FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

Shell builtin commands are commands that can be executed within the run‐ ning shell’s process. Note that, in the case of csh(1) builtin commands, the command is executed in a subshell if it occurs as any component of a pipeline except the last. If a command specified to the shell contains a slash “/”, the shell will not execute a builtin command, even if the last component of the speci‐ fied command matches the name of a builtin command. Thus, while specify‐ ing “echo” causes a builtin command to be executed under shells that sup‐ port the builtin echo command, specifying “/bin/echo” or “./echo” does not. While some builtin commands may exist in more than one shell, their oper‐ ation may be different under each shell which supports them. Below is a table which lists shell builtin commands, the standard shells that sup‐ port them and whether they exist as standalone utilities. Only builtin commands for the csh(1) and sh(1) shells are listed here. Consult the appropriate manual page for details on the operation of any given builtin command under those shells. Users of other shells will need to consult the documentation supplied with the other shells.
