Do you mean linuxcommand.org?

Which commands were giving you syntax errors? I'd be quite surprised if that website had syntax errors in its examples!

yes , linuxcommand.org

well, i tried the same program, as written on my computer and it didnt give the results they said it would, here s the example given, ofcourse i saved it in a file rather than directly on the prompt !

[me@linuxbox me]$ function today {
> echo "Today's date is:"
> date +"%A, %B %-d, %Y"
> }
[me@linuxbox me]$

there doesn't seem to be any problem with the syntax of that function

Quote:

sycamorex@debian205:~$ function today {
> echo "Today's date is:"
> date +"%A, %B %-d, %Y"
> }
sycamorex@debian205:~$ today
Today's date is:
Wednesday, December 26, 2007
sycamorex@debian205:~$

When you create a file:
$ emacs today_date

Quote:

#!/bin/bash

function today {
echo "Today's date is:"
date +"%A, %B %-d, %Y"
}

today
exit 0

$ chmod +x today_date
$ ./today_date
Today's date is:
Wednesday, December 26, 2007
