Using wildcard in awk programming, how ?

sarajevo · 10-18-2006, 06:14 AM

Hi people,
I have statement
awk ' { if(( $9=90*) && ($9=91*) && ($9=92*)) print $9 }'> /home/some_file.txt
where with * I want to select all numbers which begin with 90, 91, 92, and no mater which number is later. There is 4 numbers after 90, 91, 92.

how use wild wildcards in this case to print out all that numbers.

Thanks

Hi,

Is this what you want:

awk '$9 ~ /^9[0-2]/ { print $9 }' infile > outfile

This checks to see if field 9 starts (^) with a 9, followed by 0,1 or 2 ([0-2]). If this is the case field 9 is printed, no matter what else is after ^9[0-2].

Hope this helps.
