Ubuntu solves the sudo: source: command not found Error

Run the following command on Ubuntu Server. The default number of opened files is 1024.

$ Ulimit-n1024

Edit the/etc/profile configuration file and add the last line:

Ulimit-SHn 65535

To make the configuration take effect:

$ Sudo source/etc/profilesudo: source: command not found

What if we directly execute the ulimit-SHn 65535 command?

$ Ulimit-SHn 65535-bash: ulimit: open files: cannot modify limit: Operation not permitted $ sudo ulimit-SHn 65535 sudo: ulimit: command not found

After obtaining the root permission, a common user prompts that the command cannot be found. How can this problem be solved?

The correct method is as follows:

$ Sudo-s # source/etc/profile

Run ulimit again. You can see that the number of opened files has changed to 65535.

# Ulimit-n65535
