ULIMIT(1)

NAME

ulimit - get or set process resource limits.

SYNOPSIS

ulimit [-HS] [-cdfnstv] [limit]
ulimit [-HS] -a

DESCRIPTION

ulimit is a POSIX regular builtin provided by Rush. Without a limit operand, it prints the selected resource limit. A numeric operand sets the limit; unlimited removes it. When neither -H nor -S is given, setting a limit updates both the hard and soft limits.

OPTIONS

-H

Select the hard limit.

-S

Select the soft limit. This is the default when printing.

-a

Print all supported resource limits.

-c

Core file size, in 512-byte blocks.

-d

Data segment size, in KiB.

-f

File size, in 512-byte blocks. This is the default resource.

-n

Number of open files.

-s

Stack size, in KiB.

-t

CPU time, in seconds.

-v

Address-space size, in KiB.

EXIT STATUS

See the POSIX definition for command-specific status rules. Usage errors generally return a non-zero status.
