Today, I tried to explore and customize Ubuntu.
Track CPU and Memory Usage in Ubuntu Using Indicator-Sysmonitor
It’s clearly explained in the following link.
Then to note time of consumption by a particular command. You can use command
$time <your command>
Example:- $ time renderd -f -c /usr/local/etc/renderd.conf
For the first time I used bitbucket. It’s versioning control system.
For it install mercurial.
$ sudo apt install mercurial
$ hg clone https://bitbucket.org/lawgon/osmindia
