The export Command

The export command sets and/or exports variables to the environment. It is equivalent to typeset –x, except when used within functions. Here, the PATH variable is set and exported:

					$ export PATH=$PATH:/usr/5bin
				

Multiple variables can be given to the export command. In this example, the variables A, B, C, and D are set and/or exported:

					$ export A B=1 C D=2
				

If no arguments are specified, the export command lists the names and values of exported variables:

					$ export
					EDITOR=vi
					HOME=/home/anatole
					LOGNAME=anatole
					PATH=/usr/bin:/usr/ucb:/usr/etc:/usr/5bin:
					PWD=/home/anatole/asp/pubs/ksh/v2
					SHELL=/bin/ksh
					TERM=sun
					USER=anatole
