Read file then grep the line
Dear all,

I am reading a file that has 1 column. While reading I must find the line references from the another file. The following shell doesn't works.

Please help

Code:
#!/bin/bash
while read filename; do
grep ${filename} fs_full.dat >>  unprocfull.dat;
done < unproc.dat

But when echo the lines the shell works well.
Code:
#!/bin/bash

while read filename; do
#grep ${filename} fs_full.dat >>  unprocfull.dat;
echo ${filename}
done < unproc.dat

for i in `cat unproc.dat`
do
grep $i fs_full.dat >> unprocjull.dat
done

beware of the quotes around cat unproc.dat they are back tics(under the ~ usually) not quotes (under the double quotes " usually)
