Question

I can download a file from another server using wget command on a Linux command line, example:

wget ftp_site_name/file_name

But I could not download the same file when I run wget inside a perl script

system "/usr/bin/wget ftp_site_name/file_name";

or

system "wget ftp_site_name";

Here is the snippet of the error message:

Resolving ftp site  ...xx.xx.x.xx

Connecting to ftp site|xx.xx.x.xx|:xx... connected.

Logging in as anonymous ... Logged in!

==> SYST ... done.    ==> PWD ... done.

==> TYPE I ... done.  ==> CWD (1) /pub/??/??/ ...

No such directory `pub/??/??/'.

Any suggestions?

It is hard to tell what’s wrong without the actual error message but I have some guesses:

If the path contains wild chars or spaces use apostrophe or escaping.

my $ftpname="/pub/some path with spaces/works_with_wildchar?/";
my $out = `wget '$ftpname'`;
print "out:\n$out\n";

or
my $ftpname="/pub/some path with spaces/works_with_wildchar?/";
my $out = qx!wget $ftpname!;
print "out:\n$out\n";
