You could open both at once, perhaps, using open() instead of backticks. How about this:
It doesn't read from them from the same time, but if the amount of data is smaller than 64 kilobytes, buffering should let the network communication happen simultaneously anyway. When you finish one, data may already be waiting for you on the second.
The chomp is to remove linefeeds and such, since unlike backticks open() doesn't do that for you. You just get a stream.
Running a handful of these at once is fine. Trying to run hundreds at once is not recommended.
I understand that in order to run basic unix commands I would normally type at the prompt, I would have to use the following format

or
exec(ls -l);
But when I actually try to use the command, the script fails to compile and keeps telling me there is an error with this line. ... (1 Reply)

NAME
installsieve - user utility for managing sieve scripts
SYNOPSIS
installsieve
DESCRIPTION
installsieve is a utility that allows users to manage their sieve scripts kept on the server.
OPTIONS -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.
-l List all of the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
script.
-p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.
-i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten. Upon sucessfully
putting the script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
sieve names may not contain a '.'.
-a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..
-d <name> Delete the sieve script on the server with <name>.
-m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.
-g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already exists it is
overwritten.
-u <user> Userid/Authname to use for authentication; by default, the current user.
