I am generating 50 random strings, each 11-character long by running:
cat /dev/urandom | LC_ALL=C tr -dc 'A-Z' | fold -w 11 | head -n 50
Now, how could I constrain the first character to always be letter R?

Hi there, I am new to linux. I am trying to install a software. Readme file says to:
"Make a copy of the file to a location in your manual system"
What does it mean by "manual system"?
Thank you for any help
