[ale] Your Go-To CLI Tools?

[Lightner, Jeff]

Some of my favorites have been listed (e.g. dmidecode and others).    A couple that haven't:

lsof  = List open files - Great for seeing how many file descriptors are in use and what they are (e.g. sockets, regular files, etc...).   But I use it primarily for looking at networking stuff.   The "-i" flag will let you find things using a given port or a given address (or both).   It also has a "-p" that lets you see things for a specific process and a "-a" for "and" that lets you get specific as you want (e.g. lsof -p 394 -a -i would show only the networking associated with PID 394.)   It has dozens of options and I almost never use netstat because of its capabilities.)

atop  = Like htop is an improved performance monitor but it will also store history like sar and you can get history down to process level (similar to old HP-UX Glance's abilities in the past).

multipath = Not really a utility (a daemon) but the multipath.conf is highly configurable so that one can assign specific names to multipath devices that are better than the "/dev/mpath/mapth##")

I think that is the same, just for ansible.
