Why was the dot (“.”) used as the destination parameter for mv?
Copying, Deleting, and Moving Files Step 1. Copying Files a. The cp command is used to copy files around the local file system. When using cp, a new copy of the file is created and placed in the specified location, leaving the original file intact. The first parameter is the source file and the second is the destination. Issue the command below to copy some_text_file.txt from the home directory to the cyops_folder2 folder:
[analyst@secOps ~]$ cp some_text_file.txt cyops_folder2/b. Use the ls command to verify that some_text_file.txt is now in cyops_folder2:
[analyst@secOps ~]$ ls cyops_folder2/ some_text_file.txtc. Use the ls command to verify that some_text_file.txt is also in the home directory:
[analyst@secOps ~]$ ls -l total 36 drwxr-xr-x 2 analyst analyst 4096 Aug 16 15:01 cyops_folder1 drwxr-xr-x 2 analyst analyst 4096 Aug 16 15:11 cyops_folder2 drwxr-xr-x 3 analyst analyst 4096 Aug 16 15:04 cyops_folder3 drwxr-xr-x 2 analyst analyst 4096 Sep 26 2014 Desktop drwx------ 3 analyst analyst 4096 Jul 14 11:28 Downloads drwxr-xr-x 8 analyst analyst 4096 Jul 25 16:27 lab.support.files drwxr-xr-x 2 analyst analyst 4096 Mar 3 15:56 second_drive -rw-r--r-- 1 analyst analyst 142 Aug 16 15:09 some_text_file.txt -rw-r--r-- 1 analyst analyst 254 Aug 16 13:38 space.txtStep 2. Deleting Files and Directories a. Use the rm command to remove files. Issue the command below to remove the file some_text_file.txt from the home directory. The ls command is then used to show that the file some_text_file.txt has been removed from the home directory:
[analyst@secOps ~]$ rm some_text_file.txt [analyst@secOps ~]$ ls -l total 32 drwxr-xr-x 2 analyst analyst 4096 Aug 16 15:01 cyops_folder1 drwxr-xr-x 2 analyst analyst 4096 Aug 16 15:11 cyops_folder2 drwxr-xr-x 3 analyst analyst 4096 Aug 16 15:04 cyops_folder3 drwxr-xr-x 2 analyst analyst 4096 Sep 26 2014 Desktop drwx------ 3 analyst analyst 4096 Jul 14 11:28 Downloads drwxr-xr-x 8 analyst analyst 4096 Jul 25 16:27 lab.support.files drwxr-xr-x 2 analyst analyst 4096 Mar 3 15:56 second_drive -rw-r--r-- 1 analyst analyst 254 Aug 16 13:38 space.txtb. In Linux, directories are seen as a type of file. As such, the rm command is also used to delete directories but the -r (recursive) option must be used. Notice that all files and other directories inside a given directory are also deleted when deleting a parent directory. Issue the command below to delete the cyops_folder1 folder and its contents:
[analyst@secOps ~]$ rm –r cyops_folder1 [analyst@secOps ~]$ ls -l total 28 drwxr-xr-x 2 analyst analyst 4096 Aug 16 15:11 cyops_folder2 drwxr-xr-x 3 analyst analyst 4096 Aug 16 15:04 cyops_folder3 drwxr-xr-x 2 analyst analyst 4096 Sep 26 2014 Desktop drwx------ 3 analyst analyst 4096 Jul 14 11:28 Downloads drwxr-xr-x 8 analyst analyst 4096 Jul 25 16:27 lab.support.files drwxr-xr-x 2 analyst analyst 4096 Mar 3 15:56 second_drive -rw-r--r-- 1 analyst analyst 254 Aug 16 13:38 space.txtStep 3. Moving Files and Directories a. Moving files works similarly to copying files. The difference is that moving a file removes it from its original location. Use the mv commands to move files around the local filesystem. Like the cp commands, the mv command also requires source and destination parameters. Issue the command below to move the some_text_file.txt from /home/analyst/cyops_folder2 back to the home directory:
[analyst@secOps ~]$ mv cyops_folder2/some_text_file.txt . [analyst@secOps ~]$ ls –l cyops_folder2/ total 0 [analyst@secOps ~]$ ls –l /home/analyst/ total 32 drwxr-xr-x 2 analyst analyst 4096 Aug 16 15:13 cyops_folder2 drwxr-xr-x 3 analyst analyst 4096 Aug 16 15:04 cyops_folder3 drwxr-xr-x 2 analyst analyst 4096 Sep 26 2014 Desktop drwx------ 3 analyst analyst 4096 Jul 14 11:28 Downloads drwxr-xr-x 8 analyst analyst 4096 Jul 25 16:27 lab.support.files drwxr-xr-x 2 analyst analyst 4096 Mar 3 15:56 second_drive -rw-r--r-- 1 analyst analyst 142 Aug 16 15:11 some_text_file.txt -rw-r--r-- 1 analyst analyst 254 Aug 16 13:38 space.txt
