NAME

bat - process manager

Bat is started automatically. It mounts /srv/proc/ and serves one directory per running process named by its pid. Each process directory contains:

record: the program and its binds; the first line is the program's path and arguments; each following line is a bind, a link whose path is bound under its label
ns: textual representation of the process's namespace
status: 'starting', 'started', 'closing'; 'err' if it failed
err: the reason for failure when status is 'err'
fs/: program's own files
ctl: 'close' ends the process

To start a process, put a record to /srv/proc/new, get the new path back.

To restart pid, put a record to /srv/proc/pid/.

To kill a process, del /srv/proc/pid/.

Start an anonymous process, get the path to its directory back:

p = req('put', '/srv/proc/new', '/bin/cons')

req('put', p, '/bin/cons') // restart
req('del', p)              // kill

Start a named process:

req('put', '/srv/proc/cons', '/bin/cons')

req('put', '/srv/proc/cons', '/bin/cons') // restart
req('del', '/srv/proc/cons')              // kill
