1 directory, 1 file

$ find . -type f | xargs grep "koala"
grep: ./te: No such file or directory
grep: st/a.txt: No such file or directory

原因

就是因为文件或目录包含空白符

$ man find
     -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).

     -X      Permit find to be safely used in conjunction with xargs(1).  If a file name contains any of the delimiting characters used by
             xargs(1), a diagnostic message is displayed on standard error, and the file is skipped.  The delimiting characters include single
             (`` ' '') and double (`` " '') quotes, backslash (``\''), space, tab and newline characters.

             However, you may wish to consider the -print0 primary in conjunction with ``xargs -0'' as an effective alternative.

$ man xargs 
     -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).

解决方案

1
$ find . -type f -print0 | xargs -0 grep --color -In "koala"

备注

Linux 的 find 命令支持 -printf 参数，而 MAC 因为是继承自 FreeBSD ，所以没有此参数，如果只考虑 Linux ，可用命令：

1
find -path "*/.svn" -prune -o -printf "\"%p\"\n" | xargs grep --color -In "engine-ie-button"

小技巧

find 命令还支持正则表达式，例如

1
-regex ".*.\(css\|js\|html\)"

References

find lacks the option -printf, now what?
Why does grep print out “No such file or directory”?
