who | awk '{print $1}' > file.txt
sort file.txt | uniq > file.txt
echo ' ' > results.txt
w > file2.txt
for i in `cat file.txt`
do
x=`grep -c $i file2.txt`
echo $x $i >> results.txt
done
sort -r results.txt > results2.txt
head -10 results2.txt > results.txt
This was my version and my teacher suggested i do it in one line.
So it's back to the drawing board

ATR_analysis - analyse a smart card ATR SYNOPSIS
ATR_analysis [ATRstring] DESCRIPTION
ATR_analysis is used to parse the ATR (Answer To Reset) sent by a smart card. The command also tries to find the card model using an ATR database stored in a text file smartcard_list.txt. The smartcard_list.txt file is searched in ./, /usr/local/pcsc/ and /usr/share/pcsc/ directories. Exemple: $ ATR_analysis '3B A7 00 40 18 80 65 A2 08 01 01 52' ATR: 3B A7 00 40 18 80 65 A2 08 01 01 52 + TS = 3B --> Direct Convention + T0 = A7, Y(1): 1010, K: 7 (historical bytes) TB(1) = 00 --> Programming Param P: 0, I: 0 TD(1) = 40 --> Y(i+1) = 0100, Protocol T = 0 ----- TC(2) = 18 --> Work waiting time: 960 x 24 x (Fi/F) + Historical bytes: 80 65 A2 08 01 01 52 Possibly identified card: 3B A7 00 40 18 80 65 A2 08 01 01 52 Gemplus GPK8000 BUGS
Maybe many bugs since I am not a ISO 7816 expert. FILES
