Top Forums Shell Programming and Scripting Compare content between two files Post 302744831 by Scrutinizer on Saturday 15th of December 2012 03:35:56 AM
To get unique results you could just run everything throught sort -u:
grep -xFf file1 file2 | sort -u

awk 'NR==FNR{A[$1]; next}$1 in A' file1 file2 | sort -u

Alternatively, one could make sure results only get printed once, for example:
awk 'NR==FNR{A[$1]++; next}$1 in A{delete A[$1]; print $1}' file1 file2


To get a count, you could use the -H opion you can run everything through | sort | uniq -c
grep -HxFf file1 file2 | sort | uniq -c

or to also specify the file name:
echo | grep -xFf infile1904 infile1904b - | sort | uniq -c

To get exactly the result you specified, it would need to be something like this:
awk '
  $1 in A{
    for(i in T)printf "%s: %s , repeated %d times\n", FILENAME,i,T[i]
' file1 file2
