　　The LS command is the most commonly used command under Linux. ls command is the abbreviation of the list, the lack of saving LS is used to print out the current directory of the list, if LS specifies a different directory, then display the list of files and folders in the specified directory.

The LS command can be said to be the most commonly used command under Linux.-A lists all files under the directory, including the.

The LS command is one of the most commonly used commands under Linux to query the contents of a directory (list directory contents). This article will describe its basic usage and some typical use cases. I use the test environment for Ubuntu 16.04.Basic OutputEnter LS directly in the command line and enter. This is the most streamlined usage, because we omit all options and parameters, and the output is the

Test instructionsThere are n filenames, sorted by column precedence, left-aligned output. The longest file name is the length of M, the last column is M, and the other column length is m+2.Analysis:The problem is very simple, but to write the code to refine, still need to think about it.
