one , Experimental purpose ：
* master LINUX Issue file and directory operation commands ：cd,ls,mkdir,rmdir,rm.
* master LINUX Next file information display command ：cat,more.
* master LINUX Next file copy , Delete and move commands ：cp,mv.
* master LINUX File retrieval for , Sort command ：grep,sort.
two , Experiment content ：
1, Use the command to switch to /etc catalogue , And display the current working directory path .
2, Use command display /root Details of all file directories under the directory , Include hidden files .
3, Create a directory using the command /root/linux, Then delete the directory .
4, Using commands cat Using output redirection in /root Create file under directory abc, The contents of the document are “Hello,Linux!”, And view the contents of the file .
5, Use the command to create with the default permission of 744 Directory of /root/ak, Then /root/abc Copy files to this directory , Finally, delete the directory and the files under it .
6, see file /etc/passwd Before 3 Line content .
7, create a file file1, The contents of the document are 3 that 's ok , Respectively a,c,b, Sort the file data , Display on screen .
8, Use command display /etc/passwd File type of file .
9, In file /etc/passwd Search for matching characters in “root”.
three , Experimental environment ：
Windows 10
Workstation 16.x virtual machine
Red Hat Enterprise Linux 7 64 position

five , empirical conclusion
Through this experiment , I got it LINUX Issue file and directory operation commands ：cd,ls,mkdir,rmdir,rm. Got it LINUX Next file information display command ：cat,more
. Got it LINUX Next file copy , Delete and move commands ：cp,mv. Got it LINUX File retrieval for , Sort command ：grep,sort. Use while checking and recording , Deeper understanding .
