Usage

... | min_vals [options]

Options

[-?          | --help]               #  Print full usage description.
[-x          | --no_stream]          #  Do not emit records.
[-o <file>   | --data_out=<file>]    #  Write result to file.
[-k <list>   | --keys=<list>]        #  Comma separated list of keys.
[-l <string> | --list=<string>]      #  Key with ; separated values to calculate min from.
[-I <file!>  | --stream_in=<file!>]  #  Read input from stream file  -  Default=STDIN
[-O <file>   | --stream_out=<file>]  #  Write output to stream file  -  Default=STDOUT
[-v          | --verbose]            #  Verbose output.

Examples

Consider the following table in the file test.tab:

Human   123     78      0;1;2;3;4;5
Dog     45      81      6;7;8
Mouse   6       5       9

To find the minimum value in the second column, read in the table with read_tab and then pipe to min_vals:

read_tab -i test.tab | min_vals -k V1 -x

REC_TYPE: MIN
V1_MIN: 6
---

To get the minimum value from two columns:

read_tab -i test.tab | min_vals -k V1,V2 -x

REC_TYPE: MIN
V1_MIN: 6
V2_MIN: 5
---

To get the minimum value from a ; separeted list of values use the -l switch:

read_tab -i test.tab | min_vals -l V3      
V3: 0;1;2;3;4;5
V0: Human
V2: 78
V1: 123
V3_MIN: 0.00
---
V3: 6;7;8
V0: Dog
V2: 81
V1: 45
V3_MIN: 6.00
---
V3: 9
V0: Mouse
V2: 5
V1: 6
V3_MIN: 9.00
---
