List the full path of some files.

You can add ".*" on the end if you want to display hidden files.

Parses /etc/group to "dot" format and pases it to "display" (imagemagick) to show a usefull diagram of users and groups (don't show empty groups).

human_filesize() { awk -v sum="$1" ' BEGIN {hum[1024^3]="Gb"; hum[1024^2]="Mb"; hum[1024]="Kb"; for (x=1024^3; x>=1024; x/=1024) { if (sum>=x) { printf "%.2f %s\n",sum/x,hum[x]; break; } } if (sum<1024) print "1kb"; } '}

Converts IP octets to hex using printf command. Useful for generating pxeboot aliases in the pxelinux.cfg folder.

I find it useful when I want to add another crontab entry and I need to specify the appropriate PATH.

I give ''whichpath'' a list of programs that I use inside my script and it gives me the PATH I need to use for this script.

''whichpath'' uses associative array, therefore you should have Bash v4 in order to run it.

See sample output.

i=60;while [ $i -gt 0 ];do if [ $i -gt 9 ];then printf "\b\b$i";else printf "\b\b $i";fi;sleep 1;i=`expr $i - 1`;done
SCALE=3; WIDTHL=10; WIDTHR=60; BAR="12345678"; BAR="${BAR//?/==========}"; while read LEFT RIGHT rest ; do RIGHT=$((RIGHT/SCALE)); printf "%${WIDTHL}s: %-${WIDTHR}s\n" "${LEFT:0:$WIDTHL}" "|${BAR:0:$RIGHT}*"; done < dataset.dat

WIDTHL=10 and WIDTHR=60 are setting the widths of the left and the right column/bar. BAR="12345678" etc. is used to create a 80 char long string of "="s. I didn't know any shorter way.

If you want to pipe results into it, wrap the whole thing in ( ... )

I know that printing bar graphs can be done rather easily by other means. Here, I was looking for a Bash only variant.

Check the API. You shouldn't need sed. The print-newline at the end is to prevent zsh from inserting a % after the end-of-output.

Also works with http://v.gd

arp-scan -I eth0 -l | perl -ne '/((\d{1,3}\.){3}\d{1,3})/ and $ip=$1 and $_=`nmblookup -A $ip` and /([[:alnum:]-]+)\s+<00>[^<]+<ACTIVE>/m and printf "%15s %s\n",$ip,$1'

Watch the temperatures of your CPU cores in real time at the command line. Press CONTROL+C to end.

GORY DETAILS: Your computer needs to support sensors (many laptops, for example, do not). You'll need to install the lm-sensors package if it isn't already installed. And it helps to run the `sensors-detect` command to set up your sensor kernel modules first. At the very end of the sensors-detect interactive shell prompt, answer YES to add the new lines to the list of kernel modules loaded at boot.

This command will delete all branches in your git repository other than next and master. I use this to cleanup my git repos after making multiple branches and merging them back into next. It's much faster than individually deleting each expired branch using:

git branch -D <branch_name>
cls(){ printf "\33[2J";} or, if no printf, cat >cls;<ctrl-v><ctrl+[>[2J<enter><ctrl+d> cls(){ cat cls;}

this leaves the cursor at the bottom of the terminal screen, where your eyes are.

ctrl-l moves it to the top, forcing you to look up.

The first argument is the interpreter for your script, the second argument is the name of the script to create.
