export
EXPORT(P) POSIX Programmer's Manual EXPORT(P)
NAME
export - set the export attribute for variables
SYNOPSIS
export name[=word]...
export -p
DESCRIPTION
The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the envi-
ronment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to
word.
The export special built-in shall support the Base Definitions volume of IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
When -p is specified, export shall write to the standard output the names and values of all exported variables, in the following format:
"export %s=%s
", <name>, <value>
if name is set, and:
"export %s
", <name>
if name is unset.
The shell shall format the output, including the proper use of quoting, so that it is suitable for reinput to the shell as commands that
achieve the same exporting results, except:
1. Read-only variables with values cannot be reset.
2. Variables that were unset at the time they were output need not be reset to the unset state if a value is assigned to the variable
between the time the state was saved and the time at which the saved output is reinput to the shell.
When no arguments are given, the results are unspecified.
OPTIONS
See the DESCRIPTION.
OPERANDS
See the DESCRIPTION.
STDIN
Not used.

APPLICATION USAGE
None.
EXAMPLES

export PWD HOME
Set and export the PATH variable:
export PATH=/local/bin:$PATH
Save and restore all exported variables:
export -p > temp-fileunset a lot of variables... processing. temp-file
RATIONALE
Some historical shells use the no-argument case as the functional equivalent of what is required here with -p. This feature was left
unspecified because it is not historical practice in all shells, and some scripts may rely on the now-unspecified results on their imple-
mentations. Attempts to specify the -p output as the default case were unsuccessful in achieving consensus. The -p option was added to
allow portable access to the values that can be saved and then later restored using; for example, a dot script.
FUTURE DIRECTIONS
None.
