ls -hog --> a more compact ls -l
I often deal with long file names and the 'ls -l' command leaves very little room for file names. An alternative is to use the -h -o and -g flags (or together, -hog). * The -h flag produces human-readable file size (e.g. 91K instead of 92728) * The -o suppresses the owner column * The -g suppresses the group column Since I use to alias ll='ls -l', I now do alias ll='ls -hog'

Extract tar.gz file with original permission
-x, --extract, --get extract files from an archive -p, --preserve-permissions, --same-permissions extract information about file permissions (default for superuser) -f, --file=ARCHIVE use archive file or device ARCHIVE -v, --verbose verbosely list files processed

execute a shell with netcat without -e
Shorter version with proper stderr redirection .

Export MySQL tables that begin with a string

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Delete only binary files in a directory
Please note that binary file checking is NOT perfect. So, use it with caution. It does not delete hidden files whose name has a leading '.' character. And it regards an empty file as a binary file.

Print current running shell, PID
works as well as echo $0, but also prints process id, which pts you're using. echo $SHELL doesn't always get updated when changing shells, so this is a better solution than that. Just one more variation on a theme.

list all crontabs for users
additionally use "find /etc/cron*" for cronscripts

Convert multiple flac files to mp3
make sure that flac and lame are installed sudo apt-get install lame flac

Bash logger
