Selecting specific 'id's from lines and columns using 'SED' or 'AWK'
Hello experts,
I am new to this group and to 'SED' and 'AWK'. I have data (text file) with 5 columns (C_1-5) and 100s of lines (only 10 lines are shown below as an example). I have to find or select only the id numbers (C-1) of specific lines with '90' in the same line (of C_3) AND with '20' in their previous line (of C_3) AND '40' in their next line (of C_3). That is, the id-list should represent all three conditions altogether.

My Data File:

C_1 C_2 C_3 C_4 C_5
1 1 90 0 406
2 0 20 -1 1500
3 1 90 0 377
4 0 60 -1 1500
5 4 90 1 275
6 0 40 -1 1500
7 4 90 1 228
8 0 80 -1 1500
9 1 90 0 414
10 0 60 -1 1500
-- - -- -- ---

Any 'SED' or ''AWK' command(s) could do this task..?
I would greatly appreciate your help..!

Thanking you in advance...!
Kamu

fmt

fmt(1)							      General Commands Manual							    fmt(1)

NAME

       fmt - format text

SYNOPSIS

       width] [file...]

DESCRIPTION

       The  command is a simple text formatter that fills and joins lines to produce output lines of (up to) the number of characters specified in
       the width option.  The default width is 72.  concatenates the arguments.  If none are given, formats text from the standard input.

       Blank lines are preserved in the output, as is the spacing between words.  does not fill lines beginning with a	period	for  compatibility
       with Nor does it fill lines starting with

       Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used).

       can also be used as an in-line text filter for the command:

       reformats the text between the cursor location and the end of the paragraph.

   Options
       recognizes the following options:

	      Crown margin mode.
		    Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that
		    of the second line.  This is useful for tagged paragraphs.

	      Split lines only.
		    Do not join short lines to form longer ones.  This prevents sample lines of code, and other such "formatted" text, from  being
		    unduly combined.

	      Fill output lines to up to
		    width columns.

WARNINGS

       The width option is acceptable for BSD compatibility, but it may go away in future releases.
