.Sh BEHAVIORS
|
|
.Ss AUTORUN
|
|
Autorun is enabled by default, and can be disabled with the
|
|
.Fl D
|
|
flag. If enabled, the program will search registry variables
|
|
.Cd HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun
|
|
and
|
|
.Cd HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun
|
|
for commands at startup and execute them if present.
|
|
.Ss COMMAND EXTENSIONS
|
|
Command extensions are enabled by default, and can be disabled by setting
|
|
.Fl E Ns = Ns OFF .
|
|
Extensions can modify the following commands:
|
|
.Pp
|
|
.Ic DEL or Ic ERASE ,
|
|
.Ic COLOR ,
|
|
.Ic CD or Ic CHDIR ,
|
|
.Ic MD or Ic MKDIR ,
|
|
.Ic PROMPT ,
|
|
.Ic PUSHD ,
|
|
.Ic POPD ,
|
|
.Ic SET ,
|
|
.Ic SETLOCAL ,
|
|
.Ic ENDLOCAL ,
|
|
.Ic IF ,
|
|
.Ic FOR ,
|
|
.Ic CALL ,
|
|
.Ic SHIFT ,
|
|
.Ic GOTO ,
|
|
.Ic START ,
|
|
.Ic ASSOC ,
|
|
.Ic FTYPE
|
|
.Ss EXECUTION-TIME ENVIRONMENT VARIABLE EXPANSION
|
|
Execution-time environment variable expansion is disabled by default, and can be enabled by setting
|
|
.Fl V Ns = Ns OFF .
|
|
If enabled, enclosing a variable name with '!' characters will substitute the variable's value at command execution time.
|
|
.Ss FILENAME COMPLETION
|
|
Filename completion is disabled by default, and can be enabled by setting
|
|
.Fl F Ns = Ns ON .
|
|
If enabled, Ctrl-D and Ctrl-F can be used for directory and file completion respectively.
|
|
.Ss MODIFIED INPUT HANDLING
|
|
If the
|
|
.Fl S
|
|
flag is present, the program will strip the leading and trailing quotes from the
|
|
.Ar command
|
|
supplied to
|
|
.Fl C
|
|
or
|
|
.Fl K
|
|
and pass the remaining string literally as if it was typed directly into the prompt, ignoring special characters.
|
|
.Sh BUGS
|
|
.Nm
|
|
lacks escape characters, meaning arguments with special characters
|
|
.Em must
|
|
be enclosed in quotes.
