Appendix A

Going from DOS to UNIX

For more information about any of the UNIX system commands, consult the Operating System User's Reference.

The commands listed in ``Equivalent UNIX and DOS commands'' are for working with UNIX system files. If you have DOS installed on the same machine as your SCO OpenServer system, you can access your DOS files from within the UNIX system. For more information about accessing DOS files from the SCO OpenServer system, see ``Working with DOS'' or doscmd(C).

Equivalent UNIX and DOS commands

DOS		UNIX system
command	What it does	equivalent	Notes
cd	change directories	cd(C)
cls	clear the screen	clear(C)
copy	copy files	cp(C), copy(C), tar(C)	Use cp to copy files, copy to copy directories, and tar to copy files or directories onto floppy disks or tapes.
date	display the system date and time	date(C), cal(C)	On the UNIX system, date displays the date and the time. cal displays the date, the time, and a 3-month calendar.
del	delete a file	rm(C)	Be careful when using rm with wildcard characters, like rm .
dir	list the contents of a directory	ls(C)	There are a variety of options to ls including ls -l to see a long listing, ls -c to see a listing in columns, and ls -f to see a listing that indicates file types.
diskcomp	make a track-by-track comparison of two floppy disks	diskcmp(C)

diskcopy	copy a source disk to a target disk	diskcp(C)
edlin	line editor	ed(C), ex(C), vi(C)	vi is a full-screen text editor with powerful search and replace functions. ed and ex are predecessors of vi.
fc	compare two files	diff(C), diff3(C), cmp(C)	diff compares two text files. diff3 compares three text files. Use cmp to compare binary files.
find	find text within a file	grep(C)	grep (global regular expression parser) finds text within a file. The UNIX system's find(C) command finds files.
format	format a disk	format(C)	See /etc/default/format for the default drive to format. The format command formats a disk for use with UNIX system files. Use dosformat (see doscmd(C)) to format a DOS disk.
mkdir	make a directory	mkdir(C)
more	display output one screen at a time	more(C)
print	print files in the background	lp(C)	Use lp filename & to print in the background. You can run any UNIX system command in the background by adding & (ampersand) to the end of the command line.
ren	rename a file	mv(C)
rmdir	remove an empty directory	rmdir(C)	Use rm -r to remove a directory that is not empty.
sort	sort data	sort(C)
type	display a text file	cat(C), more(C)
xcopy	copy directories	copy(C), tar(C)	Use tar if you want to copy directories onto disk or tape.
