DESCRIPTION
If directory is not specified, the value of shell parameter is used as the new working directory. If directory specifies a complete path
starting with or directory becomes the new working directory. If neither case applies, tries to find the designated directory relative to
one of the paths specified by the shell variable. has the same syntax as, and similar semantics to, the shell variable. must have execute
(search) permission in directory.
exists only as a shell built-in command because a new process is created whenever a command is executed, making useless if written and pro-
cessed as a normal system command. Moreover, different shells provide different implementations of as a built-in utility. Features of as
described here may not be supported by all the shells. Refer to individual shell manual entries for differences.

alone command is to obtain the exit status of the command.

Environment Variables
The following environment variables affect the execution of
The name of the home directory,

A colon-separated list of pathnames that refer to directories.
If the directory operand does not begin with a slash character, and the first component is not dot or dot-dot, searches
for directory relative to each directory named in the variable, in the order listed. The new working directory is set
to the first matching directory found. An empty string in place of a directory pathname represents the current direc-
tory. If is not set, it is treated as if it was an empty string.
EXAMPLES
Change the current working directory to the directory from any location in the file system:
Change to new current working directory residing in the current directory:
or
Change to directory residing in the current directory's parent directory:
