Thanks Paul & Filippos for the links, I think the 'intro' would be my best
starting point...

Maybe someone needs to come up with a representation for the space character
in documentation to highlight the fact that a space is required as it is
easily missed, by me anyway !!

Spaces (also "whitespace", any combination of various space/tab characters) can be very important in scripts as field and parameter separators. You'll soon get used to it if you write scripts on anything like a regular basis.


I also find it useful to think of the "[" in the "if" statement:

if [ x = y ]; then ...

as being the same as the command "test" (see man test). When you think of it ("[") as a command (which it is), the need for a space after it is more obvious in my mind.

Paul.
