Hi there
I'm trying to write a cgi script that will run a executable file (securely, with any luck). The executable itself is a bit tricky, because it needs a file (which I have uploaded onto the server) .. but I can't feed the program the file from the command line, I can only give it the name of the file once the program is running .. so normally, if I run the program from the command line i have to use a pipe.
This is what I have come up with so far. Any suggestions much appreciated.
#!/usr/bin/perl use CGI; # eventually the text file will be sent to this excutable via the uplo +ad script $file = 'http://www.mywebpage/uploaded_files/file.txt'; # path to program my $prog = 'http://www.mywebpage/cgi-bin/executableprog'; my $q = new CGI; my $pid = open PIPE, "-|"; die "Cannot fork $!" unless defined $pid; unless($pid) { exec PROG or die "Cannot open pipe to executableprog: $!"; print PROG "$file\n"; close PROG; }
This code should result in a text file being created. I guess I have to determine where that will be placed on the server too? I have only just started playing with cgi and would appreciate any advice thrown my way. Thanks a lot.

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
