Execution Patterns

Simple -exec with \; — one invocation per file

find ~/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/partials -name "*.adoc" -type f \
  -exec head -1 {} \;

Batch -exec with + — one invocation, many files (faster)

find ~/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/pages -name "*.adoc" -type f \
  -exec wc -l {} +

-exec sh -c for complex commands — grep first line for missing :description:

find ~/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/pages -name "*.adoc" -type f \
  -exec sh -c '
    for f; do
      if ! head -5 "$f" | grep -q ":description:"; then
        echo "MISSING :description: — $f"
      fi
    done
  ' _ {} +

Prune a directory — skip .git entirely

find ~/atelier/_bibliotheca/domus-captures -path '*/.git' -prune -o -name "*.adoc" -type f -print

Prune multiple directories

find ~/atelier/_bibliotheca/domus-captures \
  \( -path '*/.git' -o -path '*/node_modules' -o -path '*/build' \) -prune \
  -o -type f -name "*.adoc" -print | head -20

-print0 to xargs — null-delimited for spaces in filenames

find ~/atelier/_bibliotheca/domus-captures/docs -name "*.adoc" -type f -print0 | \
  xargs -0 wc -l | tail -1

xargs with parallel execution — 4 workers

find ~/atelier/_bibliotheca/domus-captures/docs -name "*.adoc" -type f -print0 | \
  xargs -0 -P4 -I{} head -1 {}

-delete — remove empty files (safer than rm)

# Dry run first — just list what would be deleted
find /tmp -name "*.tmp" -empty -type f -print

# Then delete
# find /tmp -name "*.tmp" -empty -type f -delete

Copy found files to a staging directory

mkdir -p /tmp/find-staging
find ~/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/partials/codex/find \
  -name "*.adoc" -type f -exec cp {} /tmp/find-staging/ \;
ls /tmp/find-staging/

-exec with \; vs + — timing comparison

# Slow — spawns grep once per file
# find /etc -name "*.conf" -exec grep -l "Port" {} \;

# Fast — spawns grep once with all files
find /etc -name "*.conf" -type f -exec grep -l "Port" {} + 2>/dev/null
