  • display a smiling smiley if the command succeeded and a sad smiley if the command failed

    you could save the code between if and fi to a shell script named smiley.sh with the first argument as and then do a smiley.sh to see if the command succeeded. a bit needless but who cares ;) Show Sample Output

  • Safe Russian Roulette (only echo, don't delete files)

    Shows "Bang!" in a chance of 1 out of 6, like in the original game with the gun (spin every round). Otherwise, echoes "Click...". If feeling brave you can also do: [ $[ $RANDOM % 6 ] == 0 ] && echo 'Bang!' && a really killer command || echo 'Click...' Show Sample Output

  • skipping five lines, at top, then at bottom

    Strangely enough, there is no option --lines=[negative] with tail, like the head's one, so we have to use sed, which is very short and clear, you see. Strangely more enough, skipping lines at the bottom with sed is not short nor clear. From Sed one liner : # delete the last 10 lines of a file $ sed -e :a -e '$d;N;2,10ba' -e 'P;D' # method 1 $ sed -n -e :a -e '1,10!{P;N;D;};N;ba' # method 2 Show Sample Output

  • Combo matrix

    This is longer than others on here. The reason for this is I have combined two different matrix commands so it would work on all computers. I logged onto my server through a computer and it worked fine. I logged into my server through a mac and it looked $4!t so I have made one that works through both. Show Sample Output

Single use vnc-over-ssh connection
This command 1. SSH into a machine 2. Tunnels VNC port to your local computer ("-L 5900:localhost:5900") 3. Runs a single use vnc server ("x11vnc -safer -localhost -nopw -once -display :0") 4.

Poor's man Matrix script
This creates a matrix of letters that run forever until you hit Ctrl-C simulating "The Matrix" effect... just for fun :) You may want to try the -n and -y switch to change the "FX" LOL! e.g.: pwgen -ny 3

subtraction between lines
It's allways strange for me to see sed and awk in the same command line if you can avoid it

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Uses the data in the /proc system, provided by the acpid, to find out the CPU temperature. Can be run on systems without lm-sensors installed as well.

List all symbolic links in current directory that matches regexp
Perl alternative to list symlinks with a clumsy regexp filter: place the regex instead of he example 'libxml' and end it with a wildchar to see the results (previous cd on dir). Is it possible change the '-l' test for '-d' and it will search for directories. [Same applies for -x and -X. See $(perldoc -f -x) for more tests]. I use it quite often when dealing with shared libraries...
