What's the linux command to do 'grep' on multiple file????

[Black_Rabbit]

Hi I was wondering if this is the correct command when I want to do 'grep' on multiple files in the same folder

cat 1.txt | cat 2.txt | cat 3.txt |cat 4.txt |grep text

Thanks!

no.
but grep can do it natively, and even recursive

[Black_Rabbit]

but this code can still perform the function I need right? if not can you please let me know the correct command?? Thanks!

No, your approach would only grep in 4.txt.

You can probably figure out the correct command yourself.
Hint: You only need grep and your four txt files.

man grep

Thank you!

I change the command to cat 1.txt 2.txt 3.txt 4.txt |grep text

You dont need cat
