Shell Programming and Scripting

Hi Everyone,

I have a flat file of 1000 unique records like following : For eg

Andy,Flower,201-987-0000,12/23/01
Andrew,Smith,101-387-3400,11/12/01
Ani,Ross,401-757-8640,10/4/01
Rich,Finny,245-308-0000,2/27/06
Craig,Ford,842-094-8740,1/3/04
.
.
.
.
.
.

Now I want to duplicate each row 3 times. How shall I do ?

Please advice

Ganesh,

I'm sure that would be better solution that what I have below:
---------------------------------------------------------
while true
do

read record
if [ "$record" = "" ]
  then
    break

fi

echo $record >> ./outputfile
echo $record >> ./outputfile
echo $record >> ./outputfile

done < ./inputfile

### if the file name has to be changed :

rm ./inputfile
mv outputfile inputfile

--------------------------------------------------------------

awk ' 1 ; 1 ; 1' file
4

this could be one of the option..

{ rm -f infile && awk '{ for (i=0;i<3; i++) { print $0 } }' > infile; } < infile

sed "s/.*/&\\
&\\
&/" file

Thank you to all gurus for your time.

one more,

perl -e 'while (<>) { print $_, $_, $_ }' file

Another sed solution :

sed -n '/./{p;p;p;}' file

sed '/./{p;p;}' file

My sed command was based on hemangjani solution which doesn't output empty lines.
That wasn't an requirement, i read initial post without attention.
A solution even simpler :

sed 'p;p' file
