The s6-softlimit program

s6-softlimit changes its process limits, then executes into another program.

Interface

     s6-softlimit [ -a allmem ] [ -c core ] [ -d data ] [ -f fsize ] [ -l lock ] [ -m mem ] [ -o ofiles ] [ -p proc ] [ -r res ] [ -s stack ] [ -t cpusecs ] prog...

s6-softlimit parses its options and sets process (soft) resource limits accordingly.
A value of '=' for any option means "set that limit to the hard limit".
Depending on your operating system, an option may do nothing.
When s6-softlimit has modified all the limits successfully, it executes into prog....

Options

-a allmem : limit the total available memory to allmem bytes.
-c core : limit the core file size to core bytes.
-d data : limit the available heap memory to data bytes.
-f fsize : limit the file size to fsize bytes.
-l lock : limit the available locked memory to lock bytes.
-m mem : limit all types of memory to mem bytes.
-o ofiles : limit the number of open fds to ofiles.
-p proc : limit the number of processes to proc (per user).
-r res : limit the available physical memory to res bytes.
-s stack : limit the available stack memory to stack bytes.
-t cpusecs : limit the available CPU time to cpusecs seconds.
