Set an environment variable. Mark each name to be passed to child processes in the environment.

SYNTAX
export [-fn] [-p] [name[=value]]

OPTIONS
-f The names refer to shell functions;
otherwise the names refer to shell variables
-n No longer mark each name for export.
-p Display output in a form that may be reused as input.
If no names are supplied, or if the `-p'' option is given, a list of exported names is displayed.

The return status is zero unless an invalid option is supplied, one of the names is not a valid shell variable name, or `-f'' is supplied with a name that is not a shell function.

export is a BOURNE shell command and a POSIX `special'' builtin.

Example - local variables

old_file=export.csv
new_file=last.csv
mv $old_file $new_fileExample - global variables

mydepartment=Sales ; export mydepartment
mycustomer=''Brown Brothers'' ; export mycustomer
