Get md5sum without file name?

Question

I need to get the md5 sum of a file on AIX, but the md5sum program prints the sum followed by the name of the file.

How can I get the sum without the file name.

then gencha's answer should be sufficient...you can use any number of tools to split fields - awk, cut, whatever

md5sum < filename

This will give you an empty filename.

That outputs a - to represent stdin. – Dennis Williamson Nov 5 '10 at 15:53

This is what i use. Don't need cat though, just redirect md5sum < filename – Rich Homolka Nov 5 '10 at 16:53

Good point @Rich, I do like that better – heavyd Nov 5 '10 at 18:58

md5sum filename | awk '{print $1}'

That would be one way.

	That is what I was thinking, just was not sure how he was getting the md5 in the first place. – Chris Nov 5 '10 at 14:03
	@Chris I figured this was the way as he mentioned the md5sum program. – Oliver Salzburg Nov 5 '10 at 14:05
