Question

Got a quick question here:

Say I’m trying to separate the lines of a group of files, they all look like this:

pid text number

And I want to separate the lines into different files using the pid, how can I achieve this?

So far, I’ve tried something like:

cat files | grep '\([0-9]\{3\}\)' > $1.txt

That ofcourse, doens’t work.. any ideas?

Answer 1

The file with pids :

$ cat /tmp/l
123 azerty
234 qwerty
456 bepo

The awk code :

$ awk '/^[0-9]{3}/{print $0 > $1".txt"}' /tmp/l

The output of ls :

$ ls
123.txt
234.txt
456.txt
