softlimit (8)

NAME

softlimit - runs another program with new resource limits.

softlimit [ opts ] child

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.

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:

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.
