IBM Help with awk
Hi,

I have a stream of data like below:
Code:
abcdef1CXYZ1999PQR
ghijkl2MNOJ2012GHI

By using AWK and substr I am extracting the data, but I need to perform a substr based on the year. Say if Year is less than 2011 then I have to extract 9th char for output 3rd column and if Year is greater than or equal 2011, I have to extract 11th char for output 3rd column.

Code:
abc|def|C|1999
ghi|jkl|J|2012

Thanks.

Code:
awk '{X=11} substr($0,12,4)<2011{X=8}
    {print substr($0,1,3),substr($0,4,3),substr($0,X,1),substr($0,12,4)}' OFS="|" file

Unfortunately, your written request is not consistent with the sample you gave (Pos 9 as opposed to Pos 8). Try this, based on your written request:
Code:
$ awk  '{YR=$12$13$14$15; print $1$2$3, $4$5$6, YR<2012?$9:$11, YR}' FS="" OFS="|" file
abc|def|X|1999
ghi|jkl|J|2012

Let me tell in a clear way....
I have input file as:
Code:
C0000169811J4GL48K83W6854582003-11-19KJJH74200321796572863292268120001-01-01NY1NN 0001-01-01NN2012-10-15+0017.2O+0008.1N018861244178   60  NN11            001

C0005698011C3CDFBH5DD1580052012-10-19PFDP41201328423902466684666840001-01-01NY1NN 0001-01-01NN0001-01-01+0020.4 +0020.4N357526219604   00  NN01            001

My code is like below:
Code:
 awk 'BEGIN {OFS="\t"} {if  (substr($0,79,1) ~ "1" || substr($0,79,1) ~ "C" || substr($0,79,1) ~ "L" || substr($0,79,1) ~ "B" || substr($0,
79,1) ~ "E") print substr($0,02,09),
        substr($0,48,09),
        substr($0,28,10),
        substr($0,62,05),
        substr($0,67,10),
        substr($0,12,01),
        substr($0,93,01)}'

The above code is working fine, but the requirement is changed in retrieving substr($0,12,01), which is last but one :

Code:
{if (substr($0,28,4)  > 2011)
 print substr($0,15,01)
 else
 print substr($0,12,01)};

Need to integrate this functionality in the existing,
i.e; print with if condition

Is it possible to implement if-else condition in print stmt ?

Try (untested):
Code:
$ awk 'BEGIN  {OFS="\t"}
              {YR = substr($0,28,4), X = substr($0,79,1)}
       X ~ /[1CLBE]/ {print substr($0,02,09), 
               ...,
               substr($0, YR>2011?15:12, 1),
               ...}
       '

       '

Syntax error:

awk: cmd. line:1: ^ syntax error

I am trying as follows:

INPUT_FILE:

AWK:
Code:
cat INPUT_FILE | \
awk 'BEGIN {OFS="\t"} {if  (substr($0,79,1) ~ "1" || substr($0,79,1) ~ "C" || substr($0,79,1) ~ "L" || substr($0,79,1) ~ "B" || substr($0,
79,1) ~ "E") print substr($0,02,09),
        substr($0,48,09),
        substr($0,28,10),
        substr($0,62,05),
        substr($0,67,10),
 
{ if (substr($0,28,4)  > 2011)
 print substr($0,15,01)
 else
 print substr($0,12,01) };
 
        substr($0,93,01)}'

How to implement the if in PRINT, in AWK?

Replace , with ; here:
Code:
           {YR = substr($0,28,4), X = substr($0,79,1)}
                                ^--- ";"
