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:
−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. |
