/ aka - also known as /
Simple, persistent, shell-based command aliasing
Usage: aka alias show stored aliases
aka alias NAME CMD... store an alias for CMD
aka NAME [...] run CMD, optionally with more arguments
By default, aliases are stored in the `.aka` file of the current working
directory. Optionally, the location of that file can be modified by setting the
AKA_FILE enviornment variable. Tested on Debian, OpenBSD, and OpenWRT, aka uses
portable shell syntax and should work everywhere that has a typical /bin/sh
$ aka alias demo more
$ aka demo --version
more from util-linux 2.36
$ aka alias demo git
$ aka demo --version
git version 2.28.0
The command you alias can have parameters
$ aka alias l ls -f
$ aka l
.aka .. aka aka_tiny . README .git
And you can pass additional parameters
$ aka l -tR
.. aka_tiny aka .git .aka README .
You can see all of the currently stored aliases
$ aka alias
And edit them using your favorite text editor
$ cat .aka
alias l='ls -f'
Everything that is not aliased will get executed as a regular command.
$ aka python3 --version
## Why would anyone want this?
A practical use case might be to have
│ └── .aka | alias doit='make install'
│ └── .aka | alias doit='go run'
└── .aka | alias doit='pip install .'
Now you can `aka doit` to your hearts content inside each of those folders, and
have that execute the appropriate build commands for the type of project it is.
$ for x in *; do (cd $x && aka doit); done
make: *** No rule to make target 'install'. Stop.
go run: no go files listed
ERROR: Directory '.' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.
Grab aka, make it executable, and place it somewhere in your path.
## How it works
aka is a tiny portable shell script that gets executed via /bin/sh, sources
AKA_FILE and evals the positional parameters, thus applying aliases and
whatever other shell script shenanigans stored in AKA_FILE.
For example, this means that you can put something like
alias my='AKA_FILE=~/.my_aliases aka'
in your shell's startup files, and thereafter use the `my` command as an `aka`
invocation that always sources ~/.my_aliases file in your home directory,
regardless of where you run it.
Initial prototype uses aliases, which may not work for programs that depend on
establishing their behavior based on the `argv` name they were called by
(busybox, for example).
[x] AKA_FILE environment variable set to the file containing the desired
shellscript file to source. Otherwise we look for the `.aka` file in the
[ ] `aka unalias` command?
