Running linux sftp command in perl doesnt work

When I run this in the terminal, it works

/usr/bin/sftp -o "IdentityFile=/opt/apps/doc/bin/id_rsa" -b /opt/apps/doc/bin/batch.txt DMS2@convpc1

However, when I run this in perl script, nothing happen

system("/usr/bin/sftp -o \"IdentityFile=/opt/apps/doc/bin/id_rsa\" -b /opt/apps/doc/bin/batch.txt DMS2@convpc1");

I have been spending the entire day trying to figure out how to sftps my file and I cannot figure out the problem? Any suggestions?

Edit: I did some more testings. I put the entire command in a test.sh file. I ran the test.sh from terminal, it works. I changed the perl file so it is system("/opt/app/doc/bin/test.sh") and then ran it, nothing happen. I added printing statements before the system command, they work, but the system command still doesn't work since I don't see my file being moved.

Try below

    $result = "/usr/bin/sftp -o \"IdentityFile=/opt/apps/doc/bin/id_rsa\" -b /opt/apps/doc/bin/batch.txt DMS2\@convpc1";
    system($result);

Are you getting any syntax errors? Try "perl -cw scriptname" and see the result.

I would suggest Net::SFTP which is very convenient for establishing SFTP connection.

The system command may be eating the quote character, and the '@' character needs escaping as \@.

Try this to see if you are really running the command you are trying to run:

my $cmd = "/usr/bin/sftp -o \"IdentityFile=/opt/apps/doc/bin/id_rsa\" -b /opt/apps/doc/bin/batch.txt DMS2@convpc1";

sys($cmd);

sub sys {
    my ($cmd) = @_;
    print "About to run '$cmd'\n";
    (system($cmd) == 0) or die "Unable to run '$cmd' : $!";
}
