  • This will take the packages matching a given `apt-cache search` query (a collection of AND'd words or regexps) and tell you how popular they are. This is particularly nice for those times you have to figure out which solution to use for e.g. a PDF reader or a VNC client. Substitute "ubuntu.com" for "debian.org" if you want this to use Ubuntu's data instead. Everything else will work perfectly. Show Sample Output

    apt-popcon() { (echo \#rank; apt-cache search "$@" |awk '$1 !~ /^lib/ {print " "$1" "}') |grep -Ff- <(wget -qqO- http://popcon.debian.org/by_inst.gz |gunzip); }

  • This is like `cd -` but doesn't echo the new directory name, which is preferable (to me) for an alias, e.g. alias cdo="cd $OLDPWD"


    -2
    cd $OLDPWD

  • A tweak using Patola's code as a base, this full-width green matrix display has all the frills (and all the printable characters). You don't need the surrounding parens if you don't care about losing globbing capabilities. Z-shell (/bin/zsh) needs neither the parens nor the `set -o noglob` Screen shot (animated): http://desmond.imageshack.us/Himg32/scaled.php?server=32&filename=matrixh.gif&res=landing If it's too slow, try lowering the `sleep 0.05` or even replacing it with `true` (which is faster than `sleep 0`). I squashed it as narrow as I could to conserve space, though somebody could probably squeeze a char or two out. Enjoy!

    (set -o noglob;while sleep 0.05;do for r in `grep -ao '[[:print:]]' /dev/urandom|head -$((COLUMNS/3))`;do [ $((RANDOM%6)) -le 1 ] && r=\ ;echo -ne "\e[$((RANDOM%7/-6+2));32m $r ";done;echo;done)
