scripts

overview

A collection of personal scripts I use.

I use most of these scripts for convenience and to save on typing.

More recently I've been making an effort to learn PowerShell as I tend to use windows a fair bit too, so there are a few one-off scripts used for that too.

• nix/ - Scripts for POSIX (Unix, MacOS, Linux, etc) machines. Mostly written in sh and bash.
• win/ - Scripts for Windows. Using PowerShell
• any/ - Scripts for multiple environments (mostly Python).

install

POSIX (Linux, Mac, BSD)

I've created an install script (bash).

usage: ./install [ARGUMENTS] [SCRIPT]

SCRIPTS
  Optionally, you can specify a script to install.
  Any specified scripts must be the filepath to the
  script (not just the filename).

ARGUMENTS
  -f, --force         overwrites files when installing
  -r,   --reinstall   re-install scripts already existing in
              destination directory
  -d, --dest [DEST]   set the install destination
  -a, --all           install ALL the scripts ('y' to all prompts)
  -l, --link          'ln' the script (not cp).
  -h, --help          print this dialog

Windows

I haven't got a script for Windows since there aren't enough scripts to justify the effort (yet).

What I usually do is just put the scripts in a directory and add it to the PATH environment variable.

scripts

Powershell

• random - a script I use to select a random item in a directory.
• zipto7z - converts all .zip files in current directory to .7z.
• flac2mp3 - convert flac files to mp3 files using ffmpeg.

Python

• d2h - convert decimal numbers to hexadecimal.
• h2d - convert hexadecimal numbers to decimal.
• jiggle - move the mouse 1px every minute - keep the screen awake.

Shell/Bash

I make an effort to keep to sh when I can, for compatibility-sake.

strings & numbers

Scripts related to string parsing/manipulation

• strindex - print the index (from 0..n) of the first character in substring $1 found in string $2.
• grepf - find all files in dir $1, that conatin string $2. I use this one a lot.
• randstr - generate a random string.

file management

• backup - cp input files $@ from filename to filename.bak (mv with -m).
• catrm - rm -i but with the option to cat the file.
• flac2mp3 - converts .flac files $@ to .mp3. Requires ffmpeg.
• openurl - xdg-open all links found in files $@.
• mkdcp - make directory $1 and copy files into it ($2..$n).
• mkdmv - make directory $1 and move files into it ($2..$n)
• mkdnvim - make directory $1, touch file $2 and open file $2 in $EDITOR.
• mkdtouch - make a directory $1, touch files in it ($2..$n).

tooling

• pyserve - shorthand for python3 -m http.server --directory $1.
• git-cfg - shorthand for calling git config --local user.name $1 && git config --local user.email $2.
  • You can also use it for setting global config using -g
• git-clone-bulk - clone a list of git repositories.
• git-pull-all - pull all remote git branches from the current upstream.
• git-pradd - git diff $@, for each prompt y/n whether to git add it
• gobuild - build a go module in all available output formats, useful for releases.
• preview-md - convert a markdown file $1 to html, open if $2 == "-o" or "--open".
  • Uses cmark by default, set conversion tool and default output destination in src.
• compress-pdf - compress a .pdf file ($1), requires ghostscript (gs).
• rled - invoke ed with a readline wrapper (for input history)
• gnome-shell-cycle-wallpaper - One I used to cycle the wallpaper on a GNOME desktop infrequently

misc

• shush - run $@ in the background and hide output.
• pomodoro - a pomodoro timer.
• while-true - clear the terminal, run $1 sleep ($2 || 1 sec), repeat forever (Ctrl+C to cancel).
• onfilech - stat a file ($1) every 10 seconds, if the output changes, run a command ($2...$n).
• awkcol - column with awk (at one point column wasn't available but awk was)

depreciated

This contains scripts that I once used but aren't required anymore (or I eventually realised were useless).
