Secure Shell on macOS, Unix, and Linux Installation Any modern Unix-like operating systems should come with secure shell client utilities already installed. This is true for macOS, Ubuntu, Fedora, Mandrake Linux, FreeBSD and many others. If, however, you need a ssh client, you can download one from the openssh website:

Emacs Tips Emacs Command Shorthand From the emacs built in tutorial Emacs commands generally involve the CONTROL key (sometimes labeled CTRL or CTL) or the META key (sometimes labeled EDIT or ALT).

SSH Keys on Microsoft Windows using the PuTTY Utility SSH keys are what you will use to establish an encrypted connection over the network, e.g. the internet, between your system and a remote machine. The default type of key to generate is RSA which is good for most purposes. RSA is universally supported among SSH clients. Note that EdDSA performs much faster and provides the same level of security with significantly smaller keys. In general, though, for what you need to do, RSA encryption is …

Keyring Issues If you are using an application, e.g. GitHub, and you get an error because of your “keyring” then a quick workaround is to find that keyring and push it out of the way.

System Priorities Priorities of programs are something to be aware of. PS The first thing to do is to get to know your processes. The ps command lists out the processes you have running on the system. By using ps -l, an extended listing of your processes is provided. The fields of the most interest to this topic are the PID, NI, and COMMAND fields. The COMMAND field lists the name of the command that started your process. So, if you're looking for your runaway c++ program, a.out is the one yo…
