title	Other Windows ssh/Terminal options

If your Windows version does not have ssh in Command Prompt or PowerShell:

Download the free PuTTY suite of remote access tools, which includes a nice Terminal program: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html.
- Either the Putty installer or just putty.exe (Terminal) and pscp.exe (secure copy client)

More advanced options for those who want a full Linux environment on their Windows system:

Windows Subsystem for Linux – Windows 10 Professional includes a Ubuntu-like bash shells
- See https://docs.microsoft.com/en-us/windows/wsl/install-win10
- We recommend the Ubuntu Linux distribution, but any Linux distribution will have an SSH client
Cygwin (https://www.cygwin.com/)
- Includes an X-Windows server and an X11-enabled XTerm that can be installed

From now on, when we refer to "Terminal", it is either the Mac/Linux Terminal program, Windows Command Prompt or PowerShell, or the PuTTY program.

Now execute the lines below to set up a login script, called ~/.bashrc. [ Note the tilde ( ~ ) is shorthand for "my Home directory". See See Linux fundamentals: pathname Pathname syntax ]

When you login via an interactive shell, a well-known script is executed to establish your favorite environment settings. The well-known filename is ~/.bashrc (or ~/.profile on some systems), which is specific to the bash shell.

$WORK and $SCRATCH are TACC environment variables that refer to your Work and Scratch file system areas – more on these file system areas soon. (Read more about Environment variables)

Unlink

title	What is "ln -s" doing?

The ln -s command creates a symbolic link, a shortcut to the linked file or directory.

Here the link targets are your Work and Scratch file system areas
Having these link shortcuts will help when you want to copy files to your Work or Scratch, and when you navigate the TACC file system using a remote SFTP client
Always change directory (cd) to the directory where we want the links created before executing ln -s
- Here we want the links under your home directory (cd with no arguments)

Want to know where a link points to? Use ls with the -l (long listing) option.
