How Do I Grep the Latest File in Unix?

How do I grep the latest file?

How it works:

1. find /var/log/folder -type f -printf ‘%[email protected] %p ’ This looks for files and prints their modification time (seconds) followed by a space and their name followed by a nul character.
2. sort -rz. This sorts the null-separated data.
3. sed -Ezn ‘1s/[^ ]* //p’ …
4. xargs –null grep string.
