Hi,
I have two questions, wish to get advice,
Question 1:
For a series of files:
cat a_*.o* | grep "WARNING"
Useless use of 'cat' (grep can open files)
some file like a_1.o12 has WARNING, but others does not have WARNING
How can I let grep returns the filename?
From your explanation it's not clear to me if you want -l or -H, but you
might just read 'man grep' and decide for yourself ;)
Not familiar with xargs, but you should probably read that manpage too.
To answer the question in your subject I think the correct command to
use is 'man' :)
Kind regards,
Andrei
I didn't realize I could find answer from manuals of grep.
Thanks,
