I'm using Bash on both client and server. When running a command over SSH:
ssh <host> 'declare'gives a list of shell variables.
ssh <host> 'mount'gives a list of mountpoints.
declare is a Bash builtin, while
mount is an external command. How does SSH know which to run if there is a shell builtin and an external command with the same name on the server?
/etc/passwd. If it's
/usr/sbin/nologinyou can't log in.
