The exec command treats ampersands in its arguments specially, e.g. for making execution asynchronous. This can be a problem if an argument, like an URL, contains ampersamds.

Would anybody know a workaround in case $url contains character '&' e.g. http://127.0.0.1/cgi-bin/script?var1=abc&var2=xyz
Benjamin Riefenstahl replied: exec plays tricks with quoting which make it impossible for me to get the right command executed in Tcl 8.3.4. What works on W2K here though is this:
set url "http://www.tcl.tk?hello&hi" set shell [open "|[file join $env(COMSPEC)]" w] fconfigure $shell -buffering line puts $shell "start \"\" \"$url\"" puts $shell exit close $shell
I hope this works on Windows 9x/Me, too.
