Adding Fields to the file

Hi All,

I get a file on weekly basis from client. I need to write a script which make sure the file should have 20 columns after the first column. If not then the script should add the remaining columns and default them to space(except for 2nd and 3rd). and at the same time the script should check the second and the third column if null then default those to ND.

Sample Input file:
Code:
0000000000||3|MAIL ORDER|MAIL ORDER DATA|N/A|MAIL ORDER|N/A|
0000010001|CASH||CASH|CASH|N/A|CASH|N/A|
0000020002|FFS MED|2|AL MEDICAID|MEDICAID|N/A|AL MEDICAID|N/A|"Tier2,PA|NPF"

Sample Outfile Required:
Code:
0000000000|ND|3|MAIL ORDER|MAIL ORDER DATA|N/A|MAIL ORDER|N/A| | | | | | | | | | | |
0000010001|CASH|ND|CASH|CASH|N/A|CASH|N/A| | | | | | | | | | | |
0000020002|FFS MED|2|AL MEDICAID|MEDICAID|N/A|AL MEDICAID|N/A|"Tier2,PA|NPF"| | | | | | | | | | |

Any help appreciated. Thanks in advance Smilie

Hi Arun,

Please code tags. don't use icode tags. icode tags are used for displaying in the line itself like this...

Try

Code:
awk -F\| '{for(i=(NF+1);i<=20;i++){$i=" "};$2=$2?$2:"ND";$3=$3?$3:"ND";}1' OFS="|" file

There's a couple of other ways you can do this in awk. The shorter one I forget, but there's this:

Code:
$ awk 'BEGIN {FS=OFS="|"} NF<19{$19=FS}1' file
0000000000||3|MAIL ORDER|MAIL ORDER DATA|N/A|MAIL ORDER|N/A||||||||||||
0000010001|CASH||CASH|CASH|N/A|CASH|N/A||||||||||||
0000020002|FFS MED|2|AL MEDICAID|MEDICAID|N/A|AL MEDICAID|N/A|"Tier2,PA|NPF"||||||||||

Scott,

Would this satisfy the condition "the script should check the second and the third column if null then default those to ND" ?? Smilie

I guess not.

Um. Err.

Maybe I should have read the whole question!

I like pamu's solution Smilie

Thanks!

I like concept of pamu's solution also, but it has a few problems:
  1. If there is an empty line or a line with only one field, fields 2 and 3 will be set to a space; not "ND".
  2. If there is a line with three fields in the input file, field 3 will be set to a space no matter what it originally contained.
  3. If a line has four to twenty fields (inclusive), the contents of the last field present will be replaced by a space.
I think the following does what was requested:
Code:
awk 'BEGIN{FS = OFS = "|"}
{       if(NF == 0) $1 = " "
        $2 = $2 ? $2 : "ND"
        $3 = $3 ? $3 : "ND"
        for(i = NF+1; i <= 20; i++) $i = " "
        print
}' file
