Try putting "bc" into the search box on this site.
Is it possible that you can post a clear script example that does not contain a completely pointless "sed" command.

makedev.local
MAKEDEV.LOCAL(8) BSD System Manager's Manual MAKEDEV.LOCAL(8)
NAME
MAKEDEV.local -- create site-specific device special files
SYNOPSIS
MAKEDEV.local [-fMsu] [-m mknod] [-p pax] [-t mtree] {all | site-specific-argument} [...]
DESCRIPTION
MAKEDEV.local is used to create site-specific device special files. Each argument may be the word all or a site-specific argument. By
default, there are no valid site-specific arguments, and the all argument has no effect; This may be changed by editing the script.
The script is in /dev/MAKEDEV.local. Devices are created in the current working directory; in normal use, MAKEDEV.local should be invoked
with /dev as the current working directory.
Supported options for MAKEDEV.local are the same as for MAKEDEV(8).
FILES
/dev special device files directory
/dev/MAKEDEV script that invokes MAKEDEV.local with the all argument.
/dev/MAKEDEV.local script described in this man page
SEE ALSO
config(1), intro(4), MAKEDEV(8), mknod(8)
HISTORY
The MAKEDEV.local command appeared in 4.2BSD. Handling of the same command line options as MAKEDEV(8), and the use of MAKEDEV(8) as a func-
tion library, was added in NetBSD 5.0.
NOTES
The relationship between MAKEDEV.local and MAKEDEV(8) is complex:
o If MAKEDEV(8) is invoked with the all or local argument, then it will invoke MAKEDEV.local as a child process, with options similar to
those that were originally passed to MAKEDEV(8), and with the all argument.
o MAKEDEV.local uses shell functions defined in MAKEDEV(8). This is done by loading MAKEDEV(8) using the shell ``.'' command, with the
MAKEDEV_AS_LIBRARY variable set (to inform MAKEDEV(8) that it should behave as a function library, not as an independent program).
