Piping / Executing

I've got a file with lots of commands I want to run in it. They're formatted like so:

cp /path/to/file /path/to/new/file
and on and on and on.

Hundreds of them.

Anyways, I'd like to execute them one at a time, then check what time it is, and repeat this process until 7am.

I can isolate single lines without much trouble using this command:

head +$num <file> | tail -$num

(num being the number of files that have been copied so far, initialized to 1)

...but that only outputs the command I want to execute, it doesn't actually run it, obviously.

So how do I go about executing that command? Or is there an easier way to go about it?

NAME
incm - Incorporating new mails for Mew SYNOPSIS
incm [options] DESCRIPTION
The incm utility incorporates new mails from the mbox or the maildir to Mew's inbox folder. The options are as follows: -a Retrieve all mails from maildir/{cur,new} for maildir. -b Backup mails. mbox: No truncate mbox file. maildir: To maildir/cur directory. -c Use the Content-Length: field, instead of the "From " line, as a mail separator for mbox. -d path Path to mbox/maildir. If path is a file, mbox is assumed. If path is a directory, maildir is assumed. -m path The same as the -d option. -s Read one mail from stdin instead of mbox/maildir. -i inboxdir A path to the inbox directory. -u Don't touch ".mew-mtime". -f Preserve Unix From (Envelope Sender) line in mbox case. -p mode Specify file mode that creates in mbox case. -o Use the suffix when creating messages. -x suffix Use this suffix. -h Display this help message. -v Display the version. mbox For mbox, the mail separator is "From " in the beginning of lines. The incm utility does not convert ">From " to "From " in the beginning of lines in the body. On Solaris, Content-Length: should be used with the -c option to tell the end of mail. To lock mbox, a lock file("<user>.lock"), flock() or lockf(), and open(O_EXLOCK) are used. maildir For maildir, no lock and no separator are necessary. Consider the following situation: cur/{1,2} new/{3,4} Executing incm without the options results in: cur/{1,2} new/{} to inbox: {3,4} Executing incm with the -a option results in: cur/{} new/{} to inbox: {1,2,3,4} Executing incm with the -b option results in: cur/{1,2,3,4} new/{} to inbox: {3,4} Executing incm with the -a option and the -b option results in: cur/{1,2,3,4} new/{} to inbox: {1,2,3,4} So, if both options are specified, messages are retrieved multiple times.
