Basic commands of LINUX
Here you can see the basic commands of Linux that you can use in the GUI terminal.
Firstly ” cd ” command
It means change directory, it will change the directory when you are in the current directory.
when you give the only ” cd ” command in the terminal it will directly take you to the HOME.
If you want to go to some selected directory int the current directory by this command it will take you to that directory
eg: ” cd Documents/ ”
In the LINUX terminal we have the one flexibility that we can use the TAB key that will help us to automatically it will fill the command and if you press double the key then it will list the files that to fill in the terminal.
” cd .. ”
By this command, it will take you back from your the current directory
” cd ~ ” or only ” cd ”
It also takes you to the HOME directory, where ever you are in the current directory.
” pushd ”
From this command, you can go to the selected directory from wherever you are in the current directory.
eg: ” pushd etc/ ”
It will take you to the etc directory.
” popd ”
After you using the pushd command that will take you to selected directory that what you gave in the terminal and the by this command you can come back to the original directory that where you are before pushd command.
” locate ”
it is how to find the file in the system, there is so many bunches of files in the system. If you want to locate a selected file this command will helpful to locate the file.
eg: ” locate Filename ”
this will give the path of the file.
” su ”
It is the command to switch to the root, this will ask password to access in the root.
