set, unset - set and unset local or global environment vari-
set [ -l variable [ =value]] ...
set [ -e variable [ =value]] ...
set [ -ffile variable [ =value]...] ...
unset -l variable...
unset -f file variable...
The set command sets variable in the environment, or adds
variable=value to file. If variable is not equated it to a
value, set expects the value to be on stdin. The unset com-
mand removes variable. Note that the FMLI predefined, read-
only variables (such as ARG1), may not be set or unset.
Note that at least one of the above options must be used for
each variable being set or unset. If you set a variable with
the -ffilename option, you must thereafter include filename
in references to that variable. For example,
FMLI inherits the UNIX environment when invoked.
-l Sets or unsets the specified variable in the local
environment. Variables set with -l will not be inher-
ited by processes invoked from FMLI.
-e Sets the specified variable in the UNIX environment.
Variables set with -e will be inherited by any
processes started from FMLI. Note that these variables
cannot be unset.
Sets or unsets the specified variable in the global
environment. The argument file is the name, or path-
name, of a file containing lines of the form
variable=value. file will be created if it does not
already exist. Note that no space intervenes between
-f and file.
Example 1: A sample output of set command.
Storing a selection made in a menu:
action=`set -l SELECTION=2`close
Variables set to be available to the UNIX environment (those
set using the -e option) can only be set for the current
fmli process and the processes it calls.
When using the -f option, unless file is unique to the pro-
cess, other users of FMLI on the same machine will be able
to expand these variables, depending on the read/write per-
missions on file.
A variable set in one frame may be referenced or unset in
any other frame. This includes local variables.
