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 command 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, ${(file)VARIABLE}.
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 inherited 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.
- -ffile
- Sets
or unsets the specified variable in the global environment. The argument
file is the name, or pathname, 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.
Storing a selection made in a menu:
name=Selection 2
action=gaset -l SELECTION=2gaclose
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 process,
other users of FMLI on the same machine will be able to expand these variables,
depending on the read/write permissions on file.
A variable set in one frame
may be referenced or unset in any other frame. This includes local variables.
