The export Command





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
