So, you might be wondering, where
 is this history information actually stored? 
Check out the 
.bash_history
 file, which is found in your home directory (or 
/root
 
for the 
root
 user). When you exit your shell, your history is copied to that file. If you 
remove that file, you're effectively clearing your history. I don't recommend you 
make a habit of that, though. Having a history of commands is very useful, especially 
when you may not remember how you solved a problem last time. History in Bash 
can save you from looking up a command again. To find out more about what the 
history
 command can do, check out its man page with 
man history
.
Learning new tricks with the command line that allow me to work more efficiently is 
a great feeling, at least for me. In the next section, we'll explore some useful tricks we 
can utilize while working with the shell.
