The power of posix_spawn in your shell.
This is a command-line utility that wraps the posix_spawn function, exposing the extra process spawning functionality to your shell. It even supports all of Apple's private API's, such as spawning a process with ASLR disabled.
Usage: posixspawn [options...] [--] [args...]
options:
-f <flags> Pipe-delimited list of flags (see flags section below).
-p <path> Set the executable path separate from arg 0.
-w Wait for child process to complete before returning?
args:
The remaining arguments are passed to the child process.
flags:
The flags arguments is a pipe-delimited list of constants or integers.
A flag can be a string constant, a base-16 string, or a base-10 string.
The flag uses the short data type, with each flag a maximum 2 bytes.
Example argument:
"EXAMPLE_CONSTANT|0xF0|16"
The following string constants are supported:
0x0001 POSIX_SPAWN_RESETIDS
0x0002 POSIX_SPAWN_SETPGROUP
0x0004 POSIX_SPAWN_SETSIGDEF
0x0008 POSIX_SPAWN_SETSIGMASK
