This is where I document my studies, learnings on Linux
$ cd /home/raybaba/ Press TAB twice and it will show all dirs in $ cd /home/raybaba/
ls: list all dirs $ cd Desktop/ This goes to the Desktop dir
cd /: This takes one to the root dir Windows machine use backlash eg cd \ProgramFiles
cd .. : This takes one back to the last dir
[raybaba@localhost /]$ cd ~ : This takes one back to the root dir
[raybaba@localhost /]$ cd ~/Desktop : This takes one straight to any directory you want
[raybaba@localhost /]$ ls -l Shows more details, rights etc of each directory. It is more verbose than mere typing [raybaba@localhost /]$ ls
[raybaba@localhost var]$ ls -lha [raybaba@localhost var]$ ls -la [raybaba@localhost var]$ ls -lah
Boths commands show more info as well as file sizes in human readable format
[raybaba@localhost var]$ ls --help This is a way to get more information on a command
