UNIX for Dummies Questions & Answers

Hi,

I am using the Korne shell to try and get the filename, line number and the line of text using grep e.g.

find ./ -type f -name "*.java" -exec grep -nf test.txt '{}' \;
(test.txt contains strings to search)

will return the line number and the line of text.

grep -l would return the filename but grep -ln doesnt return the filename, the line number and the line of text.

Is it possible to do this using grep ?, or would I have to use something like awk ?

I would appreciate if anybody can help me

thanks

It's a bit of a kluge, but try

Code:

grep -nf test.txt /dev/null '{}' \;

grep -l doesn't gives file name.it gives only the file name.So your code is true . Then what is wrong .

if use grep like these ;

grep -nf test.txt file1 file2 ...
grep -nf test.txt *
grep -nf test.txt *.java

it gives filename:linenumber:text

the problem is when you give file name to grep so it assumes that you know the file name so it doesnt write file name

when you use your code above when it finds a file it executes
grep -nf test.text filexx(known file)

you must find a way of using
grep -nf text.txt *.java

you could do it something like this.

Firs create a script called, say mygrep, and put in it:

Code:

#!/bin/sh
grep -nf test.txt "$1" | sed -e "s!^!$1:!"

The you can do this:

Code:

find . -type f -name \*.java -exec ./mygrep {} \;

Hi thanks a lot Kahuna, that works great
