132.Sh DESCRIPTION
133Shell builtin commands are commands that can be executed within the
134running shell's process.
135Note that, in the case of
136.Xr csh 1
137builtin commands, the command is executed in a subshell if it occurs as
138any component of a pipeline except the last.
139.Pp
140If a command specified to the shell contains a slash
141.Dq \&/ ,
142the shell will not execute a builtin command, even if the last component
143of the specified command matches the name of a builtin command.
144Thus, while specifying
145.Dq Ic echo
146causes a builtin command to be executed under shells that support the
147builtin echo command,
148specifying
149.Dq Pa /bin/echo
150or
151.Dq Pa ./echo
152does not.
153.Pp
154While some builtin commands may exist in more than one shell, their
155operation may be different under each shell which supports them.
156Below is a table which lists shell builtin commands, the standard shells
157that support them and whether they exist as standalone utilities.
158.Pp
159Only builtin commands for the
160.Xr csh 1
161and
162.Xr sh 1
163shells are listed here.
164Consult the appropriate manual page for
165details on the operation of any given builtin command under those shells.
166Users of other shells will need to consult the documentation supplied
167with the other shells.
