List only directories, one per line

Normally, if you just want to see directories you'd use brianmuckian's command 'ls -d *\', but I ran into problems trying to use that command in my script because there are often multiple directories per line. If you need to script something with directories and want to guarantee that there is only one entry per line, this is the fastest way i know Show Sample Output

How to sum lines with decimals in awk

Read all lines using decimal marker as point, then add all them up and outputs the result.

automount samba shares as devices in /mnt/

the middle command between the ; and ; is the vi commands that insert that line into the last line of the file, the esc with the carets is literally hitting the escape key, you have to have the smbfs package installed to do it, I use it to access my iTunes music on my mac from my linux PC's with amarok so I can play the music anywhere in the house. among other things, it allows you to access the files on that share from your computer anytime you're on that network.

Download Apple movie trailers

Copy the link to an HD movie trailer in to this command. It's more eleganant if it's put in a to a script, taking the URL as input.

Convert text to picture

Hide or show Desktop Icons on MacOS

Hides all Files and Folders on the MacOS Desktop. To show files and folders, type "true" instead of "false". "Finder" at the end is case sensitive, "finder" doesn’t work

List all installed PERL modules by CPAN

This command will give you the detailed information about the installed perl modules i.e. installed path, Link type, version, files etc.

find the rpm package name that provides a specific file

For Linux distributions using rpm (eg Mandriva), this command will find the rpm package name that provides a file.

Remove grep itself from ps

When you 'ps|grep' for a given process, it turns out that grep itself appears as a valid line since it contains the RE/name you are looking for. To avoid grep from showing itself, simply insert some wildcard into process' name.

Dump android contacts, sms

Crude, but works. Note for security, /data/ will be inaccessible unless your device has been *rooted*. On the other hand, if a device has been rooted, its data is now wide open to anyone with a USB cable and the above "one-liner". `adb` is one of the platform tools in the android SDK. To get SMS messages: $ adb pull /data/data/com.android.providers.telephony/databases/mmssms.db ; sqlite3 -batch
