phpseclib\Net\SSH1::exec PHP Method

SSH1 Class Documentation Show file Open project: phpseclib/phpseclib

exec() public method

An SSH1 server will close the connection after a command has been executed on a non-interactive shell. SSH2 servers don't, however, this isn't an SSH2 client. The way this works, on the server, is by initiating a shell with the -s option, as discussed in the following links: {@link http://www.faqs.org/docs/bashman/bashref_65.html http://www.faqs.org/docs/bashman/bashref_65.html} {@link http://www.faqs.org/docs/bashman/bashref_62.html http://www.faqs.org/docs/bashman/bashref_62.html} To execute further commands, a new \phpseclib\Net\SSH1 object will need to be created. Returns false on failure and the output, otherwise.
