i'm testing the script now... the advisory was to do

while read i j < file1
do
   mv file2 file2.tmp
   sed -e "s/\ $i\$/\ $j/" < file2.tmp > file2
done

where file1 contains
value1	replace1
value2	replace2

and file2 contains something like
.... valueX
.... valueY
.... valueX
.... valueZ

i.e. to iteratively do the replacement for all sets valueX - replaceX

problem is that the "while command" reads all the time only the first 
line of the file :o( what i'm doing bad? (script shell is /bin/ksh)

regards,
lubos
