Write an awk script named extract. awk to extract a portion of the input file(s) as follows. somewhere after a line containing exactly the text "start from here", find the first line containing exactly the text "nextline" and display the following line. no other lines should be displayed. if the specific lines are not present, then the script should display nothing. for example: [user]$ cat test0.txt
start from here
nextline
this is the one we want
not this one.
nor this one.
[user]$ extract. awk test0.txt
this is the one we want
[user]$ cat test1.txt
ignore everything up here
nextline
ignore these lines also because we
did not see the first magic line yet.
start from here
more lines to ignore
nextline
this should be displayed
this should not
nextline
this is too late so do not display it
start from here
only the first occurrence matters so
nextline
none of this will be displayed either
[user]$ extract. awk test1.txt
this should be displayed
[user]$ cat test2.txt
1
this file has no magic text
anywhere!
[user]$ extract. awk test2.txt
[user]$
