FIND command question revisited
I'm using this in AIX to find what file contains the value 'batch' in it, in all directories.


find / -type f -exec grep -l batch {} /dev/null \;


My question is, what if I only wanted to search *.sh files, and I wanted to pipe the results to a file called 'batch_find.txt'. How could I code this? Thanks in advance.

Not sure what is the point of /dev/null Smilie

Code:
find / -name "*.sh" -type f -exec grep -l batch {} \; > batch_find.txt

Thanks, I'll try that and get back to you. As for whats the point of /dev/null.....beats me....that was suggested here last time. Maybe someone with more experience can answer that one Smilie

When grep is supplied with multiple files to search it outputs the filename followed by a colon on the beginning of every matched line. Appending /dev/null to the command enforces this behaviour, even when only one file is actually searched.

xargs is a much more efficient way of doing this as it supplies grep with multiple filenames at a time, causing fewer invocations:

Code:
find / -name "*.sh" -type f  | xargs grep -l batch > batch_find.txt
