My favorite new one that I have been using a lot: function cheat() { curl cht.sh/$1 } It queries the cht.sh cheatsheet of various Unix commands. 'cheat tar' prints: # To extract an uncompressed archive: tar -xvf /path/to/foo.tar # To create an uncompressed archive: tar -cvf /path/to/foo.tar /path/to/foo/ # To extract a .gz archive: tar -xzvf /path/to/foo.tgz # To create a .gz archive: tar -czvf /path/to/foo.tgz /path…

This is awesome, I ALWAYS have to google for how to untar an archive (I don't do it often enough to commit to memory) thank you!

I have an alias "x" setup to run:

      atool --extract $*
That will unpack "anything", into a sub-directory if necessary. Something I use more than any other alias.

One thing I do is to put this snippet in .bashrc or .profile for i in ${HOME}/.bash.d/*.sh do if [ -r ${i} ] ; then . ${i} fi done And drop some custom scripts in ${HOME}/.bash.d/ like alias.sh, env.sh (my common .bash.d scripts are saved in a git repository)

Whoa, I know someone who does exactly this. Is this a common pattern? Unless you're him!

I do that in my dotfiles too:

The main include:

The actual dotfiles:

Here's a function you can use to generate a strong printable password on the fly: function gen_passwd () { openssl rand 150 |\ tr -dc '[:graph:]' |\ cut -c 1-${1:-13} } The default password length is 13 characters but you can pass a different length parameter instead. Explanation: * generate 150 pseudo-random bytes using openssl's rand * discard non-printable characters * cut to desired length Note that it will only…

I'm trying to use this in mac shell, but it says `tr: Illegal byte sequence`

Try setting LC_CTYPE:

  env LC_CTYPE=C tr ..

These are probably the 3 I find most useful:

Copies the directory of the current git dir into the clipboard.

    which pbcopy &> /dev/null
    if [[ $? -eq 0 ]]; then
        CLIPBOARD_COMMAND="pbcopy"
    fi
    which clip &> /dev/null
    if [[ $? -eq 0 ]]; then
        CLIPBOARD_COMMAND="clip"
    fi

    cpgitdir() {
        GIT_DIR=`git remote show -n origin | grep "Fetch URL" | sed -e "s/  Fetch URL: //"  | tr -d '\n'`
        echo "Copying git dir to clipboard: $GIT_DIR"
        echo $GIT_DIR | tr -d '\n' | $CLIPBOARD_COMMAND
    }
Allows you to split your .bash_profile into multiple .bash_profile files for clarity

    if [[ -d ~/.bash_profile.d ]]; then
        for file in `find ~/.bash_profile.d -type f`; do
            source $file
        done
    fi
Simple calculator

    calc () {
        bc -l

Earlier quoted context omitted.

In my previous setup, I had a function that displayed a menu when I started bash, listing all my "main" directories. So each time you started a session you just had to press 1-7 to go where you wanted.

That is a great idea. Thank you!

Definitely save me some time and effort. The only issue I had was that sometimes when I wanted to use bash from, like, another app it would start the menu so it wouldn't work to use it from them. I'm sure it can be worked around but it was never a real issue so I didn't work on it.

Here is the code I had https://gist.github.com/jontelang/c6317bf14c527d2a89f1efd5d0... and I put this straight into my .bash_profile and it runs automatically when the shell starts.

Something funny: alias crontab='fuck you, ' Background: Everyone knows that in a [in]sane workplace, you ALWAYS have to lock your machine. So this particular new hire forgot to lock her machine and one of the seniors (senior prankster, I would say) jumped into her terminal and set a crontab to run EVERY MINUTE.

should be:

Love this thread! Some of mine (excluding similar to what has already been mentioned):

  alias mkdir="mkdir -pv"
  alias ssh="ssh @"
  alias clearmail='sudo rm /var/mail/'
  alias flushcache='dscacheutil -flushcache && sudo killall -HUP mDNSResponder'

SSH has a configuration file (.ssh/config) which lets you set configuration for specific hosts and even aliases:

    Host reproserver
    User remi
    Hostname 128.122.217.96
    IdentityFile ~/.ssh/id_rpz
