cereal - client program to attach to cereal session
cereal command [args]
cereal is the client program to attach to a running cereal session.
cereal takes various subcommands:
- attach SESSION
- Attach to (take control of) cereal session SESSION. This puts the user
into a cereal console, provided by a command-restricted screen session. To
detach from an attached session, use "C-\ d". For help on other
available commands, use "C-\ ?". Cereal uses a limited instance
of screen to provide the console. See screen(1) for more info on
the available commands. `a' may be used in place of `attach'.
- follow [options] SESSION
- Follow (watch, without being able to intervene) a cereal session SESSION.
The options are: -c [--cat] to cat log instead of follow; -p [--path] to
output just the path to the log file and exit. `f' may be used in place of
- list [SESSION]...
- List session(s). With no arguments, will list all sessions. The leading
three characters in the list indicate: whether the session is running (+)
or not (-) or in some unknown state (?), whether the user can attach to
the session (a) or not (-), whether the user can follow the session (f) or
not (-). If the session state is unknown (?), it's usually because the
user asking for information about the session can't read the session stat
file. `l' may be used in place of `list'.
- Output a brief usage summary. `h' or `?' may be used in place of
Exit status is 0 if OK, 1 if minor problems, 2 if serious trouble.

If the invoking user does not have read and execute access to the cereal
session's supervise directory, `cereal list' may not always indicate that
session's status accurately.
