md5sum progress indicator

Ianmcc · 12-21-2004, 05:50 PM

hi just looking for any way to persuade md5sum to tell me how far through the file its checking. Ive made some automatic hard drive backup/restore scripts and need a progress indicator of some sort to say how far through the 5Gb or so image files the checker has got.

Ive seen programs like awesum and I'm going to look into them but I'd realy rather just have the raw data to make my own progress indicator arround that.

thanks in advance

md5sum doesn't have a lot of options and they probably don't expect anyone to sit around and watch for progress. I just go to the directory where the new iso images have been downloaded to and run the command: md5sum *.iso . Come back later....
I save the downloaded md5sum in a file called md5 and compare it to the results with the command: cat md5

thanks for the response. I'm not having any problems making and checking the files. But the application I'm writing needs a progress indicator as md5summing 5Gb of gzipped backup files takes a few minutes and the end users are wondering if its crashed or not (aparently a message telling them to wait isnt enough) any other ideas? I can happily go with a different checksum program if need be.

I've recently had the same question; here's what you can do:

Code:

pv backup.tar.bz2 |md5sum

pv will output a nice progress bar to stderr.

(I know this is a very old thread; but I hope someone will find this useful.)
