Try it again, but type the command carefully. Also, check that your example data file has no typos. The example file I created from your first post returned machine1 and 3 as expected.

Specifically adding a space at the beginning of a search string (for whatever reason you might have...) is easily accomplished:

awk '/machine/{store=$0} / qwerty/ {print store}' "file"

Note the difference from the original:
awk '/machine/{store=$0} /qwerty/ {print store}' "file"

But the original will still return the correct results since "qwerty" (based on the data you provided) is in the string regardless of there being anything before or after the word.

In your second example, the common element in your stanza names would seem to be that they end with a colon.
awk '/:/{store=$0} / velocity/ {print store}' "file"
Hi Ghostdog74 and Flying_Meat,
Thanks to both of u ....the code works as expected..

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
