Set an environment variable. The supplied names are marked for automatic export to the environment of subsequently executed commands.
Syntax
export [-fn] [name[=word]] ...
export -p
Key
-f The names refer to functions.
word The value of the variable is set to word.
-n Remove the export property from each name.
-p Print a list of all the names exported in this shell.
This is also the default action if no name is given
export returns an exit status of 0 unless an invalid option is encountered, one of the names is not a valid shell variable name, or -f is supplied with a name that is not a function.
export is a bash built in command. (in tcsh you would use setenv instead)
