Re: FILEHANDLE question on AIX machine

I believe this is actually part of the shell command to open that file. It redirects STDOUT and STDERR to a file (shell's, not perl's). As for the "|", I don't know. On Mar 3, 2006, at 1:12 PM, Families Laws wrote: 2>&1 |

FILEHANDLE question on AIX machine

I have to maintain a perl script, and encounter the following section: can anyone help me to understand what is the purpose of ". 2>&1 |" ? This is a AIX machine. Thanks. unless (@errors) { open(FILEHANDLE, "$PATH_TO_WSADMIN -f $tmpFile ". ' 2>&1 |'); while () { if

Re: filehandle question

: is it possible to open a filehandle on a file change one line in that file : without outputing to another file. You can open the file, seek() to a particular position in it, and start overwriting the file at that position, but when you reach the end of that line, you'll keep on writing past it
