Hi, I was installing a Perl Library via CPAN and something must have messed up some libraries during that process; this caused me issues because I couldn't launch many programs like Chrome. Whilst trying to resolve this issue I rather stupidly caused another and now I am having a rather major crisis. I have work I need to backup and I can't copy over to my cloud storage as I can't move any files, or rename any. Logging into Terminal just closes it immediately (With ITerm stating issues with the profile) and to top it all off I still can't open Chrome Anyway it's obvious what the issue is, changing something in /usr/libs is not advised and this has caused a major blowout, especially with Sudo every command I run gives me Code: sudo: unable to initialize PAM: No such file or directory A possible fix to this would be to take someone else's /usr/lib directory and put that in mine, now two questions: 1) Would copying someone else's Libraries fix my issue? 2) How would I copy them over if I can't move any files? Any speedy answer would be very very much appreciated, Thanks M EDIT: Ok this is more serious that I thought, I can't actually open up any programs now, if I close one I can never open it again, which means I cannot turn off my machine or close any windows.
