I can't believe I didn't know about this! Thanks so much :)

I don't want to sound hyperbolic but its kind of a game changer for text editing. I understand why developers don't have it on by default in other text editors (space) but seeing as I don't fill my HDD with movies or games or any other large media like that, i've got all the space in the world.

I actually wrote 'game changer' in my original comment, and got rid of it for the same reason! Now that I've added it to my vimrc, I'm now upping it to 'life-changing'

Definitely not for everyone, but:

  set +H
  export HISTIGNORE="&"
  alias reset="printf '\033\143'"
  alias ls="ls --color=never -p -D '%Y-%m-%d %H:%M'"
  alias pmake="gmake -j30"
  PS1="\[\e[0;32m\][\w]$\[\e[m\] "
  history -w
  history -c
I turn off history substitution (sometimes ! get into my program arguments and I don't like surprises), and start with no history on new terminals. I don't trust myself not to run an rm * from a previous session, open another terminal, and hit up one too many times.

A little colorization of the terminal prompt, and spicing up of ls output (the colors actually give me trouble, and often I can't read the dark blue items at all.)

But most specifically, I adore the reset alias. Unlike clear, it isn't undone when you scroll up. The built-in reset command takes forever to run and does a bunch of things I don't want.

HISTIGNORE is my absolute favorite. It doesn't log your last command to history if it's the same as the one already there. I'll often run make multiple times to fix compilation errors, and with HISTIGNORE, the command to run the resulting binary is only ever two up keystrokes away.

To fix some bugs

    shopt -s checkwinsize
    shopt -s autocd
To make life better to my taste

    alias tmux="tmux new -A -s root"
    export HISTCONTROL=ignoredups
To distinguish between development, test and production environments by color (VERY userful)

    export PS1='[\[\e[1;91m\]\u\[\e[0m\]@\[\e[1;31m\]\H\[\e[0m\] \[\e[1;95m\]\w\[\e[0m\]]\\$ '
    export PS1='[\[\e[1;92m\]\u\[\e[0m\]@\[\e[1;32m\]\H\[\e[0m\] \[\e[1;95m\]\w\[\e[0m\]]\\$ '
    export PS1='[\[\e[1;93m\]\u\[\e[0m\]@\[\e[1;33m\]\H\[\e[0m\] \[\e[1;95m\]\w\[\e[0m\]]\\$ '

One of my most valuable aliases used is for backing up deleted files and directories using the trash-cli Linux utility.

The trash-cli utility has some quirks related to mounted drives but once you understand how to set up correctly, aliasing rm to trash can save you from losing files you've deleted by mistake.

Some of mine not already seen:

    alias mirror='wget -m -r -np -p -k -E'
    alias g_short_hash='git rev-parse --short --verify HEAD'
    alias g_head_branch='echo "`git symbolic-ref HEAD 2> /dev/null | cut -b 12-`"'
    alias g_branch_w_hash='echo "`git symbolic-ref HEAD 2> /dev/null | cut -b 12-`-`git log --pretty=format:\"%h\" -1`"'
On OS X:

    alias sleepnow="pmset sleepnow"
    alias netstat_tanp="lsof -Pnl +M -i4 -i6"

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!

Not GP, but you could just do the same except after making the temp dir: copy in `profile/addons.json` and `-r profile/extension*` from your main profile. (There might be other files needed to, not tested.)

I have many, but one above all:

I've tried several different, SimpleNote, KeepNote, EverNote... and so on. I have come to a conclusion, that using the default iOS note app is enough for me. Using paper notes while @lectures and rewriting them sometimes to Notes. I'm also using another method of note taking, which I prefer more, but which is not always accessible on the go. I stumbled upon a script here and modified it a little. (changed vim to nano and added some other):

    #! /bin/bash
    fpath=$HOME/notes.md

    if [ "$1" == "cat" ]; then
        cat "$fpath"
        exit 0
    elif [ "$1" == "rg" ]; then
        rg "$2" "$fpath"
    elif [ "$1" == "nano" ]; then
        nano "$fpath"
    elif [ "$1" == "--help" ]; then
        printf 'Commands: \n-----------------------------------------------\n
        $ notes \n
        $ notes --help\t\t--\tdisplay this help\n
        $ notes date\t\t--\tadd date row to notes\n
        $ notes \t\t--\tadd new entry \n
        $ notes cat\t\t--\tprint notes using cat\n
        $ notes rg \t--\tripgrep notes\n
        Remember to use #tags (for easier grepping)!\n\n'
    elif [ "$1" == "date" ]; then
        {
        echo ''
        echo '# '"$(date +"%m-%d-%Y-%T")"
        echo '-'
        } >> "$fpath"
    elif [ "$1" == "" ]; then
        less +G "$fpath"
    else
        {
            echo ''
            echo "$@"
            echo ''
        } >>"$fpath"
    fi
In short, writing $ notes prints out displays the notes and writing $ notes appends a new line. This is extremely powerful because of it's simplicity and easy accessibility in terminal (where I spend most of the time anyway)
