Can you post the output of the following (with the thumbdrive "jon" plugged in)
Code:
sudo find /media/jon -iregex ".*boot.*\.sh$" -exec ls -l {} \;
(This oneliner will try to find anything named close to that filename and let us know the permissions of anything it finds)
((more detailed description of oneliner:
find something
under the directory
"/media/jon"
that matches thecase-
insensitive
regular
expression ".*boot.*\.sh$"
(
.(any non-EOL character)
*(0 or more times)
boot(the letters "boot")
.*(0 or more of any character)
\.(escape-period, in other words, an actual '.' character)
sh(the characters "sh")
$(the end of the line, the "enter" character)
On any filename that matches that
iregex,
execute the following command (replacing
{} with the match's full path):
ls -l {}))
