If you are searching inside code specifically, you may like 'ack'. It does the same thing grep does, except it has preset 'excludes', is recursive by default, and the output is a bit prettier.

Oh thanks! I will give it a whirl

It took me a moment to figure out what was going on there (with the whole clippy thing). The bulk of this list is the top commands from commandlinefu which has been on HN before [0], [1].

You can even go meta and install a command to let you search commandlinefu [2].

sudo !! Instant favorite

I often alias `sudo` to `fucking` to help vent my frustrations

    $ rm -rf somedir
    rm: somedir/: Permission denied
    $ fucking !!

Please comment if you have a favorite not on this list.

If you use tmux (or screen) you want to use byobu! https://launchpad.net/byobu https://www.google.de/search?q=byobu+tmux&tbm=isch It's a fancy statusbar that shows CPU speed, IP-address, hostname, ...

I have something similar in my .tmux.conf file

Screenshot: http://i.imgur.com/u6JY0.png

Config file: https://github.com/tylerkahn/dotfiles/blob/master/.tmux.conf...

Works with OSX and Linux.

On windows

findstr /SPINC:"some random debug message" *

Will do the same. FINDSTR is no grep, but for very simple cases like this is just fine

SPINC and SPIMC are my favorite options...

Earlier quoted context omitted.

alias lsd="ls -ltrF | grep ^d" Helps me quickly list only directories. Any better alternatives ?

Using `find` is nice to get just directories: $ find . -type d -maxdepth 1

I use:

% ls -d */

Single user mode on an HPUX machine was, I think, the most useful to me.

(http://www.unixhub.com/docs/hpux/hpux_boot.html)

I wish I still had that machine, but I do not.

Or even 'ag' (the silver searcher). Like ack, but "better". https://github.com/ggreer/the_silver_searcher

    export CDPATH=.:~/projects
    export PS1="$(uname -n)$ "
    alias ltr='ls -ltr'

More of a procedure, always list file and edit the command before deleting it:

    $ ll file.txt
    -rw-r--r--  1 zera  staff  0 Jan  7 20:28 file.txt
    Ctrl-p, Ctrl-a, Ctrl-d, Ctrl-d, r,m
    $ rm file.txt

So this is a sanity check to avoid this mistake:

    $ rm *.txt

*Edit, one more:

Ensure you overwrite a file (or aren't):

    $ cp -i ~/file.config /etc/
