List all execs in $PATH, usefull for grepping the resulting list
While it seems (to me at least) a little counter-intuitive to filter on name first, this requires less work for find, as it allows it to immediately discount any files that do not match the name directly from the directory listing on disk. Querying against file attributes requires reading the file attributes, which is performed for all files matching any name based predicates.

Find distro name and/or version/release
Works for most distributions, tested on Ubuntu, Fedora, CentOS, Gentoo, SUSE, RedHat. Debian and Slackware: $cat /etc/*version

Have netcat listening on your ports and use telnet to test connection
This will start a netcat process listening on port 666. If you are able connect to your your server, netcat will receive the data being sent and spit it out to the screen (it may look like random garbage, so you might want to redirect it to a file).

Apply permissions only to files
To apply only to dirs: $ chmod 755 $(find . -type d) Use -R parameters for recursive walk.

Rename all files in lower case
rename is a really powerfull to, as its name suggests, rename files

Shows size of dirs and files, hidden or not, sorted.
Very useful when you need disk space. It calculates the disk usage of all files and dirs (descending them) located at the current directory (including hidden ones). Then sort puts them in order.

Using column to format a directory listing

Gets the english pronunciation of a phrase
Usage examples: say hello say "hello world" say hello+world

encrypt and post or get and decrypt from sprunge using gpg symmetric encryption option
create simple encrypted notes to yourself using a passphrase on sprunge.us

uniq without pre-sorting
Reads stdin, and outputs each line only once - without sorting ahead of time. This does use more memory than your system's sort utility.
