Get the line containing "inet addr:" and the line before that, get down to only the first line, and then get the first word on that line, which should be the interface.

eliminates "l" and "o" characters change length by changing 'x' here: cut -c 1-x

The command gives size of all files smaller than 1024k, this information, together with disk usage, can help determin file system parameter (e.g. block size) or storage device (e.g. SSD v.s. HDD).

Note if you use awk instead of "cut| dc", you easily breach maximum allowed number of records in awk.

This reports directly using mtx what Tape is in the mailslot (Import/Export tray) on most autoloaders.

You will need to change /dev/sg13 to your autloader device file and adjust the 63 at the end to your tape label character length(ie 63 for 8 characters 64 for 9 characters)

same thing as the other

Require ips and ipcalc

grabs your local IP Address.

Same thing just a different way to get there. You will need lynx

no fancy grep stuff here.

I know this has been beaten to death but finding video files using mime types and printing the "hours of video" for each directory is (IMHO) easier to parse than just a single total. Output is in minutes.

Among the other niceties is that it omits printing of non-video files/folders

PS: Barely managed to fit it within the 255 character limit :D

Uses mime-type of files rather than relying on file extensions to find files of a certain type.

This can obviously be extended to finding files of any other type as well.. like plain text files, audio, etc..

In reference to displaying the total hours of video (which was earlier posted in command line fu, but relied on the user having to supply all possible video file formats) we can now do better:

I modify 4077 and marssi commandline to simplify it and skip an error when parsing the first line of lsmod (4077). Also, it's more concise and small now. I skip using xargs ( not required here ). This is only for GNU sed.

For thoses without GNU sed, use that :

Alternately for those without getent or only want to work on local users it's even easier:

Note that not all implementations of passwd support -e. On RH it would be passwd -x0 (?) and on Solaris it would be passwd -f.

Run this as root, it will be helpful to quickly get information about the loaded kernel modules.

handles file names with spaces and colons, fixes sort (numeric!), uses mplayer, same output format as other alternatives

Similar but using mediainfo instead of totem-something

Sort .avi movies by time length, print the longest first, and so on...

Figures out what has changed in the last 12 hours.

Change the author to yourself, change the time since to whatever you want.

Sometimes, you don't really care about all the other information that ifconfig spits at you (however useful it may otherwise be). You just want an IP. This strips out all the crap and gives you exactly what you want.
