Hi,I wanna execute an external bash command but timeout if it's taking longer than XX seconds. I've tried it like this: eval { local $SIG{ALRM} = sub {die "alarm\n"}; alarm $timeout; $test = `$sshpassPATH . " -p ".$clientpw." ssh root@".$ip." ". $RemcksumPATH." ".$RemcksumPATH." > ".$ckCKSUMclt`;
Backquotes `` create a double-quote context. You cannot use double-quotes or the concatenate operator . within that context. Put your command-line in a variable:
my $cmd = "$sshpassPATH -p ..." and then print the command to see what you are really trying to execute: print "cmd: <$cmd>\n"; and then execute it; $test = `$cmd`; -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
