Issue
I have a file file
with content like:
stringa 8.0.1.2 stringx
stringb 12.01.0.0 stringx
I have to get a substring from field 2 (first two values with the dot).
I am currently doing cat file | awk '{print $2}' | awk -F. '{print $1"."$2}'
and getting the expected output:
8.0
12.01
The query is how to do this with single awk?
I have tried with match() but not seeing an option for a back reference.
Any help would be appreciated.
Solution
You can do something like this.
$ awk '{ split($2,str,"."); print str[1]"."str[2] }' file
8.0
12.01
Also, keep in mind that your cat
is not needed. Simply give the file directly to awk
.
