from the man file:
export [-fn] [name[=word]] ...
export -p
The supplied names are marked for automatic export to
the environment of
subsequently executed commands. If the -f option
is given, the names
refer to functions. If no names are given, or if the -p
option is sup-
plied, a list of all names that are exported in this
shell is printed.
The -n option causes the export property to be removed
from each name. If
a variable name is followed by =word, the value of the
variable is set to
word. 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.
but it doesn't say which files are effected by the command. is it stored somewhere?
No files are affected by the command. All it does is mark a shell variable as being an environment variable that is passed on to any subsequent commands you execute *from that shell*.
