Telegram
Download Telegram for Linux. The downloaded file was tsetup.version.number.tar.xz
I am following the approach of installing additional software in the /opt folder. Untar it to /opt.
tar zxf tsetup.version.tar.xz -C /opt
The files are unzipped to /opt/Telegram and the file to execute is /opt/Telegram/Telegram
Typically, the permissions would be as below:
[mochapenguin@dv6tqe ~]$ ls -las /opt
