echo Hi
will print to screen
ls
will list files and folders in current location
cd
will change the directory by using cd followed by the file or folder
pwd
will print the currently directory you are in
mkdir
will make a new folder / directory
cd new_directory; mkdir new_folder; pwd
you can run multiple commands by using the semicolon followed by the next command in order. In this example it will enter into the new_directory, create a new folder and then present the current workign directory
mkdir -p /tmp/asia/india/bangalore
by using the -p command we can create a directory tree in one command input instead of creating each directory or folder individually
rm -r /tmp/my_dir1
this will remove the directory called my_dir1
cp -r my_dir1 /tmp/my_dir1
will copy the directory called my_dir1
touch new_file.txt
will create a new text file called new_file in the current directory
cat > new_file.txt add text to the file then control + d to exit
cat new_file.txt to view the contents of the file
cp new_file.txt copy_file.txt this will copy the file
mv new_file.txt sample_file.txt this will move file, if its in the same location it will work as if its renamed
rm new_file.txt to remove a file
