How to compile a list of file?

I have a file name grp.c then i have a list of test file,
First i gcc -Wall -o grp grp.c

Then my question is that, what is the command that use to run a list of with grp.c.
I know that to run 1 file, is to use grp things to find < grp.c

Thanks in advance

Please try to explain what you mean by "then i have a list of test file". That doesn't mean anything to me.

If you want to cmpile list of files then better write makefile..

Here's a tip - paste your actual code, actual commands and actual output.

> I have a file name grp.c then i have a list of test file,
So for example,

you do this for one test file
grp test1.txt

you do this for many test files
grp test*.txt

you do this for a list of test files
ls test*.txt > list.txt
grp `cat list.txt`

Complete the implementation of grp program so that it implements the following features:

* ability to read input from a list of files specified on the command line (note that it must display the file name for any matching lines)
* the -v option to print lines that do not match the pattern
* the ^ anchor to indicate that the string should appear at the beginning of the line
* the $ anchor to indicate that the string should appear at the end of the line.



This is what i am suppose to do for my homework.
So how can i compile and test my program.

This is use to compile and run for one file:
compile the program via the command:

% gcc -Wall -o grp grp.c

You can then test it by running the executable on its own source code via the command:

% grp abc < grp.c
% grp line < grp.c

You're not going to get that by redirecting stdin. What your instructor wants you to do is allow someone to type like:

grp searchstring file1 file2 file3

That way your search string is the first argument and every argument after that is a file to search for the string in. If you're still confused look at the man page for grep...it's the same sort of thing.

Ahh, get it, thanks
