I am confused how md5sum --check
is supposed to work:
$ man md5sum
-c, --check
read MD5 sums from the FILEs and check them
I have a file, I can pipe it to md5sum
:
$ cat file | md5sum
44693b9ef883e231cd9f90f737acd58f -
When I want to check the integrity of the file tomorrow, how can I check if the
md5sum is still 44693b9ef883e231cd9f90f737acd58f
?
Note
cat file
might be a stream. So I want to use the pipe as in my example, not md5sum file
.
