in reply to I need to install PERL MODULE first and then use it in the same SCRIPT. Is it possible

Try:

BEGIN { # This unless block just seems a little clearer than the # way you were doing it. # unless (eval { require Term::Menus }) { print "INSTALLING PERL Term::Menus MODULE\n\n"; system("/opt/hp/hadooptools/validation/smoke/cpan.sh Term::Menus +"); } } use Term::Menus;

Explanation: use happens at compile-time, before your check/install code runs. Wrapping it in a BEGIN block "lifts" that code to compile-time.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
