Utilities

This repository contains some utility scripts which I found useful in my workflow.

The scripts are tested and used on Linux; they might or might not work on other operating systems.

They can be run directly from the location where the repository is checked out. For convenience, there is also a Makefile which provides an install target. To install the scripts on your machine, simply call make install in the repository root.

focus-or-start

Utility to either focus a program on an x-window system if it is already started, or start it otherwise.

If the program is started by the script, it runs in the background to have a similar experience to the case when the program is not started.

Dependencies

The script depends on wmctrl, which need to be installed on the target system.

Usage

focus-or-start PROGRAM [ARGS...]

where

• PROGRAM is the path of the program to start
• ARGS are possible arguments to the program. They will only be evaluated if the program is started by focus-or-start; if the program is already running, they will be ignored.

resize-images

Batch script to resize images in a directory. Puts the resized images into a sub directory.

Usage

resize-images [-S SOURCE] [-T TARGET] [-f FILE] [-s SIZE] [-h]

where

• -S SOURCE Specifies the source folder to read from. Default is the current directory.
• -T TARGET Specifies the target directory. Default is Publish
• -f FILE Specifies a file to process. If not given, <TARGET>.txt (from the target name, see above) is used if it exists; if this file does not exist, resize.txt is used. If resize.txt file does not exist either, then all files matching *.JPG or *.jpg are processed.
• -f Prints this help text and exits.
• -s SIZE Resizes the images to the specified size. SIZE must be in the form <WIDTH>x<HEIGHT>. Default is 2048x1536.

Dependencies

To resize the images, the convert command of imagemagick is used.
