|
|
.Sh SYNOPSIS
|
|
.Nm cd
|
|
.Op Ar directory
|
|
.Sh DESCRIPTION
|
|
Since
|
|
.Nm
|
|
affects the current shell execution environment, it is always provided
|
|
as a shell regular built-in.
|
|
For more information consult the manual page for the shell in use.
|
|
.Pp
|
|
The
|
|
.Ar directory
|
|
operand is an absolute or relative pathname which becomes the new
|
|
working directory.
|
|
The interpretation of a relative pathname by
|
|
.Nm
|
|
depends on the
|
|
.Ev CDPATH
|
|
environment variable (see below).
|
|
.Sh ENVIRONMENT
|
|
The following environment variables affect the execution of
|
|
.Nm :
|
|
.Bl -tag -width Ev
|
|
.It Ev CDPATH
|
|
A colon-separated list of pathnames that refer to directories.
|
|
If the
|
|
.Ar directory
|
|
operand does not begin with a slash
|
|
.Pq Ql \&/
|
|
character, and the first
|
|
component is not dot
|
|
.Pq Ql \&.
|
|
or dot-dot
|
|
.Pq Ql \&.. ,
|
|
.Nm
|
|
searches for the
|
|
.Ar directory
|
|
relative to each directory named in the
|
|
.Ev CDPATH
|
|
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
|
|
directory.
|
|
If the new working directory was derived from
|
|
.Ev CDPATH ,
|
|
it will be printed to the standard output.
|
|
.It Ev HOME
|
|
If
|
|
.Nm cd
|
|
is invoked without arguments and the
|
|
.Ev HOME
|
|
environment variable exists and contains a directory name, that directory
|
|
becomes the new working directory.
|
|
.It Ev OLDPWD
|
|
Set to the previous working directory after a directory change.
|
|
Not supported by
|
|
.Xr csh 1 .
|
|
.It Ev PWD
|
|
Set to the current working directory.
