Hello,

I was trying to do some search through my files with grep, and in some cases, the program doesn't seem to function, also it appears like it does. For example, if i try:

grep -R hello .

where, . is ~, initially it processes the files, but at some point it stops, like it goes to sleep. The same with

grep -R mmap Documentatie/USO

but this time it does nothing, also it appears like it works.

Strange is that when i try, for example

grep -R hello /usr

it works, without stopping. Or when grepping the /.

The answer is why is that? What is the problem? Thanks in advance.

you can use strace <command> to check what your command tries to do. Hopefully you will find grep works without problems just no new file found.

Ok, i might have found the problem, it is a named pipe/fifo that it stops when it reaches to it, or when it opens it.

Yes, that's it. Thanks for the clue.

I generally use this command for recursive search / grep:

find . -exec grep -Hni <whatever> {} \;

but that's just me.

Thanks, i was trying to do it like this some time ago, but for some reason it didn't worked, so i discovered the other method finally. Thanks for enlightening my spirit.
