Grab IP address on machine with multiple interfaces

Instead of hard-coding in a check to scrape info from ifconfig based on a specific interface, do it in a more portable way. This works really well if you switch between wired, wireless, bluetooth or even VPN connections. You can get your current IP in a script (since it'll be something like tun0 instead of eth0 or wlan1). This uses a well known public ip address 8.8.8.8, but it doesn't actually connect to it, it just shows you the route it would take. Show Sample Output

Disconnect a wireless client on an atheros-based access point

This command will disconnect the user whose mac was specified from the current list of clients from the wireless network when the network card is working in access point mode. Works on atheros-based access points which use the madwifi driver (not sure, but don't think it will work on access points which are not atheros-based, as it uses the atheros's iwpriv extensions). It will not prevent the user from reconnecting to the network, but may force the user to roam to another AP, with stronger signal. Show Sample Output

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Watch contents of a file grow

In this case, I'm keeping an eye on /var/log/messages, but of course any file will do. When I'm following a file, I generally don't want to see anything other than what has been added due to the command or service I've executed. This keeps everything clean and tidy for troubleshooting.

Create POSIX tar archive

tar(1) and cpio(1) are not fully platform agnostic, although their file formats are specified in POSIX.1-2001. As such, GNU tar(1) might not be able to extract a BSD tar(1) archive, and ivce versa. pax(1) is defined in POSIX.1-2001. To extract an archive: $ pax -rf archive.tar

show the working directories of running processes

this shows the CWD of every running `java' command. YMMV but we often switch to a working directory for each service to start and run from there -- therefore this quicly shows what is running by a more meaningful name than command alone (the -bw prevents using blocking system calls which speeds this up quite a bit in the presence of remote mounted filesystems)

Using vim to save and run your python script.

This will save and execute your python script every time your press the F5 function key. It can also be added to your .vimrc: autocmd BufRead *.py nmap :w^M:!python % NOTE: the ^M is not just caret-M, it can be created by type: ctrl-v ctrl-m

Create a tar file with the current date in the name.

ping as traceroute

This command uses ping to get the routers' IP addresses to the destination host as traceroute does. If you know what I mean..

Compare copies of a file with md5

Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Diff remote webpages using wget

ThePirateBay.org torrent search

usage: tpb searchterm example: tpb the matrix trilogy This searches for torrents from thepiratebay and displays the top results in reverse order, so the 1st result is at the bottom instead of the top -- which is better for command line users
