linux - AWK remove blank lines
Answer
Answer
The /./ is removing blank lines for the first condition { print "a"$0 } only, how would I ensure the script removes blank lines for every condition ?
awk -F, '/./ { print "a"$0 } NR!=1 { print "b"$0 } { print "c"$0 } END { print "d"$0 }' MyFile
Answer
Put following conditions inside the first one, and check them with if statements, like this:
awk -F, '
/./ {
print "a"$0;
if (NR!=1) { print "b"$0 }
print "c"$0
}
END { print "d"$0 }
' MyFile
