A common combination to use is the -a parameter to list all files, the -i parameter to list the inode for each file, the -l parameter to produce a long listing, and the -s parameter to list the block size of the files. The inode of a file or directory is a unique identification number the kernel assigns to each object in the filesystem. Combining all of these parameters creates the easy-to-remember -sail parameter.
