ripgrep for searching
ripgrep searches trees fast by default: recursive, respects ignore files, regex-native. It complements grep rather than replacing the POSIX toolkit.
Everyday invocations
rg ERROR /var/log/app.log # simple search
rg -i todo ~/src/ # case-insensitive recursive
rg -l 'Listen 80' /etc/ # filenames only
rg -C2 NotFound service.log # 2 lines context each side
rg -uu hidden_feature # include ignored/hidden anywayResults arrive fast enough to iterate hypotheses interactively rather than batching queries cautiously.
Combining with pipelines
rg 'Cache-Control' nginx/*.conf | awk '{print $3}' | sort | uniq -cStill respecting grep
grep remains POSIX-portable and universally available in minimal images; rg excels locally and interactively. Knowing both avoids either disappointment.
| grep idiom | rg equivalent |
|---|---|
| grep -rn pattern dir/ | rg pattern dir/ |
| grep -i | rg -i |
| grep -E | rg (native) |
| grep -B2 -A4 | rg -B2 -A4 |
Prove it works: search integration habitual
reaching for rg without hesitation when answering 'where is X configured?' — reflex indicates adoption complete.
