Short snippets
These short bash commands or code snippets have proven useful. I will try to collect them here, and maybe freeze some of them into a proper .bashrc
(and the relevant equivalent on Windows). Alternatively, I could bundle related snippets into blog posts. Or I finally start one of those .dotfiles
repositories. But then, I don't want to over-engineer my settings handling. Let's see where this goes.
Convert pictures to lower resolution in subfolder
Using ImageMagick (version 7), this is a handy one-liner, ready to be integrated into an only slightly longer script, moving the result to a fixed, desired output location:
Bash
mkdir export && magick mogrify -resize 3000x3000 -quality 80 -path export *.jpg
PowerShell
mkdir (get-item $PWD).Name; magick mogrify -resize 3000x3000 -quality 80 -path (get-item $PWD).Name *.jpg
Git aliases
Heavy-branching-capable lg
command. Not as commonly used ls
short (no graph) and ll
long (file stats) forms. la
is nice in that it lists all aliases. I hardly remember the d
and dc
aliases, sadly. But then, typing them out does not hurt too much.
[alias] lg = log --pretty=tformat:'%C(auto)%h %C(dim white)%cd %Creset%<(50,trunc)%s %C(bold blue)%aN%Creset%C(auto)%w(0,0,7)%+d%Creset' --decorate --graph --abbrev-commit --date=short ls = log --pretty=format:'%C(auto)%h %s %C(bold blue)%aN%C(auto)%d%Creset' --decorate ll = log --pretty=format:'%C(auto)%h %C(dim white)%cd %Creset%s %C(bold blue)%aN%C(auto)%w(0,0,7)%+d%Creset' --decorate --name-status d = diff dc = diff --cached la = "!git config -l | grep "^alias" | cut -c 7-"
