#7 dos2unix changes ownership and permissions on the file

[Anonymous]

When run by root user (or presumably any user with write privileges on a file), the original file ownership is lost along with original privileges depending on the umask of the user who runs the utility. This is a destructive change and can result in, for example, files that can't be opened by the original creator.

To illustrate:

$ ls -al /tmp/d2utest
-rw-r--r-- 1 cwilliam develop 16 Jun 24 10:24 /tmp/d2utest
$ su -
# dos2unix -q -o /tmp/d2utest
# ls -al /tmp/d2utest
-rw-r--r-- 1 root root 14 Jun 24 10:25 /tmp/d2utest

Contrast with:
# perl -pi -e 's/\r//' /tmp/d2utest
# ls -al /tmp/d2utest
-rw-r--r-- 1 cwilliam develop 14 Jun 24 10:37 /tmp/d2utest
