Find has a useful option -exec which can be used to run a command on each file found. It has a couple of slightly obscure details to the syntax:

• {} is a placeholder for the filename.
• The command we are running with -exec needs to be terminated with a semicolon as there may be further arguments to find after it. This needs to be escaped as \; or ';', otherwise it will be interpreted as the end of the find command.

It is also possible to pass the -exec argument multiple times

Stringing this together allows us to assemble some elegant one-liners, for example:

# delete log files more than 60 days old
find ./logs -mtime +60 -name '*.log' -exec rm {} \;

# print the name and (array/object) length of all JSON files
find . -name '*.json' -exec printf {}\:\  \; -exec jq '. | length' {} \;

# recursively change permissions on files (ignore directories)
find . -type f -exec chmod 644 {} \;
