Extended man command
This microscript looks up a man page for each word possible, and if the correct page is not found, uses w3m and Google's "I'm feeling lucky" to output a first possible result. This script was made as a result of an idea on a popular Linux forum, where users often send other people to RTFM by saying something like "man backup" or "man ubuntu one". To make this script replace the usual man command, save it as ".man.sh" in your home folder and add the following string to the end of your .bashrc file: alias man='~/.man.sh'

Simple complete system backup excluding files or directories
You can exclude more system folders or individual files which are not necessary for the backup and can be recreated after the restore procedure, like /lost+found, /mnt, /media, /tmp, /usr ... Restoring the above backup procedure is as simple as becoming root and typing: $ tar zxpf backup.tgz -C / You can extract any file or directory out of the backup.tgz file for recovery, for instance, if you have a corrupt or mis-configured fstab file, you could simply issue the command: $ tar zxpf backup.tgz /ect/fstab -C / Other options: v add verbose option to see files processed A far safer solution is to restore the desired files under a different directory, and then compare, move, or update the files to their original locations afterward.
