Hi,
Thanks for keeping such a help-full platform active and live always.
I am new to this forum and to unix also.
Want to know how to count the repetition of a field in a file. Anything of awk, sed, perl, shell script, solution are welcomed.
Input File------------------
abc,12345
pqr,51223
mno,72121
stu,34567
aaa,12345
pqp,11224
plm,72121
zxy,88888
fgh,12345
jkl,88888
Output File-----------------
abc,12345,3
pqr,51223,1
mno,72121,2
stu,34567,1
aaa,12345,3
pqp,11224,1
plm,72121,2
zxy,88888,2
fgh,12345,3
jkl,88888,2
As 12345 is repeated 3 times in files as second field, so wherever it is "3" is suffixed as last field.
Thanks for the solution in advance.
