In Linux everything that start with a .
is hidden.
So to access that...
In terminal use ls -la
amit@tapas:~/temp/time$ ls
amit@tapas:~/temp/time$ touch .somefile
amit@tapas:~/temp/time$ touch anotherfile
amit@tapas:~/temp/time$ ls
anotherfile
amit@tapas:~/temp/time$ ls -la
total 8
drwxrwxr-x 2 amit amit 4096 May 13 18:14 .
drwxr-xr-x 15 amit amit 4096 May 7 18:05 ..
-rw-rw-r-- 1 amit amit 0 May 13 18:14 anotherfile
-rw-rw-r-- 1 amit amit 0 May 13 18:14 .somefile
amit@tapas:~/temp/time$
In GUI like nautilus,you can hit cntrl + h
to show hidden files
