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.
