Hello all!
I used to use expr for doing simple mathematics, but has a main advantage and a main disadvantage:
The advantage is that it can take variables for numbers

CCD2ISO(1) User Commands CCD2ISO(1)
NAME
ccd2iso - convert IMG format to ISO format
SYNOPSIS
ccd2iso [FOO.IMG] [BAR.ISO]
DESCRIPTION
ccd2iso converts FOO.IMG to ISO format and writes the result to BAR.ISO. If fewer arguments than expected are given, ccd2iso will print
its help message and quit. If more arguments than expected are given, ccd2iso will silently ignore them and use only the first two argu-
ments.
IMG files are raw-data copies of optical media, generated primarily by the Windows application CloneCD, and are primarily used to store CDs
with odd properties, such as sectors which need to have read errors when read. Conversion to ISO format removes this information, as ISO
format does not support this.
IMG files almost always include a SUB file, which contains additional data for the disc format, and a CCD file, which is a plaintext con-
figuration file describing the disc layout. ccd2iso does not make use of these files, but the applications which generate them expect them
to have the same FOO prefix as the IMG file.
LIMITATIONS
ccd2iso currently only copies the first session of multisession discs, as well as outputting a harmless warning of Unrecognized sector
mode.
ccd2iso utterly ignores the additional data in CCD or SUB files.
