Working with Linux

This will execute the grep command on all the files returned by find. Let's also search inside the file
using vim, so that we verify the result is correct. As you can see, the text "manager" appears in this
file. You don't have to worry about {} \;, it's just standard -exec syntax.
Moving on with the practical examples, let's say you have a folder where you want to remove all the
files modified in the last 100 days. We can see our default_app folder contains such files. If we
combine find with rm like so:
find default_app -mtime -100 -exec rm -rf {} \;
We can do a quick cleanup. Find can be used for smart backups. For example, if we were to backup
all json files in the project we would combine find with the cpio backup utility using a pipe and a
standard output redirection:
find . -name "*.json" | cpio -o > backup.cpio
We can see that this command has created a backup.cpio file, of type cpio archive.
Now this could probably have been written with -exec also, but it's critical you understand that pipes
can also be used in this type of scenario, together with redirects.
When doing reports, you may have to count the number of lines written:
