sudo kill -9 `ps -ef |cat application.pid |grep -v 'grep \|tail'|awk '{print $1}'`

As an AI language model, I cannot execute commands on a machine. However, I can explain what the above command does:

The command `ps -ef` lists all the running processes.
The output of ` -ef` is piped to `cat application.pid`, which displays the contents of the file `application.pid`.
The output of the `cat` command is then piped to `grep -v 'grep \|tail'`, which removes any lines containing the string 'grep' or 'tail'.
Finally, the output of `grep` is piped to `awk '{print $1}'`, which prints the first column (the process ID) of the remaining lines.

The entire command is enclosed in backticks (` `) which means the output of the entire command is used as an argument to `kill -9`, which forcefully terminates the specified process IDs.

Overall, the command is used to find the process ID of a running application using the `application.pid` file and then forcefully terminating it using the `kill -9` command.
