Shome shell junk. Thish'sh for myshelf, becaushe I can't remember shi~, and thish, shomeday, may shave me a couple of hoursh...

Someday I'll write a Makefile for doing all this cumbersome work, but for now...

• zsh, though good old bash with .bash_profile will do.
• The coreutils package installed on macOS (brew install coreutils).
• This repository cloned as .sh-files to ~:

$ cd ~ && git clone https://github.com/arcdelta/.sh-files.git

You can either copy-paste the code below into your .zshrc:

# Sh-files injection
export SHFILES="$HOME/.sh-files"

source "$SHFILES/loader.sh"
include $SHFILES/rc \*

or echo it there directly from shell:

$ echo '# Sh-files injection
export SHFILES="$HOME/.sh-files"

source "$SHFILES/loader.sh"
include $SHFILES/rc \*' >> ~/.zshrc

Note. If you're not sure what one or another alias stands for, you can simply use which <aliases>.

$ which gcm gai
gai: aliased to git add --interactive
gcm: aliased to git commit -m

For convenient usage it's advised to place them inside /usr/local/bin, $HOME/bin or $HOME/.local/bin. There's no consensus on this topic, but I'm personally leaning towards the last option. Anyway, don't forget to add the directory of your choice to the PATH environment variable (if it's not there already).

Let's say you decided to go with the $HOME/.local/bin option. Check if $HOME/.local/bin is already in the PATH:

$ echo $PATH | grep $HOME/.local/bin

If a string with $HOME/.local/bin in it is returned, then you're good to go and can either create a symlink to a binary, or manually put it into $HOME/.local/bin.

If nothing is returned, you can add $HOME/.local/bin into your .zshrc like that:

$ printf '\n# PATH\nexport PATH="$HOME/.local/bin:$PATH"\n' >> ~/.zshrc

or use the default editor (if it's not set, it'll fallback to vi):

$ "${EDITOR:-vi}" ~/.zshrc

or, if you're a wuss, just use vscode:

$ code ~/.zshrc

Then, hold yourself firmly in the .sh-files directory:

$ pwd
/Users/vm/.sh-files

Create a symlink:

$ ln -s `pwd`/bin/cm $HOME/.local/bin/fake-the-date

Make it executable, then source the config or reopen terminal:

$ chmod +x $HOME/.local/bin/fake-the-date
$ source ~/.zshrc

Test it:

$ fake-the-date
cm: You should specify the commit message and (optionally) the date

Usage: cm [message] [[date]]

Examples:
$ cm 'Plant a tree' '2 days ago'
$ cm 'Create yet another framework' '1 hour ago'
$ cm 'Raise a kid' '2019-11-11 12:35:18'
