.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.
2024-08-22 09:24:12 -04:00
.Sh BUGS
.Nm
lacks escape characters, meaning arguments with special characters
.Em must
be enclosed in quotes.
