I noticed in the man pages for find, that the {} always have single quotes around them. find -exec '{}' \;The description states:Notice         that the braces are enclosed in single quote marks to protect them from         interpretation  as  shell  script punctuation.   The semicolon is simi-         larly protected by the use of a backslashI have never had an issue using just find -exec {} \;What is an example where the single quotes are required. 
find -exec {} vs. find -exec '{}'
bash;find
