Scenario

The server is consuming excessive resources. This server is used by multiple teams with their own credentials (e.g. each team has a username dev-team, qa-team, ops-team etc).

Task

Identify which user is running the most number of processes (count) on the server, regardless of CPU or memory usage, and write that username to: /home/devops/solution.txt

Example

A single username written to the expected output file.

<username>

Step 1: Count processes per user

ps aux | awk '{print $1}' | sort | uniq -c | sort -rn

Step 2: Identify the user with the highest count

Look at the first line, the number is process count, the text is username

Ignore the root user, we are supposed to look for dev-team, qa-team and ops-team

Finally, write that username to solution file

echo "<username>" > /home/devops/solution.txt
