What if you want to view the whole year with cal -y? You have to do your alias this way: (for tcsh)

alias cal "cal \!* | sed 's/ S  M Tu  W Th  F  S/ S  M  Ti O  To F  L/g'"

Now the alias will accept cal options and replace every occurrence of the weekdays string if there are many.

how come this cal function doesn't get stuck in an infinite loop?

would it be more logical to use

alias cal "/usr/bin/cal \!* | sed 's/ S M Tu W Th F S/ S M Ti O To F L/g'"

Tcsh seems to know that loops can occur, and checks for them. If I made up an alias called cal, where cal wasn't the first command called, tcsh would report it.

It would complain on such a thing as: (not that it makes sense, but it's just an example.)

% alias cal 'date | cal'
% cal
Alias loop.

perhaps TCSH checks back to the first alias made?

I know this is harder for most people, but an alternative would be to recompile the 'cal' command from source (after changing the day & month names to your language).

The source code is available after you register (for free), agreeing to Apple's Open Source License: source for cal

The "proper" way to do this would be to use the LANG environment variable to define what language to show text in. However, it doesn't appear that OS X has proper locale support, or cal wasn't built with it.

On most *nixes, you could do:

export LANG=fr_FR
cal

Oh well ... I bet the fink version of cal supports this.

While OS X does support locale, programs need to be explicitly written to use the locale facility in order for it to have any effect. The 'cal' program does not make any effort to use other languages. The source code shows the following:

char *month_names[12] = {
        "January", "February", "March", "April", "May", "June",
        "July", "August", "September", "October", "November", "December",
};
char *day_headings = " S  M Tu  W Th  F  S";

And which "fink version of cal" were you referring to? I don't see any version of 'cal' available from fink.

I spoke too soon about fink. You are right: there is no cal package in fink. I just assumed there was. Oops!

Gcal is a command line calendar with many features. Compiles easily on 10.2.x. Not sure if it's available with Fink.
