NAME¶
softlimit - runs another program with new resource limits.SYNOPSIS¶
softlimit [ opts ] childDESCRIPTION¶
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.
