Query an NFS host for its list of exports

Perl oneliner to print access rights in octal format
This prints file access rights in octal - useful when "stat" is unavailable.

Remove Thumbs.db files from folders

floating point operations in shell scripts
Calculator for shell. Similar performance and basic usage as 'bc', but with more advanced features. Not installed on most systems by default.

Print a list of all hardlinks in the working directory, recursively
libpurple likes to hardlink files repeatedly. To ignore libpurple, use sed: | sed '/\.\/\.purple/d'

Delete .svn directories and content recursively
Use carefully have rm -rf ;-)

Stream audio over ssh
This one doesn't need to convert to wav.

Prevent overwriting file when using redirection
If you set noclobber to on, bash won't allow redirection to overwrite existing files . $ set -o noclobber command turn the option on (default it s off ) . You can still append information but not overwrite the file .to turn it back off use : $ set +o noclobber . I use it because i overwrite a file by accident , after thought , content of the file was very important , creating a one more file mean nothing for my hard disk (we are not anymore on the 64 k memory time) , but content of file is far much important . What we call exeprience :(

Protect directory from an overzealous rm -rf *
Forces the -i flag on the rm command when using a wildcard delete.

Start an X app remotely
Launch a gui app remotely. In this example smplayer is installed on the remote machine, and movie.avi is in the remote user's home dir. Note that stdout/stderr is still local, so you'll have feedback locally, add '&>/dev/null' to suppress. This is surprisingly not well known (compared to running an X app locally via ssh -X). (NB. if your distro requires ~/.Xauthority file present, then try -fX if you have problems) Resubmitted (and trimmed, thanks sitaram) due to ridiculous voting on previous submission. Fingers crossed, it gets a better rating this time.
