Help with cleansing data
I have a file with 27 fields seperated by pipe. I have a field 17 that is defined as numeric and the data coming in might contain character and
other miscellaneous data like (@,!,~,#,%,^,&,*,(,)).

I have to make sure that the column strictly contains numeric data and if it contains any of the characters or the special characters mentioned
above, they should be made to be null. can somebody let me know how I can do that.

sample data row

Something like that :
Code:
awk BEGIN { FS=OFS="|" } { if ($17 !~ /^[[:digit:]]*$/) $17=""; print $0 }' inputfile
