find . -print0 | xargs -0 echo: uyota 匠の一手

ディレクトリ名に0x20（空白）が入るMac OS X環境でfindに-print0を使わずにxargsで受け取るのはヤバい。

% man find
     -print  This primary always evaluates to true.  It prints the pathname of
             the current file to standard output.  If none of -exec, -ls,
             -print0, or -ok is specified, the given expression shall be
             effectively replaced by ( given expression ) -print.

     -print0
             This primary always evaluates to true.  It prints the pathname of
             the current file to standard output, followed by an ASCII NUL
             character (character code 0).

     -0      Change xargs to expect NUL (``\0'') characters as separators,
             instead of spaces and newlines.  This is expected to be used in
             concert with the -print0 function in find(1).

これは知らなかった。普段は空白を含まないから全然問題になってなかったので。
