OSXFAQ Daily Unix Tricks
Week 49 - 'find' and 'xargs' (30 June 2003)
by
Adrian Mayo - Senior Editor for Mac OS X Unix
Friday - Filenames With Spaces
If filenames have spaces, the 'find | xargs' combination will fail...
% ls -1
a file name.doc
b file name.doc
% find . -iname "*.doc" | xargs grep -il "Dear Sirs"
grep: ./a: No such file or directory
grep: file: No such file or directory
grep: name.doc: No such file or directory
grep: ./b: No such file or directory
grep: file: No such file or directory
grep: name.doc: No such file or directory
Use option '-print0' with 'find'. 'find' will print the pathname of the current file, followed by an ASCII NUL character (character code 0). Next, use option '-0' with 'xargs' so it will use NUL (``\0'') instead of whitespace as the argument separator.
% find . -iname "*.doc" -print0 | xargs -0 grep -il "Dear Sirs"
./a file name.doc
