ulimit [-SHacdflmnpstuv [limit]] Provides control over the resources available to the shell and to processes started by it, on systems that allow such control. The -H and -S options specify that the hard or soft limit is set for the given resource. A hard limit cannot be increased once it is set; a soft limit may be increased up to the value of the hard limit. If neither -H nor -S is specified, both the soft and hard limits are set. # jumps straight to the definition of ulimit in the bash man page. Show Sample Output

Trying to check for an open port and missing netcat or nmap? This is the lowest common denominator way to verify a port is accessible from one server to another. This will give you a pretty quick return of 0 if it works. If it fails, it will just hang and takes awhile to timeout. I usually ctrl+c the command. "echo ?$" will give you an exit code other then 0 after you exit. Show Sample Output
