Make common administration tasks go through sudo without having to type sudo:

alias dpkg="sudo dpkg"
alias apt-get="sudo apt-get"
alias modprobe="sudo modprobe"

Serve files from CWD via a webserver:

alias serve="python2.5 -m SimpleHTTPServer"

Color stuff; grep w/ less that doesn't mess it up

alias ls="ls --color=auto -F"
alias grep="grep --color=auto"
alias less="less -R"

open up files in existing vim session

alias rvim="gvim --remote" Thu, 10 Jul 2008 16:48:00 GMT donotreply@osnews.com (jonas) Comments http://osnews.com/thread?322357 http://osnews.com/thread?322357 I don't agree with the rm -i alias. I've gotten into the habit of explicitly using mv -i and rm -i (when using wildcards). If a user assumes rm will provide interactive feedback - i.e. because it's aliased that way on a couple systems - s/he may be very surprised when working on a system that does not. Thu, 10 Jul 2008 16:54:00 GMT donotreply@osnews.com (anomie) Comments http://osnews.com/thread?322358 http://osnews.com/thread?322358 Instead of ssh aliases, I edit ~/.ssh/config to something similar:
host NAME
Hostname IPADDRESS
Port PORT
RemoteForward REMOTEPORT localhost:LOCALPORT
and then just "ssh NAME"

And here are my most important aliases:
fichiers=/home/me/files
alias cdh='cd $fichiers'
alias cdt='cd $fichiers/downloads'
[...]

alias burn_dvd_iso='growisofs -speed=2 -dvd-compat -Z /dev/dvdrw='
alias nano='nano -w'
alias screen="screen -U"
alias df="df -h --print-type"
alias du="du -h --max-depth=1 ."
alias free='free -m'
alias grpe='grep'
alias top="htop"
alias untar="tar -xvf"

# Find process
alias pss="ps aux | grep -i"

alias dc='cd'
alias sl='ls'
alias sls='ls'
alias l='ls'
alias rm='rm -i'
lsbase='/bin/ls -h --group-directories-first --color=auto'
alias ls="$lsbase -gG"
alias lsg="$lsbase -l"
alias la="$lsbase -la"

alias su='sudo -i'
alias shutdown="sudo shutdown"
alias halt="sudo halt"
alias nanos='sudo nano'
alias snano='sudo nano'
alias svim='sudo vim'
alias cpufreq-set='sudo cpufreq-set'

And now functions, instead of alias. Allows you to give arguments:
# Diff svn workdir to head with kompare:
sdiff() {
svn diff $1 | kompare -o -
}

I can't live without these Edited 2008-07-10 16:59 UTC Thu, 10 Jul 2008 16:56:00 GMT donotreply@osnews.com (big_gie) Comments http://osnews.com/thread?322359 http://osnews.com/thread?322359 yeah that's true. But this is slower to type... and CLI is all about speed!
I remember someone suggesting a different alias for "rm -i" like rmi... Thu, 10 Jul 2008 16:58:00 GMT donotreply@osnews.com (big_gie) Comments http://osnews.com/thread?322365 http://osnews.com/thread?322365 I have a lot of aliases to cd to specific directions. I also have:

# Can't even remember what it all does. N is probably line numbers
alias less='less -x4 -R -N'

# Needs 256color support in the terminal
PSCOLOR="214" # or another color, each server i use has a different color
export PS1="\033[38;5;${PSCOLOR}m\h\033[38;5;231m:\033[38;5;${PSCOLOR}m\w\n\0 33[38;5;231m#\033[0m "

I also have a bunch on my .vimrc as well.. Thu, 10 Jul 2008 17:45:00 GMT donotreply@osnews.com (sappyvcv) Comments http://osnews.com/thread?322367 http://osnews.com/thread?322367 Nice tips, but i prefer to put them in my ~/.inputrc (linked to a function key)

sample:
~# grep apt .inputrc
"\e[17~": "aptitude update && aptitude safe-upgrade\n" Thu, 10 Jul 2008 17:56:00 GMT donotreply@osnews.com (cobbaut) Comments http://osnews.com/thread?322370 http://osnews.com/thread?322370 Here's an alias for you...

List only directories:
alias lsd="ls -d */"

take back to previous directory (cd - takes you to the previous directory):

alias p="cd -" Thu, 10 Jul 2008 18:33:00 GMT donotreply@osnews.com (amjith) Comments http://osnews.com/thread?322383 http://osnews.com/thread?322383 alias remove_crap_article="find ~/ -type f -exec perl -p -i -e 's/http:\/\/blogs.techrepublic.com.com\/10things\/\?p=352\&tag=rbx ccnbtr1//' {} \;"


Use this every time you mistakingly visit that article. Thu, 10 Jul 2008 19:16:00 GMT donotreply@osnews.com (libray) Comments http://osnews.com/thread?322390 http://osnews.com/thread?322390 rofl to death !
the best thing I read today man !
can't stop laughing !!

_THANK_YOU_! Thu, 10 Jul 2008 20:14:00 GMT donotreply@osnews.com (gnemmi) Comments http://osnews.com/thread?322426 http://osnews.com/thread?322426 Here are some nice aliases for use with FreeBSD.

The obvious ls:
alias ls 'ls -FG'
alias ll 'ls -laFG'
setenv LSCOLORS ExGxdxdxCxDxDxBxBxegeg

Playing with the floppy disk:
alias flop 'tar cvjf /dev/fd0'
alias unflop 'tar xvjf /dev/fd0'

Creating CDs:
alias burndata 'cdrecord -v -eject -tao -data'
alias burnaudio 'cdrecord -v -eject -dao -audio'

Unmounting and ejecting (inconsequent implementation):
alias ucd 'umount /media/cdrom && cdcontrol eject'
alias udvd 'umount /media/dvd && cdcontrol eject'
alias uwr 'umount /media/writer && cdcontrol -f /dev/acd1 eject'
alias ujaz 'umount /media/jaz && camcontrol eject 0:4:0'
alias upd 'umount /media/pd && camcontrol eject 0:1:0'
alias upcd 'umount /media/pcd && cdcontrol -f /dev/cd0 eject'

They should work with bash, as well as with csh (/etc/csh.cshrc).

I will definitely keep a copy of the article and the corresponding discussion due to the many inspirations for further aliasing.

Remember the recursion!
$ alias alias alias
Too dangerous to alias that
:-) Fri, 11 Jul 2008 02:10:00 GMT donotreply@osnews.com (Doc Pain) Comments http://osnews.com/thread?322477 http://osnews.com/thread?322477 i've aliased rm to essentially "what ???"
so I have to type the full path /bin/rm
and habitually use -iv "always"
......................
the time it takes to type "/bin/rm -iv"
seems to prevent the hurriedly-typing
errors (rm oops I meant cp) which
otherwise could occur.
HAS WORKED for over 3 years great here

This will allow you to clear the bash history and then send the exit command by simply typing "clh". If you've got a terminal opened and have used su to become root or another user, typing this in will clear root's (or whoever you've switched to) bash history and then return you to your original user. If you're yourself (ie. haven't used su to become root), it will clear your own history and close the terminal. Of course, it has to be in the .bashrc files of any user who wants to use it (in my case, both my own personal home and /root). This will also completely wipe out the history, which may not be desired by everyone.

Can MS powershell do the same?
