Synopsis
export [options

] [name
=[value
]].
..
Pass (export) the value of one or more shell
variables
, giving global meaning to the
variables (which are local by default). For example, a variable
defined in one shell script must be exported if its value will be
used in other programs called by the script. When a shell variable
has been exported, you can access its value by referencing the
equivalent environment variable. If no
variables
are given, export lists the
variables exported by the current shell. If
name
and value
are specified, export assigns value
to a
variable name
and exports it.
Options
- —
Treat all subsequent strings as arguments, not options.
- -f
Expect variables to be functions.
- -n
Unexport variable.
- -p
List variables exported by current shell.
