Run a command when a file is changed

Recursively lists all files in the current directory, except the ones in '.snapshot' directory
This can be useful for those who have mounted NetApp file-systems with snapshot activated.

Go to parent directory of filename edited in last command
Uses the last argument of the last executed command, and gets the directory name from it. Use $!:t for the filename alone, without the dirname.

Get absolut path to your bash-script
Another way of doing it that's a bit clearer. I'm a fan of readable code.

Extract extention of a file

wget multiple files (or mirror) from NTLM-protected Sharepoint
If you have to deal with MS Sharepoint which is (rarely, let's hope) used in e.g. certain corporate environments). This uses Cntlm. For single files, just use cURL -- its NTLM authentication works quite well. # /etc/cntlm.conf: # Username account # Domain domain # Password ############ # Proxy 10.20.30.40 (IP of the sharepoint site) # NoProxy * # Listen 3128

Tracklist reaplace backspace to '-'
Requires perl 5.14 or greater

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"

Get the ip registered to a domain on OpenWRT
I use this in a script on my openwrt router to check if my DynDNS needs to be updated, saves your account from being banned for blank updates.

python2 -m CGIHTTPServer
In case you need to test some CGI scripts this does the job. It also has the functionality of a http server. Enjoy!
