System.Text.UTF8Encoding $false
      • file/pipe/command output | msr -t "^head-search-Regex" -o "replace-to" ...
    • You don't need to change encoding if execute(-X) output, msr will auto detect and trim the BOM header before executing:
      • file/pipe/command output | msr -X
      • file/pipe/command output | msr -t "search-Regex" -o "replace-to" ... -X
  • Replace Files(-R):
    • Use -j to preview changes before replacing(-R).
    • Use -M -T 0 to hide summary + final changed file list, only output immediate change info (hide by -H 0).

  *** ***
  More detail/examples see the home doc or just run the exe with '--help' or '-h' or no args.

Set or Change Color Groups

  • Method-1: Use --colors to set color groups for matching text + file paths + summary.
    • Full color groups example (explanations see below):
      • --colors "Green, t=Red+Blue_Yellow+Magenta_Red, x=Yellow, e=Cyan, d=Blue, f=Green, m=Green, u=Yellow"
      • Valid color names(no-case): Red + Green + Yellow + Blue + Cyan + Magenta + Black + White + None.
  • Method-2: Set environment variable MSR_COLORS with value of --colors example above.

Group-1 of Colors for Matching Text

Default Colors of Text Matching
  • Plain text matching(-x) use Yellow(Yellow_None):
    • Foreground Color = Yellow
    • Background Color = None(usually Black).
  • Regex text matching(-t) use color arrays for Regex-captured-groups:
    • Linux = Red_Black + Yellow_Red + White_Magenta + Cyan_Red
    • Windows = Red_Black + White_Red + Red_Yellow + White_Magenta
  • Regex enhance/extra-coloring (-e):
    • Windows = Green_Black + White_Blue + Black_Cyan + Magenta_Black + Black_White + Yellow_Black
    • Linux = Green_Black + White_Blue + Yellow_Blue + Magenta_Black + Black_White + Yellow_Black
  • Example:
    • Command:
      • echo abc 123 extra plain | msr -t "\w+ (\d+)" -e "ext\w+" -x plain
    • Group -t matched result:
      • Output abc with color Red_Black: foreground = Red, background = Black.
      • Output 123 with color White_Red.
    • Group -e matched result:
      • Output extra with color Green_Black.
    • Group -x matched result:
      • Output plain with color Yellow.
Change Default Matching Colors
  • Change all colors with no group name of x/t/e:
    • Example command: echo abc 123 extra plain | msr -t "\w+ (\d+)" -e "ext\w+" -x plain --colors Green
    • All matched text of groups -t/-x/-e will be output with Green color.
  • Change one group with group name of x/t/e:
    • Example command: echo abc 123 extra plain | msr -t "\w+ (\d+)" -e "ext\w+" -x plain --colors Green,t=Cyan+Red_Blue
    • Group -t result use Cyan + Red_Blue
      • Output abc with Cyan.
      • Output 123 with Red_Blue
    • Other matched result of -x/-e use Green color.
  • Remove one or more group color:
    • Example command: echo abc 123 extra plain | msr -t "\w+ (\d+)" -e "ext\w+" -x plain --colors t=none
    • Group -t result will be no color, other groups (-x/e) keep colors.

Group-2 of Color for Result File Path

  • Change result file path color with d/f/p for directory/file-name or path for both.
    • Example command: msr -p . -l --colors p=green_blue
    • Output file paths with color = Green_Blue (foreground = Green, background = Blue).
  • Remove colors for file paths:
    • Example command: msr -p . -l --colors p=none
    • Output file paths with color = None which is no color.

Group-3 of Color for Final Summary Text

  • Change summary color if matched (usually found results):
    • Example command: msr -p . -f "\.cpp$" -t search -x plain-text --colors m=Green.
  • Remove summary color whatever matched(m) or not(u):
    • Example command: msr -p . -f "\.cpp$" -t search -x plain-text --colors m=none,u=none.

If you Want to Use MSR to Color Execution

General example: Transform output to command lines then execute:

echo command line or command output lines | msr -t Search-Regex -o Replace-To -X -P -I -M -A ...

  • Hide commands before execution: -P like -X -P or -XP
  • Hide return value and time cost: -I like -X -I or -XI
  • Hide summary of all executions: -M like -X -M or -XM (-XM or -XMI is mostly used)
  • Hide all(command/cost/summary): -A like -XA
  • Output "return-value+command" only if a command returns abnormal code (fail):
    • Use -X -O to output "return-value+command" only if a command return != 0.
    • Use -X -O -V xxx like -V gt0 to output only if return value > 0.

If you Want to Use MSR to Color Output

Brief introduction besides the color doc msr-Color-Doc on Windows as following:

Related controls and options that you can use at the same time:

  • Color Options

    • -x Plain-Text : Set Yellow color to matched Plain-Text
    • -t Regex-Pattern: Set Red color to matched Regex group[0], different group[N] different color.
    • -e Regex-Pattern: Set Green color to matched Regex group[0], different group[N] different color.
      • Difference: -e just add colors, -t will add colors + only show matched lines if not used -a.

  • Auxiliary Controls

    • -P: Hide path/line/row.
    • -M: Hide summary message.
    • -A: No any other info/text. Almost same to combination of -P -M
    • -I: Output summary to stderr.
    • -a: Show all output lines/text including not matched.

  • Frequently Used Examples

    • Only show captured text with color:
      • echo cmd output text | msr -PA -t "Regex, error or need Red color"
      • echo cmd output text | msr -PA -x "Plain text, warning or need Yellow color"
    • Show all output: Add color to specific text:
      • echo cmd output text | msr -aPA -t "Regex, error or need Red color.*?(group1) (group2)" -e "extra color (group1) (groupN)"
      • echo cmd output text | msr -aPA -x "Plain text, warning or need Yellow color" -e "extra color (group1) (groupN)"
    • More complicate coloring:
      • echo cmd output text | msr -aPA -it "Regex (group1) (group2)" -e "extra (color) (group)" -x "plain text"
      • echo cmd output text | msr -PA -it "Regex to only show matched" --nx "exclude text" --nt "exclude Regex"
      • echo cmd output text | msr -PA -it "Regex to only show matched with up/down rows, head 100, tail 100" -U 3 -D 9 -H 100 -T 100
