awk -sed help : forth . to convert to "space"
Hi Experts,
Good day,

I am looking for the 6th fields 4th dot (.) to convert into a space in the output.

file:

Code:
tcp        0      0  10.80.110.100 2900     1 10.40.104.6.42769     ESTABLISHED
tcp        0      0  10.80.110.100 2900     1 10.40.103.7.38620     ESTABLISHED
tcp        0      0  10.80.110.100 2900     1 10.40.101.8.11764     ESTABLISHED
tcp        0      0  10.80.110.100 2900     1 10.40.102.9.49338     ESTABLISHED


- Desired output to be:
Code:
tcp        0      0  10.80.110.100 2900     1 10.40.104.6 42769     ESTABLISHED
tcp        0      0  10.80.110.100 2900     1 10.40.103.7 38620     ESTABLISHED
tcp        0      0  10.80.110.100 2900     1 10.40.101.8 11764     ESTABLISHED
tcp        0      0  10.80.110.100 2900     1 10.40.102.9 49338     ESTABLISHED


Thank a lot...

If it's a small file, then a very simple ksh version may be sufficient:-
Code:
while read type count1 count2 local port other remote state
do
  echo "$type $count1 $count2 $local $port $other ${remote%.*} ${remote##*.} $other"
done < inputfile > outputfile

You can format the column width with typeset commands if you wish.

The variable substitution with $remote is as follows:-
${remote%.*} says to remove everything from end of $remote at the shortest length that matches a dot, i.e. you get the first four parts.
${remote##*.} says to remove everything from start of $remote at the longest length that matches a dot, i.e. you are left with the last part.
I hope that this helps.

you may try

Code:
$ cat test

Code:
awk  -F"." '{for(i=1;i<=NF;i++)printf (i==7)? $i OFS : (i<NF)?$i FS:$i;printf RS}' test

resulting

FS="." ---> Field separator is dot (.)
for(i=1;i<=NF;i++) ---> start loop from 1st Field to 8th Field
(i==7)? ---> If field is 7th one then print $7 and Output separator (OFS) by default output separator is set to space, else check field is less than 8 (i<NF)?, if yes print column and field separator that is dot(.). if field is greater than 7 then just print column, once loop completes print newline that is RS (Row separator)

Hello Akshay,

When code will get the value for 7th column, then I have query if we are setting the OFS to default which is space then how it is putting space at the last
Code:
.(dot)

not between every
Code:
.(dot)



I mean it should be like as

Code:
10 40 104 6 4276


could please explain?


Thanks,
R. Singh

Another way with sed :
Code:
sed 's/\.\([^.]*\)$/ \1/' file

or
Code:
sed 's/\./ /7' file
