file size kuda ante use ls -ltr...this command lists all the files and its sizes in a directory

cat filename ani evvali...for example cat file.txt ante aa file lo unna content chupistadi....more file.txt kuda use cheyyochu to see the contents of a file

vi file.txt ani evvu...dont forget the file extension.....
