passing arguments to a shell script from a perl script - Perl

Hi

You can actually actually indeed do this from within a perl script.
You can also set environment variables from within perl. I'm sure
you will get a few responses on this one as there are various ways,
the simplest way would be to do:
______________
my $script_to_execute = "script_name" ;
my $parameters = "one two three" ;
my $shell_call = $script_to_execute . " $parameters" # note the
space

system($shell_call)
______________
Hope the above helps.
cheers

Code called by system inherits the perl environment.
Try this:
perl -e '$ENV{PATH} .= ":/new/path"; system "echo \$PATH";'

Just set values in %ENV and your child process will inherit them. No need
for this complicated workaround.

You're not doing anything with the environment other than passing it
along implicitly.

You'd have to modify %ENV.
