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: awk cut grep md5sum sed xargs

This functionality seems to be missing from commands like dpkg. Ideally, I want to duplicate the behavior of rpm --verify, but it seems difficult to do this in one relatively short command pipeline.

largest() { dir=${1:-"./"}; count=${2:-"10"}; echo "Getting top $count largest files in $dir"; du -sx "$dir/"* | sort -nk 1 | tail -n $count | cut -f2 | xargs -I file du -shx file; }

You can simply run "largest", and list the top 10 files/directories in ./, or you can pass two parameters, the first being the directory, the 2nd being the limit of files to display.

Best off putting this in your bashrc or bash_profile file

FILE='mp3.list';LNNO=`wc -l $FILE|cut -d' ' -f 1`;LIST=( `cat $FILE` );for((;;)) do SEED=$((RANDOM % $LNNO));RNNO=$(python -c "print int('`openssl rand -rand ${LIST[$SEED]} 8 -hex 2>/dev/null`', 16) % $LNNO");mplayer ${LIST[$RNNO]};sleep 2s; done

User: Sebasg
Functions: cpio cut diff
Tags: svn

Get the list of changed files between revision 43 and HEAD revision: svn diff . -r43:HEAD --summarize

Strip extra 8 characters from every line: cut -c9-99999

Copy the listed files to home/me/destination: cpio -pvdmu ~/destination

Make a plain copy (-p), list files being copied (-v), create needed directories (-d), preserve modification time (-m), overwrite unconditionally (-u)

This, like the other commands listed here, displays installed arch packages. Unlike the other ones this also displays the short description so you can see what that package does without having to go to google. It also shows the largest packages on top. You can optionally pipe this through head to display an arbitrary number of the largest packages installed (e.g. ... | head -30 # for the largest 30 packages installed)

looks at html for "ip" (it's a CSS class), then a little of cut and egrep to get IPv4 address.

I use this oneliner into conky.

find . \( -iname '*.cpp' -o -iname '*.h' \) -exec wc -l {} \; | sort -n | cut --delimiter=. -f 1 | awk '{s+=$1} END {print s}'

Searches for *.cpp and *.h in directory structure, counts the number of lines for each matching file and adds the counts together.

This is the closest you can get to "reset printing system" from the command line. Giving credit back to J D McIninch from an apple forum back in 2009.

Also shows files as they are found. Only works from a tty.
