Answer 1

Right. You have 2 options: enclose the pattern with " , but then you have to protect \ from being parsed by Tcl instead of the regxp. Or you can use regexp -nocase [subst -nocommands -nobackslashes {something here:\s+$MYSTR}].

PS: put always {} around the expression:

if {[regexp -nocase [subst -nocommands -nobackslashes {something here:\s+$MYSTR}]} then {
...
}
