Deployment

  1. Login to the server as super user (root) and perform below
  2. Create the file and directory structure shown in the above diagram.
  3. Perform below steps
    1. Create directory – /dir6/dir4

    7. Rename the file ‘/f2′ to /f4’
    8. Create directory – “/home/user2/dir1”
    9. keeping  “/dir2/dir1/dir2/dir10” as present working directory; create file “/opt/dir14/dir10/f1” using relative path method.
    10. Move the file from “/opt/dir14/dir10/f1” to  user2/dir1 directory
    11. Delete the directory recursively “/dir4”

  7. LOGIN TO THE SERVER AS SUPER USER (ROOT) AND PERFORM BELOW
    ANS :-> sudo su –
    CREATE THE FILE AND DIRECTORY STRUCTURE SHOWN IN THE ABOVE DIAGRAM.

    cd /
    mkdir -p dir1 dir2/dir1/dir2 dir3/dir1 dir4/dir12 dir5/dir13 dir6 dir7/dir10 dir8/dir9 opt/dir14/dir10

    PERFORM BELOW STEPS
    CREATE DIRECTORY – /DIR6/DIR4
    mkdir -p /dir6/dir4

    CREATE FILE – /F3
    touch /f3

    MOVE THE FILE FROM “/DIR1/F1” TO “/DIR2/DIR1/DIR2”
    touch /dir1/f1 ; mv /dir1/f1 /dir2/dir1/dir2

    RENAME THE FILE ‘/F2′ TO /F4’
    touch /f2 ;mv /f2 /f4

    CREATE DIRECTORY – “/HOME/USER2/DIR1”
    mkdir -p /home/user2/dir1

    KEEPING “/DIR2/DIR1/DIR2/DIR10” AS PRESENT WORKING DIRECTORY; CREATE FILE “/OPT/DIR14/DIR10/F1” USING RELATIVE PATH METHOD.
    cd /dir2/dir1/dir10;mkdir -p /opt/dir14/dir10; touch /opt/dir14/dir10/f1

    MOVE THE FILE FROM “/OPT/DIR14/DIR10/F1” TO USER2/DIR1 DIRECTORY
    cd /home ; mv /opt/dir14/dir10/f1 user2/dir1

    DELETE THE DIRECTORY RECURSIVELY “/DIR4”
    rm -r /dir4 (if it is empty directory we can use rmdir /dir4)

    DELETE ALL CHILD FILES AND DIRECTORIES UNDER “/OPT/DIR14” USING SINGLE COMMAND.
    rm -r /opt/dir14

    CREATE FILE “/DIR1/F2”
    touch /dir1/f2

    DELETE /DIR6
    rm -r /dir6

    DELETE /DIR8
    rm -r /dir8

    DELETE /F3
    rm /f3

    SEARCH FOR THE FILE NAME ‘F4’ IN THE SERVER AND LIST ALL OBSOLETE PATHS WHERE F4 FILE IS FOUND.
    ls -lR / | grep ‘f4’
    make sure we are doing it from root directory .

    SHOW THE COUNT OF THE NUMBER OF FILES IN THE DIRECTORY ‘/’
    ls -1 | wc -l

    DELETE /DIR1
    DELETE /DIR2
    DELETE /DIR3
    DELETE /DIR5
    DELETE /DIR7

    rm -r /dir1 /dir2 /dir3 /dir5 /dir7

    DELETE /F1 & /F4

    rm /f1 /f4
    DELETE /OPT/DIR14

    rm -r /opt/dir14

  10. I have completed the task, I have a doubt regarding searching for a file I used the command find /f4 to find f4 under the / directory
    in the result i could see all the files and its absolute path is there a command which just gives us the result which contains only the details of file f4

  11. 1. Create the file and directory structure shown in the above diagram.
    [root@ip-172-31-80-55 ~]# mkdir /dir1
    [root@ip-172-31-80-55 ~]# touch /dir1/f1
    [root@ip-172-31-80-55 ~]# mkdir -p /dir2/dir1/dir2/dir10
    [root@ip-172-31-80-55 ~]# touch /dir2/dir1/dir2/f3
    [root@ip-172-31-80-55 ~]# mkdir -p /dir3/dir11
    [root@ip-172-31-80-55 ~]# mkdir -p /dir4/dir12
    [root@ip-172-31-80-55 ~]# touch /dir4/dir12/f5
    [root@ip-172-31-80-55 ~]# touch /dir4/dir12/f4
    [root@ip-172-31-80-55 ~]# mkdir -p /dir5/dir13
    [root@ip-172-31-80-55 ~]# mkdir dir6
    [root@ip-172-31-80-55 ~]# mkdir -p /dir7/dir10
    [root@ip-172-31-80-55 ~]# touch /dir7/f3

    [root@ip-172-31-80-55 ~]# touch /f2
    [root@ip-172-31-80-55 ~]# touch /f1
    [root@ip-172-31-80-55 ~]# mkdir -p /opt/dir14/dir10
    [root@ip-172-31-80-55 ~]# touch /opt/dir14/f3

    Perform below steps
    2. Create directory – /dir6/dir4
    [root@ip-172-31-80-55 ~]# mkdir -p /dir6/dir4

    3 Create file – /f3
    [root@ip-172-31-80-55 ~]# touch /f3

    4 Move the file from “/dir1/f1” to “/dir2/dir1/dir2”
    [root@ip-172-31-80-55 dir1]# mv * /dir2/dir1/dir2

    5 Rename the file ‘/f2′ to /f4’
    [root@ip-172-31-80-55 dir1]# mv /f2 /f4

    6 Create directory – “/home/user2/dir1”
    [root@ip-172-31-80-55 dir1]# mkdir -p /home/user2/dir1

    7 keeping “/dir2/dir1/dir2/dir10” as present working directory; create file “/opt/dir14/dir10/f1” using relative path method.
    [root@ip-172-31-80-55 dir10]# touch ../../../../opt/dir14/dir10/f1

    8 Move the file from “/opt/dir14/dir10/f1” to user2/dir1 directory
    [root@ip-172-31-80-55 dir10]# mv f1 /home/user2/dir1
    9 Delete the directory recursively “/dir4”
    [root@ip-172-31-80-55 dir10]# rm -r /dir4
    rm: descend into directory ‘/dir4’? y
    rm: descend into directory ‘/dir4/dir12’? y
    rm: remove regular empty file ‘/dir4/dir12/f5’? y
    rm: remove regular empty file ‘/dir4/dir12/f4’? y
    rm: remove directory ‘/dir4/dir12’? y
    rm: remove directory ‘/dir4’? y

    10 Delete all child files and directories under “/opt/dir14” using single command.
    [root@ip-172-31-80-55 dir10]# rm -rf /opt/dir14/dir10

    [root@ip-172-31-80-55 dir10]# rm -r /dir8
    14 Delete /f3
    [root@ip-172-31-80-55 dir10]# rm -r /f3
    15 Search for the file name ‘f4’ in the server and list all obsolete paths where f4 file is found.
    [root@ip-172-31-80-55 dir10]# find / -name f4
    [root@ip-172-31-80-55 dir10]# find / -name f3
    /dir2/dir1/dir2/f3
    /dir7/f3

    16 Show the count of the number of files in the directory ‘/’
