20. Combining other commands with the find command
. You can also use the find command to find a file and then carry out a command on that file. To do this use the command: find pathname -name filename -print -exec command {}\; . To be prompted for confirmation before the command is executed use the command: find pathname -name filename -print -ok command {}\; . The command must be followed by a \ (backslash) and a ; (semi-colon). The {} (pair of braces) substitute the pathname of the file that is found as an argument to the command. Examples .
