Hi ,

I have two files.
One has 100 rows like
XXX XR_DEF
YYY Y_DEF
...

Another file has 200 rows like
AR_DEF 1
Y_DEF 0
XR_DEF 100
...

I want to make another file like
XXX 100
YYY 0
...

If any pattern of 1st file is not found in 2nd then just ignore.
Please suggest me solution of this problem.

Thanks
Mukesh

Porgram:

#!/usr/bin/sh

cp 100.txt tmp_1.txt

cat 200.txt | while read LINE
do
set $LINE
sed -e "s/ $1/ $2/" tmp_1.txt > tmp_2.txt
mv tmp_2.txt tmp_1.txt
done

cat tmp_1.txt

Output:

XXX 100
YYY 0
