root at nikos [~]# ls -al /usr/bin/python*
-rwxr-xr-x 3 root root 4864 Feb 22 02:00 /usr/bin/python*
lrwxrwxrwx 1 root root    6 Apr  5 20:34 /usr/bin/python2 -> python*
-rwxr-xr-x 3 root root 4864 Feb 22 02:00 /usr/bin/python2.6*
-rwxr-xr-x 1 root root 1418 Feb 22 02:00 /usr/bin/python2.6-config*
lrwxrwxrwx 1 root root   24 Apr  7 22:10 /usr/bin/python3 -> /opt/python3/bin/python3*
lrwxrwxrwx 1 root root   16 Apr  5 20:35 /usr/bin/python-config -> python2.6-config*
root at nikos [~]#
