Shell Commands and Utilities

This is a terse collection of commands and utilities I find useful for shells. There is little distinction between programs and commands as commands are programs (and are installed or come pre-installed) and programs have commands. Also included is a shell (Fish Shell) and some other shell applications/utilities (Mosh, Nano). Shell Commands cat - display […]

Fish Shell – Friendly Interactive SHell

Fish Shell is a very useful shell. I use it on OSX and Linux. Provides for some sanity at the command line. For an editor I use Nano. Note that there are some limitations, and a learning curve on getting it set up. However, it does have some limitations, and is definitely newer than other […]

Nano Command Line Text Editor

Nano is pretty awesome, fully open source, and has mnemonics for most commands. Note that I use Fish Shell on OSX, CentOS and Ubuntu. Various benefits accrue, when scripting and also autocomplete and such. Various Commands and Such Set Nano as default editor of git in OSX Search and Replace Apparently this is also case […]

ntpd, ntpdate, chrony on CentOS

First we need to back up to a set of core principles in order to then find the configuration that will work for production servers. Production Server Principles […]

SCP – Secure Copy

scp, the secure version of cp, aka copy, is pretty great, since it is straightforward to copy one or more files or directories from any one machine to any other machine (and the command could be running on a third machine). SCP Syntax scp (-r = recursive) (-i private key) (user@server:directory/file) or (/local/directory/file) (-i private […]

Mobile and Desktop Intel Linux

05-Nov-2016 - Note: I've reached the conclusion that I will entertain no more underpowered devices as they are ultimately so limited their return on investment vastly underperforms overpowered devices. This means chromebooks are no longer acceptabe acceptable. Things will change, but at this point (late October, 2016), it appears that the Skylake processors are horrible […]

Future of the Desktop

05-Nov-2016 - Note: I've reached the conclusion that I will entertain no more underpowered devices as they are ultimately so limited their return on investment vastly underperforms overpowered devices. This means Intel Compute Sticks are no longer acceptabe acceptable. The Intel NUC is now what I consider to be the future of the desktop. I've […]
