Check These Out

check open ports without netstat or lsof

ls not pattern
I've been looking for a way to do this for a while, get a not pattern for shell globs. This works, I'm using to grab logs from a remote server via scp.

git remove files which have been deleted
I've used technicalpickles command a lot, but this one handles whitespaces in filenames. I'm sure you want to create an alias for it :)

Extract audio stream from an AVI file using mencoder
This commands saves the output in the audio directory. The portion ${file/%avi/mp3} uses bash string replacement to replace the avi to mp3 within the ${file} variable.

32 bits or 64 bits?

Enter a command but keep it out of the history
Put a space in front of your command on the command line and it will not be logged as part of your command line history.

Debug redirects between production reloads
Watches the headers of a curl, following any redirects and printing only the HTTP status and the location of the possible redirects.

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"

Which files/dirs waste my disk space
I added -S to du so that you don't include /foo/bar/baz.iso in /foo, and change sorts -n to -h so that it can properly sort the human readable sizes.

find xargs mv
