Positional parameters is the term you need to look for when searching. They should be documented in your shell's manual page. They are shell variables (aka parameters) of the form $1, $2 ... $N, where N is the number of arguments with which the script was called. You'll also want to learn about the related special variables $* and $@.

dosemu
DOSEMU(1) DOS Emulation DOSEMU(1)
NAME
dosemu, xdosemu - run DOS and DOS programs under Linux
SYNOPSIS
dosemu [ -dumb ] [ -quiet ] [ -input keystroke-string ] [ -s ] [ -install [ bootdir ] ] [ args ]
xdosemu [ -dumb ] [ -quiet ] [ -input keystroke-string ] [ -s ] [ -install [ bootdir ] ] [ args ]
DESCRIPTION
dosemu is the wrapper script for dosemu.bin (1) which invokes the Linux dos emulator, also known as DOSEMU. The wrapper also takes care of
(eventually) installing the private instance of DOSEMU in the user's $HOME, if this doesn't exist.
OPTIONS
args any number of options described in dosemu.bin (1), please refer to this man page for further details. However, take care to quote
and escape correctly so bash doesn't mess up arguments containing blanks and backslashes.
-dumb use `dumb' terminal mode. This will only work for DOS applications, which do plain text output to stdout, but has the advantage that
(A) the output of the DOS application stacks up in your xterm scroll buffer and (B) you can redirect it to a file such as
$ dosemu -dumb dir > listing
Note that DOSEMU command.com's commandline editor/history will also work here, however, editing is restricted to BACKSPACE'ing.
-quiet do not print startup comment and do not stop for prompting
-input Do simulated keystrokes as given by keystroke-string just after DOS has booted. This can be used to autolaunch applications, bypass
any needed boot menus or something similar. For details on the format of the string look at README.txt.
-s Invoke dosemu via sudo. This is necessary to get access to certain I/O ports and to get graphics on the Linux console. Please refer
to the documentation (INSTALL and README.txt) to see which files need to be adjusted before attempting this.
-install [ bootdir ]
launched as part of a systemwide installation, this option (re-)installs a DOS that is used in DOSEMU (this can be the DOSEMU dis-
tributed FreeDOS or any proprietary DOS, which is bootable via fatfs). bootdir is the base name of a directory. The symbolic link
~/.dosemu/drives/c will be changed to point to this directory. Re-installing is only rarely necessary, since in practise the sym-
bolic link(s) will automatically point to updated files.
--version
print version of dosemu and list of available options.
AUTHOR
DOSEMU (comprised of the files dosemu.bin and dosemu ) is based on version 0.4 of the original program written by Matthias Lautner (no cur-
rent address that I know of).
Robert Sanders <gt8134b@prism.gatech.edu> was maintaining and enhancing the incarnation of DOSEMU with which this man page was originally
distributed. During about 4 years James B. MacLean <macleajb@ednet.ns.ca> was the restless leader of the dosemu team, implementation of
DPMI (which made Windows-3.1, dos4gw, djgpp, e.t.c running) happened during his 'governement' and brought the project near to Beta-state.
Hans Lermen <lermen@fgan.de> took over and released the first 1.0 version. Now Bart Oldeman <bart@dosemu.org> is maintaining this funny
software.
