du and ls show different sizes for the same file
After uncompressing a file i was confused to see different sizes for the same file with du and ls command
When i used du it was showing the size
But ls output was showing a different size
So i realized these commands works in different ways
ls with option -l shows the allocated size but du shows the actual size (amount of space used).
If you want to see actual size with ls use -s option. If you use this way you can see both ls and du gives same output, in this case actual size is printer first
