  • i'm using gawk, you may get varying mileage with other varieties. You might want to change the / after du to say, /home/ or /var or something, otherwise this command might take quite some time to complete. Sorry it's so obsfucated, I had to turn a script into a one-liner under 255 characters for commandlinefu. Note: the bar ratio is relative, so the highest ratio of the total disk, "anchors" the rest of the graph. EDIT: the math was slightly wrong, fixed it. Also, made it compliant with older versions of df. Show Sample Output

    t=$(df|awk 'NR!=1{sum+=$2}END{print sum}');sudo du / --max-depth=1|sed '$d'|sort -rn -k1 | awk -v t=$t 'OFMT="%d" {M=64; for (a=0;a<$1;a++){if (a>c){c=a}}br=a/c;b=M*br;for(x=0;x<b;x++){printf "\033[1;31m" "|" "\033[0m"}print " "$2" "(a/t*100)"% total"}'

  • creates associative array from apache logs, assumes "combined" log format or similar. replace awk column to suit needs. bandwidth per ip is also useful. have fun. I haven't found a more efficient way to do this as yet. sorry, FIXED TYPO: log file should obviously go after awk, which then pipes into sort.

    awk '{array[$1]++}END{ for (ip in array) print array[ip] " " ip}' <path/to/apache/*.log> | sort -n

  • This is good for cleaning up log files without having to erase the entire contents of the file, and allows you to keep the most recent entries to the log only

    sed -i 's/`head -n 500 foo.log`//' foo.log

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.

convert a line to a space

Convert numbers to SI notation
converts any number on the 'stdin' to SI notation. My version limits to 3 digits of precious (working with 10% resistors).

Create passwords and store safely with gpg
Adjust the $ head -c part for password length. I use filenames like "[email protected]" and a vim which automatically decrypts files with .gpg suffixes.

move you up one directory quickly
Alias a single character 'b' to move to parent directory. Put it into your .bashrc or .profile file. Using "cd .." is one of the most repetitive sequence of characters you'll in the command line. Bring it down to two keys 'b' and 'enter'. It stands for "back" Also useful to have multiple: alias b='cd ../' alias bb='cd ../../' alias bbb='cd ../../../' alias bbbb='cd ../../../../'

Schedule a command while one is already running.
Useful when you have only one terminal session e.g. ssh. and want to queue up another command after the currently running has finished(in case if you forget to run that command). Originally used as ; python-updater when running emerge. When I have noticed that a package failed due to that command not run.

Get file access control list

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Convert all files for iPhone with HandbrakeCLI

Which processes are listening on a specific port (e.g. port 80)
