Text Processing Examples: Real Scenarios

Real-world text processing. Logs. Configs. Data. Examples.

Here's the thing: Examples show how to use tools. Learn from them.

Parse Logs​

grep "ERROR" log.txt | awk '{print $1, $5}'

My take: Parse logs with grep and awk. Common pattern.

Extract Data​

cut -d, -f1,3 data.csv | sort

My take: Extract and sort. Common pattern.

Count Occurrences​

grep "pattern" file.txt | wc -l

My take: Count with grep and wc. Simple.

Common Patterns​

Process Logs​

grep "ERROR" log.txt | awk '{print $1}' | sort | uniq -c

What's Next?​

Now that you understand examples, you can process text. Or review Text Processing to reinforce.

Personal note: Examples helped me learn. Then I adapted them. Now I use patterns from examples. They're useful. Learn from them.
