in reply to Dealing with split

You can still use split(), you just have to get a bit creative:

$str = 'c:\temp\source\test\test.c@@main\com\etc c:\temp\source\test\t +est1.c@@main\com\test c:\temp\source\test\test3\test2.c@@main\com\etc +\test'; print map {"$_\n" if s/c:\\temp(.*?\.c)/$1/} split(/\s+|\@+/,$str);
UPDATE: Thanks to Grandfather for the heads up on interpolation of my \'s. I did this correctly in my tests, but posted it wrong...thanks again.

SECOND UPDATE: I don't what happened between testing and posting that this code isn't working. It worked fine on my box.

THIRD AND (hopefully) FINAL UPDATE: Got it now. Thanks again to Grandfather.

    You should really test your code before posting. All the \ dissapear from $str - use non-interpolating ' rather than " to fix that.

    There is a missing / in the split regex and an extra ) following it.

    Even after fixing those errors, when the code is run a "Use of uninitialized value in split" warning is issued and incorrect output is generated:

    \source\test\test.c@@main\com\etc c:\temp\source\test\test1.c@@main\co +m\test c:\temp\source\test\test3\test2.c@@main\com\etc\test

    dsb I am using your command and need a little more help. If I want to get all the files that has an extension not just .c how can i specify that? In the command I see that .c is specified. Can I specify mutliple patterns or use a wild card so that it gets all the files with extension.I have few .c files, .java and .xml and some directories in the $str. I just want to filter out the directories and get the files. ie in addition to
    'c:\temp\source\test\test.c@@main\com\etc c:\temp\source\test\test1.xm +l@@main\com\test c:\temp\source\test\test3\test2.c@@main\com\etc\test + c:temp\source c:\temp\source\java@@main\com\etc\test c:temp\source\ +java\test.java@@main\com\etc\test '
    I want the out put to be
    \test\test.c \source\test\test3\test2.c \test\test1.xml \source\java\test.java
    THanks
      You can tweak the regex to match all extensions or feed it an alternation that will find only certain extensions.
      # match any file extension print map {"$_\n" if s/c:\\temp(.*?\.(?:\w|\d)+?)/$1/} split(/\s+|\@+/ +,$str); # match only a few extensions print map {"$_\n" if s/c:\\temp(.*?\.(?:c|xml|java|etc))/$1/} split(/\ +s+|\@+/,$str);
      I think you'd be better of using runrig's snippet at Re: Dealing with split, though.
