"That's it. Not much to see here. The first command writes any cache data that hasn't been written to the disk out to the disk. The second command tells the kernel to drop what's cached. Not much to it. This invalidates the write cache as well as the read cache, which is why we have the sync command first. Supposedly, it is possible to have some cached write data never make it to disk, so use it with caution, and NEVER do it on a production server. You could ... but why take the risk?

As long as you are running a post 2.6.16 kernel,..."

curl -s ifconfig.me|tee >(xargs geoiplookup)

Functions: tee xargs

Show external IP and geolocation information.

Primary feature is the use of tee to echo IP _and_ send to geoiplookup command...Use IP as input for as many commands as you want with more >( [command] )

Thanks to http://www.commandlinefu.com/commands/view/6334/

Requires MaxMind DB and geoiplookup tool.

Sample output has IP obfuscated on first line, lines 2-4 from having MaxMind Country && MaxMind City DBs installed

Calls sudo tee like all the other lines, but also automatically reloads the file.

Optionally you can add

command Wq :execute ':W' | :q

and

command WQ :Wq

to make quitting easier

Find which directories on your system contain a lot of files.

Edit: much shorter and betterer with -n switch.

If you need to fix a randomly failing test (race condition), you need to run it until you get that hard-to-reproduce failure.

probably just like 1204, but uses tee as a filter (+ I actually understand how this one works)

You can find every file with png extension and redirect its output to file. Later you can find a string inside the file.

Functions: cd find grep md5sum sed tee

extracts path to each md5 checksum file, then, for each path, cd to it, check the md5sum, then cd - to toggle back to the starting directory. greps at the end to remove cd chattering on about the current directory.

Sometimes you might need to have two copies of data that is in tar. You might unpack, and then copy, but if IO is slow, you might lower it by automatically writing it twice (or more times)

echo "GRUB_INIT_TUNE=\"1000 334 1 334 1 0 1 334 1 0 1 261 1 334 1 0 1 392 2 0 4 196 2\"" | sudo tee -a /etc/default/grub > /dev/null && sudo update-grub

when using named pipes only one reader is given the output by default. Also, most commands piped to by grep use a buffer which save output until tail -f finishes, which is not convenient. Here, using a combination of tee, sub-processes and the --line-buffered switch in grep we can workaround the problem.

tar -cvf - $DIR_TO_BACKUP | tee >(md5sum > backup_md5.txt) > /dev/st0 && mt -f /dev/nst0 bsfm 1 && md5sum -c backup_md5.txt < /dev/st0

Backups $DIR_TO_BACKUP into tape, creating on the fly a MD5SUM file of the backup.

Then rewinds one record on tape and checks if it's well written.

This one is a little bit easier for those of us that aren't always root.

Watch any command (pipes ok, quotes be careful) and keep history in a file. Good for watching and recording any kind of status or error condition, file creations, etc. The choice of "who" as CMD was just to show an obvious usage.

Uses plenty of shell tricks that can be disassembled for simpler stuff. It's deliberately not perfect, but it is generic, and can be customized for your own uses. Had to shorten a little to meet 255 chars.

Better than "watch" how? It keeps a date log of what is going on, and tee'd output is plain-text.
