The documentation uses the following conventions for commands, filenames, and other program-specific subjects.
It will also indicate other literal bits of text from a program, such as filenames or source code.
Important:
‘#’
indicates a command prompt in most documentation; a command prompt, depending
on the system in use and the program’s tool, may actually be ‘%’
or ‘$’
or ‘(gdb)’.
For instance, the documentation may read “To delete the file named filename, type rm filename.” filename stands for the file you want to substitute, according to its name.
The Ctrl key and the Meta key are often indicated in the text by C- and M-, respectively. In addition, Meta (or M-) may indicate, for example, the Alt key on a DOS/Windows keyboard, or a diamond key on some Unix keyboards.
The ENTER (carriage return) key on your keyboard may appear as ENTER or Ret (for return).
