For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Using command line args in TCL/Expect for Windows

Posted by MarkTChristy (MarkTChristy), 23 February 2005
Here I go again.    I did some searching but just can't find a specific to windows example.

I wrote a script called test.tcl, I invoke it like this...
c:\tcl>tclsh test.tcl <hostname>

I need <hostname> to be any valid host I want. However, in the code - how do I reference it. I have tried simple statements such as...
exp_send_user "Your command line arg was: \$1"
exp_send_user "Your command line arg was: $1"
... and the first one nicely prints out $1 as I would expect, the second one says it does not know the variable '1'.

How do I do this .... (lame question #2)....

They're provided in a list called argv (that's independent of operating system).


dolphin:/Library/WebServer/live_cgi-bin/net graham$ tclsh -v -p demo.txt
% puts $argv
-v -p demo.txt
% foreach item $argv {
puts $item

YES! Blinded by the light  

foreach item $argv {
puts $item

I got it, thanks. I am now doing better.

More later -- thanks again for the head-light on that subject, I just couldn't find it or make it work.
