what is the difference between filename and filename.txt
I can't find any directory /usr/lib or and directory or files for commands in my pc. But I can access them and I can go to these directories by terminal. But such directories are not present in my pc. I am using virtual box for running Ubuntu.
I have change directory by cd /usr/lib. Then I have display all the files in this directory by ls -all. Now I want to save the result in a file. So I enter the command: ls -all > filleinfo. But it shows me that bash: fileinfo: Permission denied. If I do the same in home directory, then it work fine, but when I change the directory it not work
