perl flush stdout /contrib/famzah
Hi all - I am developing a perl 5.8 application using the new threading model. I use this technique (thanks Jenda!) to dup STDIN to a temp file handle:... The easeast thing would be to use IPC::Open3, you cna chekc out perldoc perlipc for other methods of redirection.

Hi, I have this shell command --> xmllint --schema schema1.xsd file1.xml 1>/dev/null When executed gives me this "file1.xml validates." Now I want to catch this output "file1.xml validates" in a variable in perl.... This works for STDERR, which is 90% of what I want, but what I'd still like to do is learn how to send all of STDERR to the text widget by default, if possible, so when I open a file, do a database connection or transaction, telnet, etc. I get the errors in a scrollling text window.
passing "stderr " to a subroutine.. The UNIX and Linux
Can someone tell me how to change STDERR to output to a file then change it back to its original output.... But Perl supports writing to STDOUT, so that this redirection works.

- So, Perl inherits the streams pointed to by STDIN, STDOUT and STDERR from the shell. If you need to re-connect them to other streams the way you did, you should first save a reference to the original filehandles in some variables beforehand, so that when you need to restore you can reinitialize them using these references saved.
