  • I wrote this a long time ago, wondering why this wasn't floating around somewhere out there (at least not where I could find).. this seems much more simple than multiple aliases and can cd out of directories easier. Show Sample Output

  • This will make a false directory with the same file names as whatever directory you choose. This is wise to use when testing scripts that alter contents, filenames, or move files. I wrote this after an OOPS I made when renaming a directory of JPGs, PNGs, PSDs that were mixed. I recommend this as I lost over 2000 vacation pictures and some graphics I designed for software and web sites. :( NOTE: This only creates name copies, that data itself is not copied.

  • This is a simple solution to running a remote program on a remote computer on the remote display through ssh. 1. Create an empty 'commander' file in the directory where you intend on running these commands. 2. Run the command 3. Hop on another computer and ssh in to the PC where you ran the command 4. cd to the directory where the 'commander' file is. 5. Test it by doing the following: echo "xeyes" > commander 6. If it worked properly, then xeyes will popup on the remote computer. Combined with my other one liner, you can place those in some start-up scripts and be able to screw with your wife/daughter/siblings, w/e by either launching programs or sending notifications(my other one liner). Also, creates a log file named comm_log in working directory that logs all commands ran.

    while :;do if [ ! $(ls -l commander |cut -d ' ' -f5) -eq 0 ]; then echo "Ran command: $(less commander) @ $(date +%D) $(date +%r)" >> comm_log;"$(less commander)";> commander;fi;done

  • Run this command when you are physically at the computer you wish to send pop-up messages to. Then when you ssh in to it, you can do this: echo "guess who?" > commander guess who? will then pop up on the screen for a few moments, then disappear. You will need to create the commander file first. I mess with my wife all the time with this. i.e. echo "You have given the computer a virus. Computer will be rendered useless in 10 seconds." > commander lol

    while : ; do if [ ! $(ls -l commander | cut -d ' ' -f5) -eq 0 ]; then notify-send "$(less commander)"; > commander; fi; done

A command line calculator in Perl
Once I wrote a command line calculator program in C, then I found this... and added to it a bit. For ease of use I normally use this in a tiny Perl program (which I call pc for 'Perl Calculator') #!/usr/bin/perl -w die "Usage: $0 MATHS\n" unless(@ARGV);for(@ARGV){s/x/*/g;s/v/sqrt /g;s/\^/**/g}; print eval(join('',@ARGV)),$/; It handles square roots, power, modulus: $ pc 1+2 (1 plus 2) 3 $ pc 3x4 (3 times 4) 12 $ pc 5^6 (5 to the power of 6) 15625 $ pc v 49 ( square root of 49 ) 7 $ pc 12/3 (12 divided by 3) 4 $ pc 19%4 (19 modulus 4) 3 (you can string maths together too) $ pc 10 x 10 x 10 1000 $ pc 10 + 10 + 10 / 2 25 $ pc 7 x v49 49

Beep siren
Infinitely plays beeps with sinusoidally changing sound frequency. Ideal for alarm on an event.

Ease your directory exploration

Search some text from all files inside a directory

Watch TCP, UDP open ports in real time with socket summary.

Get all IPs via ifconfig
and, a lot uglier, with sed: $ ifconfig | sed -n '/inet addr:/s/[^:]\+:\(\S\+\).*/\1/p' Edit: Wanted to be shorter than the perl version. Still think that the perl version is the best..

disassemble binary shellcode
The options -b binary and -m are needed for disassembling raw machine code when it is not part of a full binary executable with proper headers.

Set your profile so that you resume or start a screen session on login
From screen's manpage: "Attach here and now. In detail this means: If a session is running, then reattach. If necessary detach and logout remotely first. If it was not running create it and notify the user. This is the author's favorite." Toss this in your ~/.bash_profile so that you never have that "oh crap" moment where you wanted to run something in screen and didn't.

Remove security limitations from PDF documents using ghostscript (for Windows)
#4345 also works under windows
