Hello, PHP gurus,
I have a command that I want to run using system function. The
command exploits temporary named pipes in the place of temporary files.
my command is
paste <(cut -f1 file1) <(cut -f2 file2) > final_file
It works perfectly well if I just type it in my interactive
shell. But if I do a
<?php
$cmd = " paste <(cut -f1 file1) <(cut -f2 file2) > final_file";
system($cmd);
?>
I got the syntax error msg as
"sh: -c: line 1: syntax error near unexpected token `('". I have tried
to 'escapeshellcmd' the command and run it in system, then I got
paste: invalid option -- f
Try `paste --help' for more information.
Also tried exec. I really want to take advantage of the
temporary named pipes so I don't have to worry about the temporary files
generated. I've been googling around without much help. Could anyone
plz give me some hint? Thanks a lot
ginger
