softlimit(8)           DragonFly System Manager's Manual          softlimit(8)


NAME

       softlimit - runs another program with new resource limits.


SYNOPSIS

       softlimit [ opts ] child


DESCRIPTION

       opts is a series of getopt-style options.  child consists of one or
       more arguments.

       softlimit sets soft resource limits as specified by opts.  It then runs
       child.


OPTIONS

       In each of the following opts, n may be =, indicating that the soft
       limit should be set equal to the hard limit.

       opts controlling memory use:

       -m n   Same as -d n -s n -l n -a n.

       -d n   Limit the data segment per process to n bytes.

       -s n   Limit the stack segment per process to n bytes.

       -l n   Limit the locked physical pages per process to n bytes. This
              option has no effect on some operating systems.

       -a n   Limit the total of all segments per process to n bytes. This
              option has no effect on some operating systems.

       -o n   Limit the number of open file descriptors per process to n.
              This option has no effect on some operating systems.

       -p n   Limit the number of processes per uid to n.

       opts controlling file sizes:

       -f n   Limit output file sizes to n bytes.

       -c n   Limit core file sizes to n bytes.

       Efficiency opts:

       -r n   Limit the resident set size to n bytes. This limit is not
              enforced unless physical memory is full.

       -t n   Limit the CPU time to n seconds. This limit is not enforced
              except that the process receives a SIGXCPU signal after n
              seconds.
