awk Problem while insert null field to file
Dear All,

I have the following input file. I want to replace data with null values.

I/P File:
9022334455|2008-12-06 06:10:21|2|Error@@@|esoo8erp|
9024334432|2008-12-06 08:40:59|6|Error@@@|6y2o8e6r|

O/P File:

9022334455||2||esoo8erp|
9024334432||6||6y2o8e6r|


Code:
awk -F "|" 'BEGIN{OFS="|"}{$2=" ";$4=" ";print}' i/pfile > out.file

Error:
awk: syntax error near line 1
awk: bailing out near line 1

How can i replace the data with null values ??

Thanks&Regards
Hanuma

use nawk or /usr/xpg4/bin/awk on Solaris
Code:
awk -F "|" 'BEGIN{OFS="|"}{$2="";$4="";print}'  i/pfile > out.file
