need to convert the above as below:-

Code:
ABC,DEF,
GHI1
GHI2
GHI3,
JKL,MNO,
PQR1
PQR2
PQR3,
STU

i have tried using code as:-

Code:
echo "ABC,DEF,GHI,JKL,MNO,PQR,STU"| sed 's/GHI/GHI1\nGHI2\n/g'

Code:

Hello Jassi,

Not sure about your logic but as per your output following may help you in same.
Code:
 awk -vone=1 -vtwo=2 -vthree=3 -F, '{for(i=1;i<=NF;i++){A=i%3==0?A ORS $i one ORS $i two ORS $i three ORS:A=A?A OFS $i:$i}} END{gsub(/^$/,X,A);gsub(/\n\,/,",\n",A);print A}'  OFS=,  Input_file

Output will be as follows.
Code:
ABC,DEF
GHI1
GHI2
GHI3,
JKL,MNO
PQR1
PQR2
PQR3,
STU

Hope this helps.


Thanks,
R. Singh

Standard sed does not understand \n in the replacement part, you need to use a hard newline instead:

Code:
$ echo "ABC,DEF,GHI,JKL,MNO,PQR,STU"| sed 's/GHI/\
GHI1\
GHI2\
GHI3/g'
