Code to get the IP address and format it to run in nmap

For scanning my subnet using my IP address, I need to run the following command



nmap -sn 192.168.100.*


I want to extend this functionality such that I don't have to manually specify the first three parts of the IP range myself. I came up with this rough solution.



ip=$( hostname -I | awk '{print $1}' | awk -F. '{print $1; print $2; print $3}' ORS="."; echo -n "*"); 

nmap -sn $ip


Is there a more cleaner way of achieving the same?

          Create new schema in PostgreSQL using DBeaver

          Image
          0 At the beginning of my current job I had limited access to DB but recently my role is changed to superuser, admin, and owner. My colleague who was the previous DB admin is able to create a schema or change the permissions as there is a permission tab in the properties and he can change permissions by clicking easily. Would you please let me know how I can create schema and change permissions as well? Why his dbeaver looks different from me? He can easily right click on the schema folder on top of all schemas on the left side column and select create new schema while I do not have that, like the following picture I found on the internet. postgresql database-schema dbeaver share | improve this question

          Deepest pit of an array with Javascript: test on Codility

          Image
          0 $begingroup$ This is the question from a Codility test, as a task in an interview: DeepestPit - problem description A non-empty zero-indexed array A consisting of N integers is given. A pit in this array is any triplet of integers (P, Q, R) such that: ·         0 ≤ P < Q < R < N; ·         sequence [A[P], A[P+1], ..., A[Q]] is strictly decreasing, i.e. A[P] > A[P+1] > ... > A[Q]; ·         sequence A[Q], A[Q+1], ..., A[R] is strictly increasing, i.e. A[Q] < A[Q+1] < ... < A[R]. The depth of a pit (P, Q, R) is the number min {A[P] − A[Q], A[R] − A[Q]}. For example, consider array A consisting of 10 elements such that: A[0] = 0 A[1] = 1 A[2] = 3 A[3] = -2 A[4] = 0 A[5] = 1 A[6] = 0 A[7] = -3 A[8] = 2 A[9] = 3 Triplet (2, 3, 4) is
