Ubuntu fix Sudo:source:command not found error

You can see that the default number of open files is limited to 1024 by executing the following command on Ubuntu server.

$ ulimit-n

1024

Edit the/etc/profile configuration file and add a line at the end:

Ulimit-shn 65535

To have the configuration take effect:

$ sudo source/etc/profile

Sudo:source:command not found

What happens when we execute the ULIMIT-SHN 65535 command directly?

$ ulimit-shn 65535

-bash:ulimit:open Files:cannot Modify limit:operation not permitted

$ sudo ulimit-shn 65535

Sudo:ulimit:command not found

When a normal user is given root permission to prompt for no command, how to solve the problem?

$ sudo-s

# Source/etc/profile

Execute Ulimit again, and you can see that the number of open files has been changed to 65535.

# Ulimit-n

65535
