Pro paranoiky predkladam tuto verzi:

#!/bin/bash
# program vezme vsechny regularni soubory v aktualnim a rekurzivne
# vnorenych adresarich ... verze 0.2 ;-)
# pouziti: script cesta co_nahradit cim_nahradit

PATH=/bin:/usr/bin:/sbin:
WDIR=/tmp/mojetmp.$$
NUM=0

if [ "$#" != "3" ] ; then
	echo "pouziti: $0 cesta co_nahradit cim_nahradit"
	exit
fi

umask 077

while   test -e "${WDIR}${NUM}" ; do
        NUM="$((NUM+1))"
done

if ! mkdir "${WDIR}${NUM}" ; then
        exit
fi

find "$1" -print | while read f ; do
	if [ -f "$f" ] ; then
		FTMP="${WDIR}${NUM}/tmp.$$"
		sed "s/$2/$3/g" <"$f" >"$FTMP"
		echo "pracuji na $f ..."
		mv "$FTMP" "$f"
	fi
done

rmdir  "${WDIR}${NUM}"

# KONEC
