Hi All,
I need to pass a variable to perl script from bash script, where in perl i am using if condition. Here is the cmd what i am using in perl
Code:
FROM_DATE="06/05/2008"
TO_DATE="07/05/2008"

"perl -ne ' print if ( $_ >="$FROM_DATE" && $_ <= "$TO_DATE" ) ' filename"

filename has following data :-
Code:
06/05/2008-07:59
06/05/2008-07:59
06/05/2008-07:59

NAME
ouse - syntactic sugar to make Mouse one-liners easier SYNOPSIS
# create a Mouse class on the fly ... perl -Mouse=Foo -e 'has bar => ( is=>q[ro], default => q[baz] ); print Foo->new->bar' # prints baz # loads an existing class (Mouse or non-Mouse) # and re-"opens" the package definition to make # debugging/introspection easier perl -Mouse=+My::Class -e 'print join ", " => __PACKAGE__->meta->get_method_list' DESCRIPTION
ouse.pm is a simple source filter that adds "package $name; use Mouse;" to the beginning of your script and was entirely created because typing perl "-e'package Foo; use Mouse; ...'" was annoying me... especially after getting used to having "-Moose" for Moose. INTERFACE
"ouse" provides exactly one method and it is automatically called by perl: "oose->import()"> Pass a package name to import to be used by the source filter. DEPENDENCIES
You will need Filter::Simple and eventually Mouse INCOMPATIBILITIES
None reported. But it is a source filter and might have issues there. SEE ALSO
oose for "perl -Moose -e '...'" AUTHOR
For all intents and purposes, blame: Chris Prather "<perigrin@cpan.org>" ...who wrote oose.pm, which was adapted for use by Mouse by: Ricardo SIGNES "<rjbs@cpan.org>" COPYRIGHT AND LICENSE
