Hide files in ls, by adding support for .hidden files!

Sometimes I would like to see hidden files, prefix with a period, but some files or folders I never want to see (and really wish I could just remove all together).

Sort files in multiple directories by date

This sorts files in multiple directories by their modification date. Note that sorting is done at the end using "sort", instead of using the "-ltr" options to "ls". This ensures correct results when sorting a large number of files, in which case "find" will call "ls" multiple times.

Find biggest 10 files in current and subdirectories and sort by file size

This requires a version of GNU find that supports the -exec {} + action, but it seems more straightforward than the versions already posted.

Get ls to only show directories under .

Cleaner than adding -p to ls ( eg ls -alp ), this will tell ls to only output directories in the file listing, whilst maintaining all the usual other column elements of the ls output.

export iPad App list to txt file

This will generate the same output without changing the current directory, and filepath will be relative to the current directory.

Note: it will (still) fail if your iTunes library is in a non-standard location.
