Today I needed to choose an icon for an app. My simpler way: put all of /usr/share/icons in myicons folder and brows'em with nautilus. Then rm -r 'ed the entire dir.

No problem with word splitting. That should works on many Unix likes.

For those who don't have the symlinks command, you can use readlink. This command is not straightforward because readlink is very picky. The backslash in front of 'ls' means not to use an alias (e.g. color escape codes from an aliased 'ls' could mess up readlink), and the -1 (one) means to print the entries separated by newlines. xargs -l (the letter L) means to process each input separated by newlines as separate commands.

remove files with access time older than a given date.

If you want to remove files with a given modification time replace %A@ with %T@. Use %C@ for the modification time.

The time is expressed in epoc but is easy to use any other ordered format.

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

find ./ -type f -print0 | xargs -0 file -iNf - | grep video | cut -d: -f1

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:

find ./ -type f -print0 | xargs -0 file -iNf - | grep video | cut -d: -f1 | xargs -d'\n' /usr/share/doc/mplayer/examples/midentify | grep ID_LENGTH | awk -F "=" '{sum += $2} END {print sum/60/60; print "hours"}'

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

cut -d: -f1 /etc/passwd|xargs -n1 passwd -e

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

Liked command 4077 so I improved it, by doing all text manipulation with sed.

With this form you dont need to cut out target directory using grep/sed/etc.

I took java to make the find command simpler and to state that it works for any language supported by cpp.

cpp is the C/C++ preprocessor (interprets macros, removes comments, inserts includes, resolves trigraphs). The -fpreprocessor option tells cpp to assume the input has already been preprocessed so it will only replace comment lines with blank lines.

The -L 1 option tells xargs to launch one process for each line, indeed cpp can only process one file at the time...

Figures out total line contribution per author for an entire GIT repo. Includes binary files, which kind of mess up the true count.

If crashes or takes too long, mess with the ls-file option at the start:

git ls-files -x "*pdf" -x "*psd" -x "*tif" to remove really random binary files

git ls-files "*.py" "*.html" "*.css" to only include specific file types
