Adding file name to the counted data

Question

Suppose I have files similar to the following.

file 1

1,144931087,144931087,T,C  
16,89017167,89017167,C,G  
17,7330235,7330235,G,T  
17,10222478,10222478,C,T  

file 2

1,144931087,144931087,T,C
16,89017167,89017167,C,G
17,10222478,10222478,C,T

file 3

17,10222478,10222478,C,T  

I would like to find how many times duplicated values are present in each file, So ideally, the output would be like:

Output

2 1,144931087,144931087,T,C  
2 16,89017167,89017167,C,G  
3 17,10222478,10222478,C,T  
1 17,7330235,7330235,G,T 

I used the following command for counting the duplicates value.

sort Test1.csv Test2.csv Test3.csv | uniq --count

Now I wish to add the file name for the counted output. My desired output should look like this:

Test1 Test2 2 1,144931087,144931087,T,C  
Test1 Test2 2 16,89017167,89017167,C,G  
Test1 Test2 Test 3 3 17,10222478,10222478,C,T  
Test1 1 17,7330235,7330235,G,T  

Can anyone help me to get the desired output or can anyone suggest me a better way to get my desired output?

Answer 1

Using awk. Sorry about my clever file naming scheme:

$ awk '{
    a[$0]++                   # count hits
    b[$0]=b[$0] FILENAME " "  # store filenames
}
END {
    for(i in a)               
        print b[i] a[i],i     # output them
}' foo bar baz
foo bar 2 1,144931087,144931087,T,C
foo bar 2 16,89017167,89017167,C,G
foo bar baz 3 17,10222478,10222478,C,T
foo 1 17,7330235,7330235,G,T

UPDATED per comments:

$ awk 'BEGIN {
    FS=OFS=","
} 
{
    a[$1 OFS $2 OFS $3 OFS $4]++ 
    b[$1 OFS $2 OFS $3 OFS $4]=b[$1 OFS $2 OFS $3 OFS $4] FILENAME "|"
    c[$1 OFS $2 OFS $3 OFS $4]=$0                      # keep the last record with 
}                                                      # specific key combination 
END { 
    for(i in a) 
        print b[i] "," a[i],c[i]  
}' foo  bar baz
foo|bar|,2,16,89017167,89017167,C
foo|,1,17,7330235,7330235,G
foo|bar|,2,1,144931087,144931087,T
foo|bar|baz|,3,17,10222478,10222478,C
