Improving .bashrc Trap Command for Bash Script

[priyanshscpp]

Problem

The .bashrc file contains the following line to append every executed command to a file:
[
[trap 'echo $BASH_COMMAND >> /workspace/project/.freeCodeCamp/test/.next_command' DEBUG]

Issues Identified:

==>File Size Growth: Appending all executed commands to the .next_command file without any limits may result in excessive file size over time.

==>Performance Impact: Continuously appending commands could lead to slower performance, especially in environments with frequent command execution.

Proposed Solution

Modify the trap command to limit the number of lines retained in the .next_command file. This ensures that the file does not grow indefinitely, mitigating performance issues and disk space usage.

trap 'echo $BASH_COMMAND >> /workspace/project/.freeCodeCamp/test/.next_command; \
      tail -n 100 /workspace/project/.freeCodeCamp/test/.next_command > /workspace/project/.freeCodeCamp/test/.next_command.tmp && \
      mv /workspace/project/.freeCodeCamp/test/.next_command.tmp /workspace/project/.freeCodeCamp/test/.next_command' DEBUG
