Null-Delimited

Standard -print0 | xargs -0 pattern — list all .adoc files safely

find /home/evanusmodestus/atelier/_bibliotheca/domus-captures/docs -name '*.adoc' -print0 \
  | xargs -0 ls -l

Count lines across files safely

find /home/evanusmodestus/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/partials/codex \
  -name '*.adoc' -print0 \
  | xargs -0 wc -l

Safe rm — delete temp files with spaces in names

# Setup: create files with spaces
mkdir -p /tmp/xargs-demo
touch /tmp/xargs-demo/"file one.txt" /tmp/xargs-demo/"file two.txt"
# Safe delete
find /tmp/xargs-demo -name '*.txt' -print0 | xargs -0 rm -v

Safe grep across files

find /home/evanusmodestus/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/pages \
  -name '*.adoc' -print0 \
  | xargs -0 grep -l 'include::partial'

Why whitespace breaks without -0 — demonstration

# Create files with spaces
mkdir -p /tmp/xargs-demo
touch /tmp/xargs-demo/"my file.txt" /tmp/xargs-demo/"your file.txt"
# WRONG — xargs splits on whitespace, treats "my" and "file.txt" as separate args
find /tmp/xargs-demo -name '*.txt' | xargs ls -l
# CORRECT — null-delimited preserves full path as one argument
find /tmp/xargs-demo -name '*.txt' -print0 | xargs -0 ls -l

Null-delimited from grep -lZ (--files-with-matches --null)

grep -rlZ 'xref:' /home/evanusmodestus/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/pages \
  | xargs -0 wc -l

Null-delimited sort for safe pipeline chaining

find /home/evanusmodestus/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/pages \
  -name '*.adoc' -print0 \
  | sort -z \
  | xargs -0 -n1 basename

Safe chmod across directories

find /home/evanusmodestus/atelier/_bibliotheca/domus-captures/docs -type d -print0 \
  | xargs -0 ls -ld

Combine -0 with -n1 for per-file operations

find /home/evanusmodestus/atelier/_bibliotheca/domus-captures/docs/modules/ROOT/partials/codex/awk \
  -name '*.adoc' -print0 \
  | xargs -0 -n1 head -1

tr for null-delimited output from non-find sources

printf 'alpha\nbeta\ngamma\n' | tr '\n' '\0' | xargs -0 -n1 echo "item:"
