NAME

visual/filter - visual and filter files used with dbedit(1)

SYNOPSIS

.visual

.filter

DESCRIPTION

When dbedit(1) is asked to pop into 'visual' (or 'filter') mode on a field, a .visual (or .filter ) file is found, and the contents of the file are used as a command the UNIX system will execute.

Alternately, the standard UNIX environment variable EDITOR can be used to override the .visual file.

This feature allows different people to customize the editor that dbedit(1) will default to when asked to go into its visual mode. For example, some users may prefer edit(1) to vi(1).

The search path is the same as that for the company name file: First the working directory is searched. Then the users PATH is searched, and finally, the FirstBase home directory is searched -- all looking for a file named .visual (or .filter).

A disabling lock can be placed to disable these features as well. This is accomplished by placing an empty file named .visual_lck (or .filter_lck) somewhere along the same search path. If this lock file exists, then the requested command is not allowed to run.

Since the FIRSTBASEHOME environment variable can be used to tune the actual FirstBase home directory, a hardwired directory, /usr/lib/firstbase, is always searched for these lock files.

Note that the same locking mechanism is used to keep users from starting up sub-processes from within dbedit(1). This lock is the .cshell_lck.
