sort is way slow by default. This tells sort to use a buffer equal to half of the available free memory. It also will use multiple process for the sort equal to the number of cpus on your machine (if greater than 1). For me, it is magnitudes faster.

Here is the full function (got trunctated), which is much better and works for multiple queries.

function cmdfu () {

local t=~/cmdfu;

until [[ -z $1 ]]; do

echo -e "\n# $1 {{{1" >> $t;

curl -s "commandlinefu.com/commands/matching/$1/`echo -n $1|base64`/plaintext" | sed '1,2d;s/^#.*/& {{{2/g' | tee -a $t > $t.c;

sed -i "s/^# $1 {/# $1 - `grep -c '^#' $t.c` {/" $t;

shift;

done;

vim -u /dev/null -c "set ft=sh fdm=marker fdl=1 noswf" -M $t;

rm $t $t.c

}

Tested in bash on AIX & Linux, used for WAS versions 6.0 & up. Sorts by node name.
