Re^2: Find Execution time of perl script??

No need to calculate start time: it is always available through $^T (see perlvar).

print time - $^T;

And for programs with so few liners, there is probably little need for use strict, use warnings, meaningful variable names, etc,. ( Some posters seem too vocal on such matters; with a little more encouragement, they might also advise on the java-way of doing things.)

True that warnings, strict, etc. may not be entirely necessary for programs that are only a half-dozen lines long, but: It's good to display them in sample code which new initiates may emulate You never know when your basic 6-line program may start evolving into something more substantial For some of us, `-wT` and `use strict` are such habits that it's more work to exclude them than to include them	[reply] [d/l] [select]

Too true. In fact, I use a vim skeleton.pl file that looks like so: `~ cat skeleton.pl #!/usr/bin/perl -w use strict; use Data::Dumper::Simple;` [download] So yes, in my case at least - it is actually more trouble for me to not use strict and warnings :)	[reply] [d/l]
