Appendix D. A Comparison of Common DOS and Linux Commands
Many
Linux commands typed at a shell prompt are similar to the commands you would
type in DOS. In fact, some commands are identical.
This appendix provides common commands used at the DOS prompt in
Windows and their counterparts in Linux. Basic examples of how the
command are used at the Linux shell prompt are also provided. Note that
these commands usually have a number of options. To learn more about each
command, read its associated man page (for example, type man
ls at the shell prompt to read about the ls
command).
