Re: Excluding files with grep

[DarkRick]

Hi Jian Wang-4,

I have a lot of files in different folders, and some of them are damaged. A
damaged file looks like a normal file in size,  i.e 300 Kb, but all the 300
Kb of the file is 00 in hexadecimal format.
I don't know exactly which files are damaged, so and I found this needing:
1. To list the files that are ok and exclude all damaged files (That are not
full of 00 in hexadecimal format), but that it is not useful because I need
to replace the damaged files, or
2. To list the files full of 00 in hexadecimal format

I tried the second choice with this sentence:
$ find / -type f -print | grep ^[1-9A-Za-z] 
It would return the files that doesn't contain the character set that I want
to remove, but it returns nothing.

Thanks a lot.
