How do i open console in minecraft server

i searched a lot all people say ./mcserver console but how do i do it

The notation

./mcserver console

assumes the program mcserver is in the current working directory (cwd) of your shell. If that's not the case, the shell is going to return the error: ./mcserver: No such file or directory.

There are two ways to fix this:

1. cd to wherever mcserver is first and then run it:

cd /the/path/to/where/mcserver/lives
./mcserver console

or

1. Invoke mcserver using it's complete path:

/the/path/to/where/mcserver/lives/mcserver console
