[Chimera-users] count the selected residues in linux terminal

Respected sir/ma'am Greetings for the day! I want to use chimera commands in shell scripting or python. So, my problem is how to count the residues using Chimera? in gui we know that there is a magnifying icon at the lower right portion of the window, but while running in linux terminal I'm unable to generate the same results. Here is the attached ss of inspect selection, so if I want to print this in linux terminal what steps should I follow to get to this result? I'm trying my best to search in the tutorials but unable to create a command related to inspect selection. Kindly help me in this issue, it would be very grateful if you suggest the code. thank you, Regards Chittari Jaya Shree
