You can also use cut :
Code:
cut -f2 -d, file

Thanks. AWK and Cut both are fine.

However, i have several files: file1,file2,file3...etc. which contains 4 column.

How can I make all those files contain in one column and filename will be same, using ONE AWK command?

file1,file2 four column change into one column file1,file2.

Code:
for i in *;do awk -F, {print $2} $i > $i.bk; mv $i.bk $i; done

Note : mv command is used, so your original file will be replace with one column

If you have GNU sed:
Code:
sed -ri.bak 's/,([^,]*$)?//g' infile*
