Re: Running a shell command via Perl

you can also run them as pipes so you can parse the output.

open (FileHandle,"cp thisFile /root/thatfile|");
@Output = <FileHandle>;

This allows you to see the output of the comand, it is good for error checking with the cp command

Thank you ALL I have it working now. I also found something else: `use Shell; my $sh = Shell->new; $tmp = $sh->exec('readlink /root/Desktop/PerlScripting/mylink '); print "$tmp";` [download] (here I run the "readlink" shell command) What is your opinion on this ? BTW, although most command work, I can't get the cd command to work (e.g - `cd /root/Desktop/perlTesting/` ) Why ?	[reply] [d/l]

Regarding the `cd /root/.... you need to use the Perl built-in `chdir` Cheers, JohnGG	[reply] [d/l] [select]

When you need to make a call for system resources try to see (or search in portuguese) if similar command are available on builtin funtions... `$ perldoc -f readlink readlink EXPR readlink Returns the value of a symbolic link, if symbolic links are implemented. If not, gives a fatal error. If there is some system error, returns the undefined value and sets $! (errno). If EXPR is omitted, uses $_.` [download] This resource is new for me, but my first try is perldoc local or via web. (the second is CPAN! ;) -- Marco Antonio Rio-PM	[reply] [d/l]
