Question

Explain the ‘ls’ command in Linux?

Answer 1

ls is used to list information about files and directories within the file system.

Syntax to use ls:

ls [OPTIONS] [FILES]

Note:  When we used ls with no options and arguments then it displays a list of the names of all files in the current working directory.

There are different options that can be used with the ls command, here we have mentioned a few one of them.

• -l   lists long format (shows all permissions of the file).
• -ld  If you want the details of the directory.
• -i   lists files with their inode number.
• -s  lists files with their size.
• -a  lists all files including hidden files.
• -S  lists files with their size and sorts the list by file size.
• -t   sorts the listed files by time and date.
• -lh display file size in easy to read format.
