Installing Xilinx Vivado on RHEL through putty

I was installing Vivado 2015.4 on RHEL. I am working through a putty session and was facing the following error

Xilinx_Java_xauth

Surprisingly through the same putty session I was able to launch gedit or any other graphical program.

Googled around and came across this article.

It fit my situation to the T and the answer was appropriate as well.

Problem solved. Moving on to save the world!!!

 

Installing Xilinx Vivado on RHEL through putty

Move to first character on the command line

I am using CSH inside SCREEN on a PUTTY terminal. When I have to repeatedly enter similar commands, I tend to press the up arrow or use the shell history to bring up the command at the prompt. However I realise that there is a switch right at the beginning of the command that I need to change.

How do I quickly move to the first character of the command

Nope!!! <HOME> does not work for me.

Instead I press Ctrl + x twice to toggle cursor position from the first character to the last character of the command.

I do not know if this shortcut is provide by CSH or by Screen or by Putty, but it does work for me right now.
