Shell Programming and Scripting

Hello,

I am trying to grep, in bash, multiple specific files at once. I understand you can grep parameters file1 file2... fileN.

My question is how to do this when the specific files are not constant in name or quantity? (min 2 files, max 24 files)

Example 1: grep parameters file1 file2
Example 2: grep parameters file1 file2 file3 file4

I've tried using an array with [@] and a string with the files names separated by a space. Both don't work.

I do need to keep this to a single grep if possible.

Thanks!

Try

Code:

for file in file1 file2
do
grep parameters $file
done

Why should either of your examples not work? They do for me. Please post error messages.

Please show us EXACTLY what you have tried, and show us the output you got (including any diagnostic messages) in CODE tags. We can imagine ways to do what you have said that you are trying that should work perfectly.

We can also imagine lots of things you can do incorrectly. Rather than having us play guessing games, show us what you did and what results you got.

Also tell us what operating system and shell you're using!
