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.
