NAME
       sched - a way to repetitively invoke a command

SYNOPSIS
       sched [-r<repetitions>] [-t<seconds>] "shell command"

DESCRIPTION
       sched  causes  the  command  typed in quotes to be repetitively
       invoked. The defaults are to invoke the command  once,  and  to
       wait  1  second  before each invocation.  This utility is quite
       nice for statistics gathering, since sched may be  run  in  the
       background,  with  the diagnostic output being appended to some
       log file.  For example:
       
       % sched -r360 -t10 "pip t.=[105,3]/tb; cat t >>tmp.log; rm t"
       
       would generate a log file of the disk space in use in the tools
       tmp directory, running every ten seconds for the next hour. The
       resulting log file could then be scanned to see  how  the  disk
       usage fluctuates, edited so that the information could be input
       to a histogram utility, etc.
