cmd1 | cmd2

will call cmd2 only once with cmd1 output as argument. What i want is call cmd2 one by one with each line of cmd1 output as argument. Maybe something looks like:

cmd1 | map cmd2

I know i can write one by myself, just want to know is there built-in support already?

---

for i in `cmd1`; do cmd2 $i; done

should do it.

---

cmd1 | xargs -l cmd2

This is my favorite way. Thanks to Paulo Ebermann!

---

cmd1 | while read x
do
  cmd2 $x
done

---

use xargs

cmd1|xargs cmd2

eg:

ls xyz*|xargs grep "abc"

abc will be searched in all the files whose name starts with xyz
