Flasher monitors changes to one or more files, and indicates the
|
|
number of writes to these files by briefly flashing a console LED
|
|
once for each write. The flashing sequence is repeated, after a
|
|
brief pause, until the files have been read. As the files are
|
|
subsequently read, the number of LED flashes is reduced. When all
|
|
monitored files have been read, the console LED will be disabled.
|
|
|
|
The most obvious use is to monitor specific system log or mail files.
|
|
|
|
Multiple LEDs can be used. Each possible LED (-c, -n or -s) takes
|
|
a list of colon-separated file arguments. For example, when invoked
|
|
as:
|
|
|
|
# ./flasher -s /var/log/messages:/var/mail/root
|
|
|
|
the Scroll Lock LED will flash once for each write made to either
|
|
of these files, until the files are read. When /var/log/messages
|
|
has been read, the Scroll Lock LED will continue to flash once for
|
|
each write that has been made to /var/mail/root, until it also has
|
|
been read.
|
|
|
|
The list of files can include files that don't yet exist.
