Using tar in windows

[peterneve]

I have written a script which upload a tar file. The next step is to untar it. I have tried:

$com="tar -xf \"$savefile\"";
system("$com");

and

$com="tar -xf \"$savefile\"";
open (TEST, "$com");
close TEST;

both of which just hang. The tar file is extracted (with the first option) but the rest of the page is never displayed on the browser.

I am using windows and active perl and the tar.exe is one that comes with exceed...

Any ideas?

Thanks in advance

Get your tar command to work on the command line first. Assuming the working command is:

tar -xf "mysavefile"

$com = 'tar -xf "mysavefile"';
system("$com");

or

$savefile = "mysavefile";
$com = 'tar -xf "$savefile"';
system("$com");

should both work.

Try wrapping the entire command (including double quotes) in the qq function, e.g.,

$savefile = "mysavefile";
$com = qq("tar -xf $savefile");
$result = system($com);

Hi, thanks for all the responses.

I have found that the problem was simply that the tar program that the system defaulted to was a windows program, which never closed after finishing it's operation, so Perl was waiting for it to finish forever. My original code works now that a DOS tar program is being used.
