Hey Guys I am having an odd problem using grep to ensure an array only contains distinct entries.
I have a list similar to the following in a file (short example of a much longer list) support01-FastEthernet1/0 support01-RH jnormandin-p370-1691-SH-Cpu-2 jnormandin-p370-1691-SH These entries may or may not appear multiple times within that list. I am trying to create an ARRAY containing each of these entries only once (a distinct list). I am using a grep statement: push @pingErrorsName, $element if (! grep (/\b$element\b/, @pingErrorsName)); * Where $element contains one of the above names in the list and @pingErrorsName is the distinct list of elements. What I am finding is that the array will contain all of the correct entries except: jnormandin-p370-1691-SH. It appears as though the grep is matching jnormandin-p370-1691-SH to the jnormandin-p370-1691-SH-Cpu-2 string (as it is a substring of the second one). Now I am using word boudnary anchors (\b) in the grep so I am confused as to why this is not working. Does anyone have any ideas as to why this is occuring and how I can prevent it? -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
