Shell Programming and Scripting

I am not sure if i am doing this correctly since it returns quickly. i need to grep for a keyword in all files in a directory

grep keyword /mydirectory

is that correct? I just want to know which files have a keyword in it.

i am using korn shell in solaris 5.1. There does not appear to be a -r option in this version.


grep -r "keyword" /path/pathdir
grep: illegal option -- r
Usage: grep -hblcnsviw pattern file . . .

Try:

Code:

grep "keyword" /mydirectory/*

grep will take file(s) as parameter, not directories. So try

Code:

grep keyword /mydirectory/*

To search recursively you can add -R to some versions of grep. I often use on the command line something like

Code:

find .| grep pattern

If you don't get output in which file the pattern was found, you can add maybe a -l to your grep.

You can try this..

for all files in current directory

Code:

grep Keyword *

for all files in current and subdirectories

Code:

grep -R Keyword *

if you want to list only filenames

Code:

 
grep -l -R keyword *

use -l (form look) option:-

Code:

grep -l "pattern" /path/to/Mydirectory/*

Or (if you don't mind searching subdirectories but do want to avoid searching directory files):

Code:

find /mydirectory/ -type f -print | while read FILENAME
do
       grep -l "keyword" "${FILENAME}"
done

But why does that requires a loop,

Code:

find /mydirectory/ -type f -exec grep -l 'keyword' {} \;
