At the end of the semester, the Linux practice class teacher is very kind, decorate is a big job to get started: Implement a simple version of the LS command. Three files, upload first.Ls2.c#include Ls_header.h#include Ls_util.h#include Simple implementation of the LS command under Linux

LS lists the file names.-l lists the long file names.-rwxr-xr--1 root root 10739 Dec 13:31 Bbscon(7) (4) (5) (6) (3) (2) (1)From left to right, it is divided into 7 columns with the following meanings:(1) The file name, if it is a symbolic link, also displays the linked object after the file name.(2) The time of the last modification of the document, if the changes made in the last one months, the month, day, hour, and minute are displayed, otherwise,

Using LINUX-C programming to implement simple LS commandsThe specific code is as follows:The loaded header file has stdio.h,sys/types.h,dirent.h,unistd.h,sys/stat.h,fcntl.h,string.h and so on.Voidmain (INTNBSP;ARGC,CHARNBSP;**ARGV) {dir*dir; structdirent*rdir;structstatstatbuf; char*buffer= "/"; char*file_;char *p;intlenght=strlen (Argv[argc-1]);int len=argc;charparameter[]={' i ', ' t ', ' a ', ' u ', ' G ', ' B ', ' s '};//parameter group if (argc=

Simple LS implementation, first, we need to traverse the parameters directory under the various files, and then according to the nature of the file, read the permissions of the file, user group, user name, size, the last time to access, and then according to the name of the order displayed.The specific function declarations are as follows:1#include 2#include 3#include string.h>4#include 5#include 6#include 7#include 8#include 9#include Ten#include On
