open man pages in Preview.app (caches generated pdfs in ~/.manpath)

man.sh

#!/bin/sh
#Based on this Mac OS X Hint:

CACHE=~/.mancache
mkdir -p $CACHE
COMMANDS="$@"
for f in $COMMANDS
do
    if [ -e $CACHE/$f.pdf ]; then
  echo found existing man page in cache: $CACHE/$f.pdf
	open $CACHE/$f.pdf
    else
	echo generating man page for $f
	ps=`mktemp -t $f`.ps
	man -t $f > "$ps"
	if [ $? != 0 ]; then 
	    echo man page for $f not found | /usr/local/bin/growlnotify
	else
	    /usr/local/bin/ps2pdf $ps $CACHE/$f.pdf
	    open $CACHE/$f.pdf
	fi
    fi
done

i should say that it "opens" the man page in whatever is configured to open pdf files...
