appending to PATH

[milica]

So many web sites state that $ENV{‘PATH’} = “/newpath:$ENV{‘ PATH’}”; should append to path.

When I include that in perl code, and echo $PATH afterwards, or just type env, there is no change in $path. ???

Any ideas? Thanks.

In a Perl script, the %ENV variable is actually a hash. Each variable in the hash is a key which has a value. One of those keys is "PATH", which contains the system path contents. The %ENV hash contains the CGI Envornment variables.

To print it out, use this:

print "Content-type: text/html\n\n";
print "<tt>\n";
foreach $key (sort keys(%ENV)) {
      print "$key = $ENV{$key}<p>";
}
 

To modify the hash, I would look up a tutorial on hashes if you don't already know how.
