'all files' switch for grep?
 
If I type 'grep alias .bashrc' a whole load of stuff comes up. However, if I type 'grep alias *' nothing comes up. Is there some switch for including 'hidden' files - like the -a switch for ls?

Not known according to the man page. But
Code:

grep alias .* *
works.

The wildcards are expanded by the shell, not by grep.

If you have a directory containing these files:

Code:

.hidden
.hidden2
file
another

And you entered this:

Code:

grep alias *
The shell actually expands the '*' and grep sees this:

Code:

grep alias file another
By default '*' doesn't include files starting with a dot. You can explicitly put a dot before the asterisk to get hidden files only. Or both ".* *" to get all files.
