Check your unread Gmail from the command line
Checks the Gmail ATOM feed for your account, parses it and outputs a list of unread messages. For some reason sed gets stuck on OS X, so here's a Perl version for the Mac: $ curl -u username:password --silent "https://mail.google.com/mail/feed/atom" | tr -d '\n' | awk -F '' '{for (i=2; i

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Use modprobe to list all the dependencies of a certain kernel module. Handy when debugging system issues.

Extract title from HTML files
Case Insensitive! and Works even if the "<title>...</title>" spans over multiple line. Simple! :-)

View files opened by a program on startup and shutdown
Run this before you run a command in order to see what the command does as it starts. The -c flag is useful here as the PID is unknown before startup. All config files, libraries, logs, ports, etc used by the command as it starts up, (and shuts down) will be captured at 1s intervals and written to a file. Useful for debugging etc.

Disable the ping response
It really disables all ICMP responses not only the ping one. If you want to enable it you can use: $ sudo -s "echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all"

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"
