Hi, I'm a newbie here and this is my first question to the group, so forgive any lapse in etiquette. I wrote this script that is heavy in the use of system() and I run it using cygwin and it runs fine in that tool- however, when I use Strawberry Perl to run it there are a number of commands within the system() that it doesn't recognize. For example:

system ('grep -l "DATAmessage.*3\.0" *.xml > 3.0_files_arraydata.txt')
+; 
system ("mv temp_3.0_files_onixarraydata.txt 3.0_files_arraydata.txt")
+;  
system ("cat *files_arraydata.txt > data2.txt");
system ("rm data2.txt"); 

system ("sort -u data2.txt > data.txt");

It appears that the commands grep, mv, cat and rm all fail because "grep|mv|cat|rm is not recognized as an internal or external command, operation program or batch file" I also use sort, but I receive no error message for that command.

I have tried other things to swap out the system calls like File::Grep in place of the grep calls, but while File::Grep works, it was slower than molasses in the dead of winter in Strawberry Perl. I know many look-down on the use of system ();, but I find it to be very fast. Any suggestions? And thank you for reading.

• 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).
