Now texmacs is pleased to run "locate /arial.ttf" on a regular basis which takes about 20 seconds.

Why does it take so long?? Do you have PC XT? On my veeery slooooooow eeepc it returns immediately (finding nothing, admittedly).

That'll be why it is so quick.

Do you regularly run updatedb via cron? (I use fcron; if the laptop was switched off at night when updatedb should have been run, fcron runs it after I switch it on the next day).

I'm using mlocate with an up to date database of 525MB

I guess that's why it takes so long.

For the benefit of others I post a corrected version of my locate cacher (kept in /usr/local/bin/locate) - the one I posted recursed itself!

#! /bin/bash

ARGS=`echo "$*" | sed -e "s/[^a-zA-Z0-9]/-/g"`
CACHE=/tmp/locate-$USER-$ARGS
test -r "$CACHE" && exec cat $CACHE

if /usr/bin/locate "$@" > "$CACHE.tmp"
then mv "$CACHE.tmp" "$CACHE"
exec cat "$CACHE"
else r=$?
cat "$CACHE.tmp"
rm "$CACHE.tmp"
exit $r
fi
