Hi folks,
I am very new to awk. I have what is probably a very simple question. I'm trying to get the max value of column 1, but also print column 2. My data looks like this:

uniq
uniq(1) User Commands uniq(1)NAME
uniq - report or filter out repeated lines in a file
SYNOPSIS
uniq [-c | -d | -u] [-f fields] [-s char] [ input_file [output_file]]
uniq [-c | -d | -u] [-n] [ + m] [ input_file [output_file]]
DESCRIPTION
The uniq utility will read an input file comparing adjacent lines, and write one copy of each input line on the output. The second and suc-
ceeding copies of repeated adjacent input lines will not be written.
Repeated lines in the input will not be detected if they are not adjacent.
OPTIONS
The following options are supported:
-c Precedes each output line with a count of the number of times the line occurred in the input.
-d Suppresses the writing of lines that are not repeated in the input.
-f fields Ignores the first fields fields on each input line when doing comparisons, where fields is a positive decimal integer. A
field is the maximal string matched by the basic regular expression:
[[:blank:]]*[^[:blank:]]*
If fields specifies more fields than appear on an input line, a null string will be used for comparison.
-s chars Ignores the first chars characters when doing comparisons, where chars is a positive decimal integer. If specified in con-
junction with the -f option, the first chars characters after the first fields fields will be ignored. If chars specifies
more characters than remain on an input line, a null string will be used for comparison.
-u Suppresses the writing of lines that are repeated in the input.
-n Equivalent to -f fields with fields set to n.
+m Equivalent to -s chars with chars set to m.
OPERANDS
The following operands are supported:
input_file A path name of the input file. If input_file is not specified, or if the input_file is -, the standard input will be used.
output_file A path name of the output file. If output_file is not specified, the standard output will be used. The results are unspeci-
fied if the file named by output_file is the file named by input_file.
EXAMPLES
