what is difference between l and ls commands `ls` command shows the following : `a code controller.js mani sparat this ubuntu.gif ` `l` command the shows similar to that : `a/ code/ controller.js mani/ sparat/ this/ ubuntu.gif ` What is difference between them ?

`l` is probably a shell alias. On my Ubuntu 14.04 by default it is :


alias l='ls -CF'


From the `man ls page`, these flags mean :


-C list entries by columns
-F, --classify
append indicator (one of */=>@|) to entries


Type `alias l` to find out what actually the `l` command is calling.
