OSXFAQ Mac OS X UNIX Tip-of-the-Day
Week 98 - Spaces in Filenames (7 February 2005)
by
Adrian Mayo - Editor, OSXFAQ
Tuesday - Find, Xargs, and Spaces
'Find' is a command often used to root out particular files in a directory hierarchy and process each file, often by passing the filenames to 'xargs'.
However, it will fail for filenames with spaces:
$ ls -1 file*
file one
file two
$ find . -name "file*" | xargs ls -l
ls: ./file: No such file or directory
ls: one: No such file or directory
ls: ./file: No such file or directory
ls: two: No such file or directory
Fix this using the '-print0' option of 'find', and the '-0' option of 'xargs'.
$ find . -name "file*" -print0 | xargs -0 ls -l
-rw-r--r-- 1 saruman saruman 0 Feb 7 14:34 ./file one
-rw-r--r-- 1 saruman saruman 0 Feb 7 14:34 ./file two
'-print0' tells 'find' to null-separate filenames when it produces the list of found files, instead of space-separating them. '-0' tells 'xargs' to expect null-separated filenames.
