RE: A silly (I think) question

Eric,

 

from this code it looks like your

splitting on the entire variable in $line.

Split will pull out whatever _expression_

that you give it and return what's left.

 

For example,

 

$line = "c:\\;;c:\\test\\;c:\\test\\test;";

@fields = split(/;/,$line);

@fields will be ("c:\", "", "c:\test", "c:\test\test")

 

Hope this helps:)

 

John

Subject: A silly (I think) question

I've got an issue with a split function, or at least I THINK that's where I'm having the problem.

 

Given that $line is one line of output from a command in column format, I run the following:

 

$line = `some command`;

chomp $line;

@fields = split $line;

 

This should produce a list of strings from $line, right?

 

Any idea why I'd have an empty list when $line contains the expected data as verified from a print command?

 

Thanks in advance!

Eric
