-rw-r--r--  1 root root     708632 Oct 27 12:47 3.1.13
-rw-------  1 root asterisk     18 Oct 27 12:44 .asterisk_history
-rw-------  1 root root       1610 Jul 25 15:55 .bash_history
-rw-r--r--  1 root root        571 Apr 11  2021 .bashrc
drwx------  3 root root       4096 Jul 14 13:00 .cache
drwxr-xr-x  4 root root       4096 Mar  3  2022 CodeIgniter-3.1.13
