  • Kill all processes that listen to ports begin with 50 (50, 50x, 50xxx,...)

    Run netstat as root (via sudo) to get the ID of the process listening on the desired socket. Use awk to 1) match the entry that is the listening socket, 2) matching the exact port (bounded by leading colon and end of column), 3) remove the trailing slash and process name from the last column, and finally 4) use the system(…) command to call kill to terminate the process. Two direct commands, netstat & awk, and one forked call to kill. This does kill the specific port instead of any port that starts with 50. I consider this to be safer.

    sudo netstat -plnt | awk '($4 ~ /:50$/){sub(/\/.*/, "", $7); system("sudo kill " $7)}'

back ssh from firewalled hosts
host B (you) redirects a modem port (62220) to his local ssh. host A is a remote machine (the ones that issues the ssh cmd). once connected port 5497 is in listening mode on host B. host B just do a ssh 127.0.0.1 -p 5497 -l user and reaches the remote host'ssh. This can be used also for vnc and so on.

This will open the manpage for "foobar", and display all instances of "searched_string". You can traverse through them by pressing "n"

Map the slot of an I/O card to its PCI bus address
Recent hardware may or may not enumerate *both of* these values

Find Duplicate Files (based on size first, then MD5 hash)
If you have the fdupes command, you'll save a lot of typing. It can do recursive searches (-r,-R) and it allows you to interactively select which of the duplicate files found you wish to keep or delete.
