Description Garrett Holmstrom 2015-04-24 23:23:08 UTC
Description of problem:

While looking through the bash completion file in dnf's git tree [1] I noticed the following snippet near the top of the file:

if [[ "$( readlink /usr/bin/dnf )" == "dnf-2" ]]; then
    alias dnf="dnf-2"
    alias python="python2"
    alias dnf="dnf-3"
    alias python="python3"

This is going to define a shell alias for "python" that can differ from the version of python residing at /usr/bin/python.  Needless to say, that is rather dangerous and probably not what that script is intended to do.

Version-Release number of selected component (if applicable):

Comment 1 Orion Poplawski 2015-04-27 15:28:13 UTC
It also shouldn't alias dnf - this causes problems when switching from dnf-2 to dnf-3 or vice-versa.

Comment 2 Honza Silhan 2015-04-28 10:23:56 UTC
Thanks for the report. The aliases were the intention inside the script.

Now it should not affect the rest of the shell.
