CSH: echo a string having []
I am trying to use echo in CSH and getting an error.

I want to use [] to tell the user which parameters are optional.

Code:
    set msg2 = "[-Base=] [-Data=] -Inmod= [-Fout] -Nxz= [-Npop=] -Varp="
    echo $msg2

Seems to work if you quote the echo:

Code:
    set msg2 = "[-Base=] [-Data=] -Inmod= [-Fout] -Nxz= [-Npop=] -Varp="
    echo "$msg2"

It might be a globbing issue, but as it's C-Shell, I'd just quote the echo!

It's standard procedure to point you to these links:

Thanks. Does the [] have special meaning? As when I remove them echo shows no problem.

From the csh man page:
Quote:
The search string may be a glob-
pattern (see Filename substitution) containing `*', `?', `[]' or `{}'.
and

Quote:
Glob-patterns which do not use `?', `*', or `[]'
suggests that they may. These quotes may, or may not be relevant to your code, but to be honest, you should read the manual page and other documentation for CSH.
