 +
 +The -exec flag to find causes find to execute the given command once per file matched, and it will place the name of the file wherever you put the {} placeholder. The command must end with a semicolon, which has to be escaped from the shell, either as \; or as ";".
 +
 +Syntax to be used for find exec multiple commands:
 +
 +<code>find {PATH} [OPTIONS] -exec {COMMAND} {} ;</code>
 +
 +**The first argument** after the find command is the location you wish to search. Although you may specify a specific directory, you can use a metacharacter to serve as a substitute. The three metacharacters that work with this command include:
 +  * Period (.): Specifies the current and all nested folders.
 +  * Forward Slash (/): Specifies the entire filesystem.
 +  * Tilde (~): Specifies the active user's home directory.
 +
 +Find all files (not directories or links) of 1033 bytes in size that are not executable and which can be read (i.e., you can cat the file and read the contents):
 +
 +<code>find . -type f -size 1033c ! -executable -exec cat {} \;</code>
