Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Functions: cut du find sort tail xargs
Tags: disk usage

Often you need to find the files that are taking up the most disk space in order to free up space asap. This script can be run on the enitre filesystem as root or on a home directory to find the largest files.

tr -cs A-Za-z '\n' | sort | uniq -ci

Functions: sort tr uniq
Tags: sort uniq tr

Gives the same results as the command by putnamhill using nine less characters.

tr A-Z a-z | tr -cs a-z '\n' | sort | uniq -c
tr A-Z a-z | tr -d "[[:punct:]][[:digit:]]" | tr ' /_' '\n' | sort | uniq -c
tr A-Z a-z | tr -d 0-9\[\],\*-.?\:\"\(\)#\;\<\>\@ | tr ' /_' '\n' | sort | uniq -c

sudo du -sm * | sort -n

User: wabi
Functions: du sort sudo

sudo is optional, but to find out about all files, it is nice, or else run as superuser, ie: su -c 'du -sm * | sort -n'

User: miniker84
Functions: sort

Works in sort (GNU coreutils) 7.4, don't know when it was implemented but sometime the last 6 years.

netstat -n | grep '^tcp.*<IP>:<PORT>' | tr " " | awk 'BEGIN{FS="( |:)"}{print $6}' | sort | uniq -c | sort -n -k1 | awk '{if ($1 >= 10){print $2}}'
2010-09-16 21:06:30
User: guptavi
Functions: awk grep netstat sort tr uniq

This command is primarily going to work on linux boxes.

and needs to be changed, for example



svn log 2>&1 | egrep '^r[0-9]+' | cut -d "|" -f2 | sort | uniq -c
feh --bg-center `ls -U1 |sort -R |head -1`
wget -O- -q http://www.nomachine.com/download-package.php?Prod_Id=2067 | sed -n -e 'H;${x;s/\n/ /g;p;}' | sed -e "s/[Hh][Rr][Ee][Ff]=\"/\n/g" | cut -d "\"" -f1 | sort -u | grep deb$

Functions: comm echo sort

the comm utility (opposite of diff) show commonalities in files (in this case strings)

find /path/to/dir -type f -name '*.*' | sed 's@.*/.*\.@.@' | sort | uniq

User: putnamhill
Functions: find sed sort

If your grep doesn't have an -o option, you can use sed instead.

find /path/to/dir -type f | grep -o '\.[^./]*$' | sort | uniq
svn status | awk '{print $2}' | xargs du | sort -n | tail
git log --format='%aN <%aE>' | awk '{arr[$0]++} END{for (i in arr){print arr[i], i;}}' | sort -rn | cut -d\ -f2-

Functions: awk cut sort
Tags: git

Gets the authors, sorts by number of commits (as a vague way of estimating how much of the project is their work, i.e. the higher in the list, the more they've done) and then outputs the results.

sort -t $'\t' -k 2 input.txt

User: postrational
Functions: sort

Use this BASH trick to create a variable containing the TAB character and pass it as the argument to sort, join, cut and other commands which don't understand the \t notation.

sort -t $'\t' ... join -t $'\t' ... cut -d $'\t' ...
