command line aliases to make repeated processes quicker. I’ve used them in the past and on specific programs but never on command line utilities.
like for instance with Debian, I’m repeatedly typing sudo apt-get install, so I aliased it: alias sagi=“sudo apt-get install” and it works pretty good.
Are there any best practices or aliases to avoid when using them? Other than known commands obviously. Are there popular alias lists out there?
alias more=“less -cX”
alias moer=more
alias meor=more
alias meor=more
alias mroe=more
alias More=more
alias grpe=grep
alias gerp=grep
alias gpre=grep
In a big fan of the ‘fuck’ package for this. Try it out. Sudo apt install thefuck.
edit: oops got the name wrong; been a while since I installed it. Fuck.
Funny. I never even thought of using thefuck in any remotely production-esque kind of way. Only for its intended use case: to save me a few keystrokes retyping some command I fucked up typing.
A humble and simple “c” for “clear” in the terminal.
For a few basic things, yes. For a couple of others, I’ve set up a shell function or a script instead.
Obligatory warning before I list a few of my aliases - overriding commands by an alias with the same name can be dangerous, as it can mean that expected behaviour can become destructive behaviour on a foreign system without those aliases. e.g. a common error is aliasing rm
to rm -i
so that rm
always asks if the user is sure. Until that user is on a different machine without the alias and the files vanish without warning, anyway. Oops.
Some of mine are arguably questionable in that regard, but I don’t think any will result in anything particularly destructive if I expect them in the wrong place.
These two override the default which
command to deliver slightly more useful output, especially when the command is itself an alias (or an alias override). command
is a bash builtin:
alias Which='command -V'
alias which='command -v'
The obligatory ls
config override. long-iso
formatting ensures that ls
’s output is consistent, which is tidy, and also useful for further processing. That said, use of stat
is probably a better choice for that sort of thing.). LC_ALL=C
setting is so that things sort in “ASCIIbetical” order. My locale mixes upper and lowercase filenames and I’m too old-school for that sort of thing.:
alias ls='LC_ALL=C ls --color=auto --group-directories-first --time-style=long-iso'
Some versions of mtr
start in GUI mode. -t
prevents that. And of course, Windows muscle memory dies hard:
alias mtr='mtr -t'
alias tracert='echo '\''Use mtr, you ninny.'\'''
Hex dump using the ancient and nearly always present od
command (the incantation is right out of the od
manual):
alias odx='od -A x -t x1z -v'
Process control. Give either a PID and the process will do as it’s told. Usually. :
alias pause='kill -TSTP'
alias resume='kill -CONT'
How many times do I type the wrong thing? Too many:
alias quit='exit'
Setup for fortune
. The first one is self-explanatory. The second one shows which of the fortune files the fortune came from (-c
) but does some shenanigans to send that header to STDERR rather than STDOUT. This makes the header vanish when fortune
is piped into fun things like cowsay
.
alias bofh='fortune bofh-excuses'
alias fortune='fortune -c | while read -r line ; do [[ ! "$A" ]] && echo $line >&2 || echo $line ; [[ "$line" == "%" ]] && A=1; done'
I have a load of silly text cipher filters as scripts, but this one came for free with the bsdgames package
alias rot='caesar'
alias rot13='caesar 13'
And of course, every time I create a new alias (which isn’t very often, I admit), I run this one, which dumps all current aliases into a file that some distros set up by default.
alias save_aliases='alias > ~/.bash_aliases'
Certain aliases related to docker compose, just because it saves 2-3 words which never change.
There’s not enough storage space on the Internet to list all my aliases.
