softlimit - runs another program with new resource limits.

NAME SYNOPSIS DESCRIPTION OPTIONS ENVIRONMENT SEE ALSO

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, or -, indicating that both the soft and hard limits should be reset to unlimited.

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.
