The pipe operator '|' will pass the output of one command to an other:

$ ls | grep txt

In the example above  the output is passed from the ls command to the 
grep command and grep will search for the expression 'txt'.

The redirection  operator '>' will  redirect the output to a "file, the 
file could be:
- file descriptor
- null device (/dev/null)
- regular file

One '>' will create the file if it does not exist or if it exist '>' 
will truncate the file to zero size ("empty the file").
Two '>' will append to the file.

$ echo test > test.txt -- Only test will be in the file test.txt
$ echo test >> test.txt -- If text.txt already exist "test" will be 
added to the end of the file otherwise "test.txt" will be created with 
only "test" in it.
