Check These Out

Reconstruct standard permissions for directories and files in current directory

parrallel execution of a command on remote hosts by ssh or rsh or ...
parrallel execution of a command on remote host by ssh or rsh or ... very useful for cluster management (software update)

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Change a specific value in a path
Awk replaces the value of a specific field while retaining the field separator "/" .

Get each users commit amount

Generate random passwords (from which you may select "memorable" ones)
See: "man pwgen" for full details. Some Linux distros may not have pwgen included in the base distribution so you maye have to install it (eg in Mandriva Linux: "urpmi pwgen").

Merges given files line by line
In the above example all files have 4 lines. In "file1" consecutive lines are: "num, 1, 2, 3", in "file2": "name, Jack, Jim, Frank" and in "file3": "scores, 1300, 1100, 980". This one liner can save considerate ammount of time when you're trying to process serious portions of data. "-d" option allows one to set series of characters to be used as separators between data originating from given files.

Replicate a directory structure dropping the files
Here is how to replicate the directory structure in the current directory to a destination directory (given by the variable DESTDIR), without copying the files.

archive all files containing local changes (svn)
This works more reliable for me ("cut -c 8-" had one more space, so it did not work)

Nice beep
