  • Suppresses all output to /dev/null. This could be expanded to check for a -l command line option to log the stderr to a file maybe -l file or -l to log to default quietly.log. I'm finding that I use it more often than one would think. Show Sample Output

    function quietly () { $* 2> /dev/null > /dev/null; };

  • the last person who posted used the most roundabout way to concatinate files, there's a reason there's a "conCATinate" command... Using this method, you also get to choose the order of the files, below another person just did *.txt > combined.txt which is fine but the order depends on the implementation of "cat" which is probably alphabetical order of filenames. Show Sample Output

    cat file1 ... fileN > combinedFile;

  • Add an alias to your .bashrc that allows you to issue the command xkcd to view (with gwenview) the newest xkcd comic... I know there are thousands of them out there but this one is at least replete with installer and also uses a more concise syntax... plus, gwenview shows you the downloading progress as it downloads the comic and gives you a more full featured viewing experience.

    echo alias xkcd="gwenview `w3m -dump|grep png | awk '{print $5}'` 2> /dev/null" >> .bashrc

  • This command toggles the touchpad on and off, when it's on, the right side scroll strip (annoying) and the tap-clicking are disabled, you can change this by changing occurances of 2 in the command to 0. this whole command can then be given a keyboard shortcut so that the touchpad is disableable without using a special fn key (which linux doesn't recognize on some computers) or a seperate button.

    if [ $(synclient -l | grep TouchpadOff | awk '{print $3}') = "2" ]; then synclient TouchpadOff=1; elif [ $(synclient -l | grep TouchpadOff | awk '{print $3}') == "1" ]; then synclient TouchpadOff=2; else synclient TouchpadOff=2; fi

  • the middle command between the ; and ; is the vi commands that insert that line into the last line of the file, the esc with the carets is literally hitting the escape key, you have to have the smbfs package installed to do it, I use it to access my iTunes music on my mac from my linux PC's with amarok so I can play the music anywhere in the house. among other things, it allows you to access the files on that share from your computer anytime you're on that network.

    sudo vi /etc/fstab; Go//smb-share/gino /mnt/place smbfs defaults,username=gino,password=pass 0 0<esc>:wq; mount //smb-share/gino

  • The above was done using the i386 flashplayer plugin, and was installed on a AMD64 machine running an AMD64 kernel and AMD64 programs. the resulting plugin install ultimately didn't work for swiftfox (but worked for iceweasel) without also covering it with a nspluginwrapper which took a bit of fenangaling to get to work (lots of apt-getting) but it is a nice feature to be able to trick installers that think you need i386 into running on a amd64, or at least attempting to run on amd64. Enjoy Show Sample Output

    setarch i386 [command [args]]

What's this? 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.

Flush and then immediately start watching a file
This is useful for keeping an eye on an error log while developing. The !^ pulls the first arg from the previous command (which needs to be run in a sub-shell for this shortcut to work).

Increment the filename of png in a given directory by one

Monitor cpu in realtime.

Anti Syn Ddos
Ddos syn attack

check open ports without netstat or lsof

Recursive grep of all c++ source under the current directory

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

Does a traceroute. Lookup and display the network or AS names and AS numbers.
From the man page. lft ? display the route packets take to a network host/socket using one of several layer-4 protocols and methods; optionally show heuristic network information in transitu -A Enable lookup and display of of AS (autonomous system) numbers (e.g., [1]). This option queries one of several whois servers (see options 'C' and 'r') in order to ascertain the origin ASN of the IP address in question. By default, LFT uses the pWhoIs service whose ASN data tends to be more accurate and more timely than using the RADB as it is derived from the Internet's global routing table. -N Enable lookup and display of network or AS names (e.g., [GNTY-NETBLK-4]). This option queries Prefix WhoIs, RIPE NCC, or the RADB (as requested). In the case of Prefix WhoIs or RADB, the network name is displayed. In the case of RIPE NCC, the AS name is displayed.

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"

a function to put environment variable in zsh history for editing
This only makes sense if you are using command line editing. Create the function in your current zsh session, then type eve PATH go 'UP' in your history and notice the current (editable) definition of PATH shows up as the previous command. Same as doing: PATH="'$PATH'" but takes fewer characters and you don't have to remember the escaping.
