Linux Commands: Enable and disable builtin shell commands.


enable-Linux Command

enable

Enable and disable builtin shell commands.

SYNTAX
        enable [-n] [-p] [-f filename] [-ads] [name ...]

OPTIONS
      -a     list each builtin with an indication of whether or not 
             it is enabled.
  
      -d      Delete a builtin loaded with `-f'. 

      -f     load the new builtin command name from shared object filename, 
             on systems that support dynamic loading.

      -n     Disable the names listed, otherwise names are enabled.

      -p     Print a list of shell builtins, default if no name arguments appear
             With no other arguments, the list consists of all enabled shell builtins. 

      -s     Restrict to enable only POSIX special builtins

Disabling a builtin allows a disk command which has the same name as a shell builtin to be executed without specifying a full pathname, even though the shell normally searches for builtins before disk commands.

For example, to use the test binary found via $PATH instead of the shell builtin version, type `enable -n test'.

If there are no options, a list of the shell builtins is displayed.

If `-s' is used with `-f', the new builtin becomes a special builtin.

The return status is zero unless a name is not a shell builtin or there is an error loading a new builtin from a shared object.
