make will automatically parallelize builds for the number of cores on the machine. It also breaks various things interestingly, particularly build systems which don't pay attention to correct dependences.

Strictly speaking, tmux is out of scope of the question, but I hope some people would be interested.

I found myself needing to use deeply nested tmux sessions a few times and navigating between nestings is a huge pain under a vanilla setup. Using some configuration trickery, I was able to hack in keys to "focus" between nesting levels. Here's a repo I have it sitting under:

https://github.com/xelxebar/tmux-addons/tree/master/nesting

The code should be relatively drop-in and the README not terrible.

I'd love to hear thoughts.

This is tiny, but I've gotten a surprising amount of mileage out of aliasing 'fx' to firefox --new-instance --profile $(mktemp -d) which pops open a new instance of Firefox with a completely clean, temporary profile. Super useful for testing sites or add-ons without influencing (or being influenced by) by my normal browsing profile.

I have a similar command, except it keeps the existing addons from my main profile. Which is useful as I need a proxy for different environments for work.

Please share how you did do that, that sounds awesome!

I have a bunch of project/location specific environment preparing handles in my .aliases file.

Stuff like:

alias @projectName="cd $project && alias java='/some/specific/version' && export SOME_VAR=value"

or

alias @untrustedWifi="tor && torbrowser && set up an SSH tunnel to access mail etc"

I can't really share the actual contents, because they depend on a boatload of scripts in my ~/bin dir and they're all pretty specific to my environment.

Not bash but git aliases, as a consequence of our gerrit workflow:

    alias.gerritpush=push origin HEAD:refs/for/develop
    alias.fixlast=!git commit -a --fixup=HEAD && GIT_EDITOR=true git rebase -i --autosquash HEAD~2
    alias.loglast=log -n 1 -p

Can I add something from .vimrc? If you put the commands: set undofile set undodir=~/.vim/undodir You get infinite undo in your files. Now when you go into a file, delete or add some text and close your terminal down, the next time you enter vim you can (re|un)do previous operations. Has saved my ass more times than I care to mention over my career!

This is awesome! Be sure to mkdir ~/.vim/undodir first as vim won't do it for you (or didn't for me)

I have a whole repository also including several dotfiles that I maintain for already several years [1]. Following are some snippets from the dotfiles/.alias and dotfiles/.functions files from that repository that probably are the most interesting and which I am using on a regular basis: # easier navigation alias ..="cd .." alias ...="cd ../.." alias ....="cd ../../.." alias .....="cd ../../../.." alias ~="cd ~" # Ge…

> alias .....="cd ../../../.."

How often do you use that and how often do you get it right? :-)

My cd related aliases are the following. Especially the . is surprisingly useful, although most of the time I only use .2 and .3

  alias ..='cd ../'
  alias .1='cd ../'
  alias .2='cd ../../'
  alias .3='cd ../../../'
  alias .4='cd ../../../../'
  alias .5='cd ../../../../../'
  # sometimes, the space gets swallowed
  alias cd.='cd .'
  alias cd..='cd ..'

But that gave me an idea for another useful directory changer: "go to project root".

Project root definition could vary, although nowadays it is probably "go to the first directory upstream with a .git directory"

Edit: found this elsewhere in this discussion posted by jgresty https://news.ycombinator.com/item?id=18901834

  # go to root git directory
  alias cdgit='cd $(git rev-parse --show-toplevel)'

I can't believe i never thought of using command line switches for that kind of stuff, i always just have firefox set to forget all data on close.

Not exactly a bash alias, but might be useful too: Since I often get bug reports for specific versions of firefox, i've set up a small script for downloading and starting a given firefox version: https://pastebin.com/t2PHxJqE
