Plz help

awk  -F\| 'BEGIN{OFS=FS;}{$2=$2".";$3=$3".";}1' input_file

@msabhi: Thanks for the reply it works as expected.

GNU sed:

sed 's/|/.|/2g' file

Code:

awk  -F\| 'BEGIN{OFS=FS;}{$2=$2".";$3=$3".";}1' input_file 

Hi msabhi can you please let us know the meaning of putting 1 at the last of awk command.thanks in advance

Everything in awk has the form condition{action} . If the condition evaluates to 1 then the action is performed. If the condition is omitted then the default condition is 1, so the action is always performed. If the action is omitted then the default action is performed, which is {print $0} . In this case the condition is "1" so that evaluates to 1 and the action is omitted, therefore {print $0 } is performed, which is "print the entire record".

@abhigrkist :

Scrutinizer has said it all... and moreover his sed command is kewllllllllllll
