Butfirst, every Linux user has a home directory. You can use the tilde(~) to represent the home directory of any currently active user. Forexample, if your username is Vinita, your home directory is/home/Vinita. If you have logged in as the root user, your homedirectory is /root.

$cd [ destination directory path]It is easy to change directories in Linux. Just use cd and name theabsolute path of the desired directory. If you use the relative path,just remember that your final destination depends on the presentworking directory.

as you can see in the output of ls command file is in white color anddirectory is in blue color.

There are two path concepts associated with Linux directories:absolute paths and relative paths.An absolute path describes the complete directory structure basedon the top level directory, root (/).A relative path is based on the current directory. Relative paths donot include the slash in front.The difference between an absolute path and a relative one isimportant To know more about path and directory structure

the root (/) directory. The pwd command, which is short for printworking directory, can tell you, relative to root (/). Once you knowwhere you are, you can determine whether you need to move to adifferent directory.

$cd ..this command is used to exit from current directory.

cpThe cp (copy) command allows you to take the contents of one fileand place a copy with the same or different name in the directory ofyour choice. For example, the cp file1 file2 command takes thecontents of file1 and saves the contents in file2. One of the dangersof cp is that it can easily overwrite files in different directories,without prompting you to make sure that's what you really wanted todo.

mvYou can't rename a file in Linux, you can move it. The mv commandessentially puts a different label on a file. For example, the mv file1file2 command changes the name of file1 to file2. Unless you'removing the file to a different partition, everything about the file,including the inode number, remains the same.

rmrm command is used to remove the regular files. It will ask beforeremoving files.

rmdirit will remove the empty directory. If directory is full then use rm –rf
