How do I manage files with spaces and newlines when using find on linux?

When you passing the output of find to another command, some filenames have spaces and newlines. Using the right find options can help produce the correct results.
Out find directory contains the following. One file has spaces.
$ ls biff bigfile2 fileb int 'Users on system' bigfile filea filex test
We are looking for a word in one of the files. A normal find produces this output. The file "Users on systems", is taken as three separate files because of the spaces.
$ find . -type f -print | xargs grep Perm grep: ./Users: No such file or directory grep: on: No such file or directory grep: system: No such file or directory
-0to xargs. It grep found a match in our file with spaces.
$ find . -type f -print0 | xargs -0 grep Perm ./Users on system:Permissions are here.
-print0 True; print the full file name on the standard output, followed by a null character (instead of the newline character that -print uses). This allows file names that contain newlines or other types of white space to be correctly interpreted by pro‐ grams that process the find output. This option corresponds to the -0 option of xargs.
-0, --null Input items are terminated by a null character instead of by whitespace, and the quotes and backslash are not special (every character is taken literally). Disables the end of file string, which is treated like any other argument. Useful when input items might contain white space, quote marks, or backslashes. The GNU find -print0 option produces input suitable for this mode.
