This template code is for starting a typical tclsh application.
#! /bin/sh
# the next line restarts using tclsh \
exec tclsh "$0" ${1+"$@"}This is a little more sophisticated than the code suggested on the tclsh man page (see tcl), and is explained in great detail on exec magic.
Typical patterns to continue are:
# verify Tcl version requirements
package require Tcl 8.4 ;# My application uses [lset]
# process stdin:
while {[gets stdin line]>=0} {
#do something with $line
}
# process argv:
foreach arg $argv {
# do something with $arg
}
