Linux / Unix: scp Copy All Hidden Dot Files

last updated in Categories ,

I‘m using scp command to copy files from one server to another server. The problem is that I’m unable to copy all hidden files (such as .bash_history). How do I copy hidden files using the scp command under Unix like operating systems?

Linux Disable /var Access Time Updates ( noatime )

last updated in Categories , , , , ,

I‘ve configured and mounted /var for squid caching and other purposes under Linux. I’ve noticed that the Linux file system keeps records of when files are created, updated, and accessed. My /var is exclusively used for caching purpose and I do not want to waste disk I/O while updating last-time-read attribute during reads and writes to files. How do I disable access time updates for /var partition?
