question about PIPE and _mchar

[kas1e]

Well, question about PIPEs in amiga. I am using PIPE-1.5 from aminet, and all work fine, but, here is a settings:

Set _pchar "|"   ; PIPE
Set _mchar "||"  ; multicommand

Well, here is || as ';' in unix. Well, i was try to put Set _mchar ";", and it is not work, becouse aos already handled ';' char ? So, for what purposes aos take it, and , can it be to alises || to ; anyway ?

You can't use ';', it's the comment char (rest of the line is ignored).

Personally I use _mchar of "&&".

It is comment in shell window too ?[  ] I mean:

amiga shell:> cd libs: ; for what purposes needs comments in the command string ?

[Piru]

Code: [Select]

echo yes ; this is a comment you can't see

[kas1e]

I mean why need it comments in command string in shell ? Do you use it for any reassons ?

[Piru]

Comments are optional. Usually they're used in scripts to explain function of the script.

Functionally

Code: [Select]

echo comments are optional ; they really are
does exactly the same as:

Code: [Select]

echo comments are optional

It's the same code which interprets a command line, no matter if it is in a script or a window. So if you want to use comments in a script you also have to live with them in a window. Of course nobody enters comments in a shell window.
