Sorry, that could be described a bit better, yes.

What if I would want to do this in a script:

grep string file*

This would obviously not work then, as it would only grep in one file?
Code:
#!/bin/bash
grep $1 $2

grep string file* would work (assuming "file*" doesn't expand to too many files).

If you want to do this from the command line, then:
Code:
$ ./myScript "some string to search for" file*

$ cat myScript
STR=$1
shift
grep "$STR" "$@"

Thanks, that works like a charm. Smilie What does shift do?

shift = move along, nothing to see here Smilie

Code:
$ cat myScript
echo $1 $2 $3
shift # get rid of first argument ($1)
echo $1 $2 $3

$ ./myScript A B C
A B C
B C
