1 /* ulimit.c - Modify resource limits
8  * Deviations from posix: The units on -f are supposed to be 512 byte
9  * "blocks" (no other options are specified, and even hard drives don't
13  * Deviations from bash: Sizes are in bytes (instead of -p 512 and -f 1024).
14  * Bash's -p value has been wrong since 2010 (git 35f3d14dbbc5).
15  * The kernel implementation of RLIMIT_LOCKS (-x) was removed from Linux in
16  * 2003. Bash never implemented -b (it's in the help but unrecognized at
17  * runtime). We support -P to affect processes other than us.

27     usage: ulimit [-P PID] [-SHRacdefilmnpqrstuv] [LIMIT]
29     Print or set resource limits for process number PID. If no LIMIT specified
30     (or read-only -ap selected) display current value (sizes in bytes).
31     Default is ulimit -P $PPID -Sf" (show soft filesize of your shell).
33     -S  Set/show soft limit          -H  Set/show hard (maximum) limit
34     -a  Show all limits              -c  Core file size
35     -d  Process data segment         -e  Max scheduling priority
36     -f  Output file size             -i  Pending signal count
37     -l  Locked memory                -m  Resident Set Size
38     -n  Number of open files         -p  Pipe buffer
39     -q  Posix message queue          -r  Max Real-time priority
40     -R  Realtime latency (usec)      -s  Stack size
41     -t  Total CPU time (in seconds)  -u  Maximum processes (under this UID)
42     -v  Virtual memory size          -P  PID to affect (default $PPID)
52 // This is a linux kernel syscall added in 2.6.36 (git c022a0acad53) which
57 // I'd like to sort the RLIMIT values 0-15, but mips, alpha and sparc
58 // override the asm-generic values for 5-9. Also, the kernel implementation
59 // of RLIMIT_LOCKS (-x) was removed from Linux in 2003.
