I have a Canon camera mounted with gphotofs and I'm trying to essentially do an md5sum on all of the files, but I need to rename the files before I write them to my file, so sed is in the equation. However, if I pipe output to tee, echo, cat, or even just try to redirect with >, I get no output at all. Weird.

Here's what I'm running:

md5sum * | sed -e 's:\bJPG\b:jpg:' -e 's:\bMOV\b:mov:' -e 's:\bCR2\b:cr2:' | tee ~/Desktop/remote.md5sum

If I remove the final redirect to tee, it works. If not, it doesn't. Any ideas as to what could be going wrong?

I would begin by checking tee with type tee, and file /path/to/tee, path returned by type. – enzotib Aug 23 '11 at 6:19
Do you mean that the command ending with > ~/Desktop/remote.md5sum works? – rozcietrzewiacz Aug 23 '11 at 19:24
Nope, it doesn't work. No output redirection after sed works. – TK Kocheran Aug 24 '11 at 16:41
(Please use the @ if you are answering to a comment, I came back here by chance). OK, and how about the almost same thing - but with >> ~/Desktop/remote.md5sum? Does the file ~/Desktop/remote.md5sum already exist? – rozcietrzewiacz Aug 24 '11 at 17:58
@TKKocheran Just curious about what happened with this question? Was the issue resolved? – jw013 Jan 6 '12 at 2:42
