Top Forums UNIX for Advanced & Expert Users Search for columns with numbers greater than 70 Post 303037439 by MadeInGermany on Thursday 1st of August 2019 11:59:10 AM

The trailing % sign makes $5 a string, and the > compares strings.
The +0 ensures that the > compares numbers.
Most awk versions will then ignore the trailing % sign.
But a few awk versions convert such strings to zero; they need
Code:
awk 'sub(/%$/,"",$5) && $5 > 70'

The sub() should return 1 (true) on a successfull substitution. So maybe you can omit a further test like $2~/dev/.

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
