Re: [Trisquel-users] How to check MD5 in multiple folders with one command ?

[magicbanana]

As far as you wrote, 'md5sum' was called from the "subfloders" and you need  
to do the same when checking. Moreover, double quotes are needed for paths  
including spaces. Here is something that should work if called from the root  
of the hierarchy subtree containing the md5.txt files:
$ find "$PWD" -name md5.txt | while read dir; do cd "${dir%/*}" && md5sum -c  
md5.txt; done

I can explain it to you if you wish.
