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.
