Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

I'm trying to produce this behaviour:

grep 192.168.1 *.txt

By passing a string into grep via Xargs but it is going on the end instead of as the first parameter.

echo 192.168.1 | xargs grep  *.txt

I need to tell xargs (or something similar) to put the incoming string between 'grep' and '*' instead of on the end.

How do I do this?

$ echo 192.168.1. | xargs -I{} grep {} *.txt


Sample files:

$ cat {1..3}.txt

Example run:

$ echo 192.168.1. | xargs -I{} grep {} *.txt

Why not to use

grep $(comand-producing-output) *.txt
