commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

This command gives a model information of a computer. Also useful in determining the host is a VM machine or actual physical machine.
Useful in scripts while you just need an IP address in a variable.
Deletes thousands of files at one go, I'm not able to recall the exact # of files that rm can delete at one go(apprx. around 7000.)
useful for loops like for i in $(cat list_of_servers); do ssh -q $i hostname; done
if there is an unreachable server, you can just press ctrl + \ to skip that server and continue on with the loop
This will show all physically connected SATA (and SCSI) drives on your system. This is particularly useful when troubleshooting hard disks.... or when a mount point seems to be missing.
Create an ISO Image from a folder and burn it to CD (Os X)
I save this to bin/iptrace and run "iptrace ipaddress" to get the Country, City and State of an ip address using the http://ipadress.com service.
I add the following to my script to get a tinyurl of the map as well:
URL=`lynx -dump http://www.ip-adress.com/ip_tracer/?QRY=$1|grep details|awk '{print $2}'`
lynx -dump http://tinyurl.com/create.php?url=$URL|grep tinyurl|grep "19. http"|awk '{print $2}'
This will append the output of "command" to whatever file you're currently editing in vim. Who else has good vim tricks? :)
Split File in 19 MB big parts, putting parts together again via

The hyphen tells vim to open from STDOUT - saves having to create temporary files.
I've had this as mute.sh in my ~/bin/ for some time.
Adjust the
head -c
part for password length.
I use filenames like "hans@commandlinefu.com.gpg" and a vim which automatically decrypts files with .gpg suffixes.
This is my first attempt at converting all HTML files to UTF-8 file encoding, including all subfolders.
Theres probably a much more compact way to do it, but I'm quite proud of it with my windows background ;)
