Consider this bash test script: $ bash -c 'for f;do echo "myarg: $f";done' TESTSCRIPT 'first arg' 'second arg' myarg: first arg myarg: second arg How might I drive the arguments sent to the above script with a tcl list? I want the method to to be generic enough, so it does not matter what is in the list. The only approaches that seem to work for me, involve figuring out a way to metaquote the arguments when required. But, I'm inexperienced w/tcl. -- thanks much, Tom -- roa6v@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org

I use this to think about quoting in Tcl: shell quoting: "double $interpolates", 'single $does_not' Tcl quoting: "double $interpolates", {braces $dont} -- Glenn Jackman "You can only be young once.
