Just a note I have seen hundreds of forums and this one is the best above the best. Always get quick answers with no attitudes and always get the help from the best people who really enjoy helping people. Is there a place to donate or help fund this great site??

My Perl question is I need to create a regular expression in Perl to find if anything except a positive integer was entered.

No letters or characters except a positive integer. For example the regular expression will check
12 good entry.
1a bad entry
4 good entry
1a bad entry
-3 bad entry
test bad entry

My attempt is not validating like I want it to:

if($DataEntry =~ !/d.*+)
{
   print "bad entry";
}
else
{
   print "good entry";
}

Please advise.

• 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).
