If it didn't give any output, there were no matches.

To redirect the output from command to file, use command > file

The command can be a complex one, such as for f in stuff; do ... done >file

XRI01IFTMIN AGFA AGFADKCPH

In the above line i want to take the value from 49 position to 17 characters.

All the files in the folder start with XRI01 as shown above.

I dont knw why it didnt match anything. As files are there in the folders with such criteria.

Thanks

Karan

I misunderstood your requirement; I thought we should look for XRI01 starting at position 49.

Code:
for file in archive/080[89]/arc_transferred/*; do
    grep '^XRI01' "$file"| head -1 | cut -c49-66
done >file

Again, you might want to replace the grep | head | cut with a sed or Perl one-liner.

Code:
    sed -e '/^XRI01/!d' -e 's/.{48}\(.{1,17}\).*/\1/' -ep -eq "$file"

If your sed doesn't understand {m,n} try with \{m,n\} or maybe switch to Perl or something.
