144.Sh DESCRIPTION
145Shell builtin commands are commands that can be executed within the
146running shell's process.
147Note that, in the case of
148.Xr csh 1
149builtin commands, the command is executed in a subshell if it occurs as
150any component of a pipeline except the last.
151.Pp
152If a command specified to the shell contains a slash
153.Dq \&/ ,
154the shell will not execute a builtin command, even if the last component
155of the specified command matches the name of a builtin command.
156Thus, while specifying
157.Dq Ic echo
158causes a builtin command to be executed under shells that support the
159.Nm echo
160builtin command,
161specifying
162.Dq Ic /bin/echo
163or
164.Dq Ic ./echo
165does not.
166.Pp
167While some builtin commands may exist in more than one shell, their
168operation may be different under each shell which supports them.
169Below is a table which lists shell builtin commands, the standard shells
170that support them and whether they exist as standalone utilities.
171.Pp
172Only builtin commands for the
173.Xr csh 1
174and
175.Xr sh 1
176shells are listed here.
177Consult a shell's manual page for
178details on the operation its builtin commands.
179Beware that the
180.Xr sh 1
181manual page, at least, calls some of these commands
182.Dq built-in commands
183and some of them
184.Dq reserved words .
185Users of other shells may need to consult an
186.Xr info 1
187page or other sources of documentation.
