( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hi,
I have a .pl script. Inside the .pl script I am using a system command to call another script.

Consider the first script as 1.pl and the second one as 2.pl

There are print stmts in 2.pl and there are chances that 2.pl can throw error.

I have to catch the error in eval block and print the error in the script 1.pl

1.pl code snippet

... .. eval { system("perl 2.pl"); }; if($@) { print "the error that was thrown in 2.pl"; } ...


Pls note if 2.pl is displaying any output that should not be treated as error and caught in $@;

In reply to system command by palette

  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
