Filenames with spaces (or newlines) breaking your find | xargs? Use -print0

Plain find ... | xargs splits its input on whitespace, so a file called a b.log turns into two arguments, ./a and b.log. A filename with a newline in it breaks the same way. Here is what that looks like in a test folder with a b.log, a file with a newline in its name, and plain.log:

$ find . -name '*.log' | xargs ls -1
ls: cannot access './new': No such file or directory
ls: cannot access 'line.log': No such file or directory
ls: cannot access './a': No such file or directory
ls: cannot access 'b.log': No such file or directory
./plain.log

Fix 1: NUL-separated paths

A NUL byte can't appear inside a Unix path, so it's a safe separator. -print0 makes find end each path with one, and xargs -0 splits only on it:

find . -name '*.log' -print0 | xargs -0 ls -1d

Add -r (GNU xargs) if the command shouldn't run at all when nothing matches.

Fix 2: skip xargs with -exec ... +

find . -name '*.log' -exec ls -1d -- {} +

The + packs as many paths into each command as fit. One gotcha: {} has to stand alone right before the +. Writing -exec echo "x {}" + fails with "the '{}' must appear by itself".

Fix 3: a loop, when you need per-file logic

find . -name '*.log' -print0 |
while IFS= read -r -d '' f; do
  printf 'got [%s]\n' "$f"
done

-d '' reads up to each NUL, IFS= keeps leading and trailing spaces, and -r keeps backslashes.

Deleting safely

find . -name '*.log' -print0 | xargs -0 rm -f --

The -- stops a file named -rf from being read as an option. Watch out for AI-written snippets that use rm --quiet; GNU rm has no such option, and it errors out.

Every command above was run on GNU findutils and bash before I posted it.

If you like having this kind of thing on one page, I made a Linux + Git command reference.
