I'm asking 'cause I don't really know.
What's the difference between a pipe "|" and sending the result
somewhere ">" ?
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.
