Formatting port scan output
I need to format port scan output for input into another app.

This is what I have;

Code:
1025/tcp
1521/tcp
2301/tcp
2381/tcp
3191/tcp
3389/tcp
5938/tcp
47001/tcp
54321/tcp
21/tcp
80/tcp
135/tcp
139/tcp
445/tcp
1025/tcp

I want to chop the "/tcp" off, run it through uniq so that I only have the unique ports and then stack the output like below comma separated

Code:
1521, 2301, 2381, 3191, 3389, 5938, 47001, 54321, 21

Thanks!

Something like...
Code:
$ cut -d'/' -f1 < sample4.txt | sort -n | uniq -u | tr "\n" ","
21,80,135,139,445,1521,2301,2381,3191,3389,5938,47001,54321,

Another approach:
Code:
awk -F\/ '{s=s?s ", " $1:$1}END{print s}' file
