-r is the option
to check whether file/directory has read permission or not!!!

This is the code to check whether the file is readale or not but is there any command that show me the list of all readable files.for eg:-

ls -a shows all the hidden files & directories

.. or for those of us who do not like to type that much

ls -l

and quickly scan the permissions column
There isn't a command that shows you which files are readable because all files are created readable. You'd have to manually make a file unreadable, so it makes no sense to have a command that displays only readable files, since 99.99% of files are readable.

you can use that to acheive ur objective of determining list of all readable files/directories.
