That is not POSIX and not portable.

Never-the-less, there are still two arguments in favour of my solution:
  1. Once Linux has executed the grep executable, it remains in memory, so it takes negligible time to execute, and

The time to fork and exec an external command it still many times longer than a purely shell solution.

As can mine.

NAME

       phones - File containing the remote host phone number database

SYNOPSIS

       /etc/phones

       The /etc/phones file contains the system-wide private phone numbers for the tip(1) program.

DESCRIPTION

       This file is normally unreadable, and so may contain privileged information.  The format of the file is a series of lines of the form: sys-
       temname	 phone-number

       where systemname is defined in the /etc/remote file and phone-number is the system phone number terminated only by a comma or by the end of
       the line.  Only one phone number per line is permitted.	However, if more than one line in the file contains the same system name, tip will
       attempt to dial each one in turn, until it establishes a connection.

EXAMPLES

       The following example shows the entry in /etc/phones for the system, zeus: zeus		    9=555-9898

       In this example, the = sign (or an asterisk) forces the autocall units to pause and wait for a second dial  tone,  when	going  through	an
       exchange.  The = is required by the DF02-AC (an asterisk would be required by the BIZCOMP 1030).

RELATED INFORMATION

       Commands: tip(1).

       Files: remote(4).  delim off
