Send a local file via email
This just reads in a local file and sends it via email. Works with text or binary. *Requires* local mail server.

Annoying PROMPT_COMMAND animation
unset PROMPT_COMMAND to disable.

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").

Browse shared folder when you're the only Linux user
Under Ubuntu smbclient is part of the samba package. With the version I use (3.0.28a) cd-ing into folders with spaces in the name is a drag. You have to put the folder name in quotes: smb: \Shared\> cd "Marketing and PR"

find text in a file
this will find text in the directory you specify and give you line where it appears.

Start a SOCKS proxy to avoid a restrictive firewall
You may go to Internet by means of your home ssh server. You must configure your local proxy to send traffic through the proxy. Many programs allows that: firefox, pidgin, skype, gnome, etc. Your home ssh server must listen in any of the ports permitted by your enterprise firewall. That usually includes 80 and 443.

securely erase unused blocks in a partition
This command securely erases all the unused blocks on a partition. The unused blocks are the "free space" on the partition. Some of these blocks will contain data from previously deleted files. You might want to use this if you are given access to an old computer and you do not know its provenance. The command could be used while booted from a LiveCD to clear freespace space on old HD. On modern Linux LiveCDs, the "ntfs-3g" system provides ReadWrite access to NTFS partitions thus enabling this method to also be used on Wind'ohs drives. NB depending on the size of the partition, this command could take a while to complete.

Apply new patch for a directory (originDir)

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)
