Tell me about a challenging task you were able to solve by writing a script for a Linux system

Once, I needed to automate the collection and analysis of logs on a Linux server to identify errors and anomalies. I wrote a bash script that:

• Periodically collected logs from different directories
• Filtered lines with errors by keywords
• Generated a report with the number of errors by category
• Sent the report via email to responsible staff

This significantly reduced the time for manual analysis and allowed quick response to issues. The script was scheduled to run via cron.

Example part of the script:

#!/bin/bash

LOG_DIR="/var/log/myapp"
REPORT="/tmp/error_report.txt"

grep -i "error" $LOG_DIR/*.log > $REPORT
mail -s "Daily error report" team@example.com < $REPORT

This approach helped automate routine tasks and improve system support quality.
