need help--script to filter specific lines from multiple txt files - Shell Programming and Scripting

I-1 · #1 (**permalink**) 02-16-2007

Hi folks,

- I have 800 txt files
- those files are cisco router configs

Code:

router1.txt 
router2.txt
...
router800.txt

I want to accomplish the following:
- I want to have a seperate file with all the filenames that I want to process
- I want a script that goes trough all those filenames and pick out the "access-list" lines
- I want that this output is written to a separate file

I allready figured out how to get the ""access-list" lines out of 1 txt document:

Code:

#grep access-list /router/router1.txt

I have no clue how I should start.

Thanks,

Code:

while read file
do
     grep "access-list" $file >> tgt_file
done < file_lst

file_lst contains the file names

how do I achieve that between each file I put in something like this:

==============================================
router1.txt
==============================================
access-list 1 ................
access-list 2 ................

==============================================
router2.txt
==============================================
access-list 1 ................
access-list 2 ................

Code:

awk 'FNR==1{printf "===============\n%s\n===============\n",FILENAME}
/access-list/' router*.txt

Use nawk on Solaris.

Code:

while read file
do
     echo "=============================================="
     echo "$file"
     echo "=============================================="
     grep "access-list" $file >> tgt_file
     echo
     echo
done < file_lst
