Comparison of Common DOS and Linux Commands

After a 2 day exercise in trying to rebuild a virus ridden Asus K55A laptop with no recovery drive or disk for it, which introduced the horror of the Win8 BIOS encrypted install key (Post on it soon), I thought it was time to learn more Win cmds to match some common Linux ones, so start with this close equivalents list from Redhat, then expand as I find more, or formats that do the same task:

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).

Notes:a. Gedit is a graphical text editor; other editors you can use in place of Gedit include nano and vi.
b. The more pager can also be used to page through a file one screen at a time.
c. The mv command can both move a file and, if you want to rename a file in the same directory, "move" that file to the same directory with a new name.
