Re: Run a tcl script from a shell script

2005-10-02T11:31:17-04:00

I want to launch an interactive tcl script from a shell script, but when I try, it seems that the standard input channel gets messed up. For example, the following code:
Code:
puts -nonewline stdout "What is your name?: " flush stdout set name [gets stdin]
returns the following error:
Code:
error reading "file0": I/O error while executing "gets stdin"
..but the error only occurs when I launch the tcl script from a shell script. It works fine when I run it directly from bash prompt. Any ideas how to fix this?

are you trying to do something like this ?

Code:

#!/usr/local/bin/tclsh8.4fileevent stdin readable [list [puts STDIN->[gets stdin]]]vwait _forever_

...and yes, it runs fine for me in both cases: when given as argument to tclsh on the shell prompt, and when tclsh is invoked from a shell script

just a little note... you are aware that your script is running from sh not from bash?!

on Linux, /bin/sh is merely a symlink to bash

Tivosh is indeed TivoShell, a customized TCL installation for Tivos. I don't have a Linux PC I can test this on, so can you copy the "test" script from my original post and try to run it from bash?...Then from a simple shell script? Thanks!!

Here is the shell script, which basically just launches two tcl scripts. The first tcl script is not interactive, so it runs fine. The second tcl script chokes when I run it from this script, but works fine when I run it from bash prompt. Thanks in advance.

Code:

#!/bin/shtivosh netconfig.tcltivosh setSSIDwep.tcl
