NAME

       svscan - starts and monitors a collection of services

SYNOPSIS

       svscan [ directory ]

DESCRIPTION

       svscan  starts  one supervise(8) process for each subdirectory of the current directory, up to a limit of
       1000 subdirectories.  svscan skips subdirectory names  starting  with  dots.   supervise(8)  must  be  in
       svscan's path.

       svscan  optionally starts a pair of supervise(8) processes, one for a subdirectory s, one for s/log, with
       a pipe between them. It does this if the name s is at most 255 bytes long and s/log exists. (In  versions
       0.70 and below, it does this if s is sticky.)  svscan needs two free descriptors for each pipe.

       Every  five  seconds,  svscan checks for subdirectories again. If it sees a new subdirectory, it starts a
       new supervise(8) process. If it sees an old subdirectory where a  supervise(8)  process  has  exited,  it
       restarts the supervise(8) process. In the log case it reuses the same pipe so that no data is lost.

       svscan is designed to run forever. If it has trouble creating a pipe or running supervise(8), it prints a
       message to stderr; it will try again five seconds later.

       If svscan is given a command-line argument directory, it switches to that directory when it starts.
