If I open a terminal and type, lets say
ls, the terminal just does nothing. It isn't frozen, because I can cancel the command, but it just doesn't return the result of the command. This happens for any terminal I now open.
Certain commands work, others don't:
- htop, pwd, cd, ps -aux -- all work
- ll, ls and df -h -- don't work
I have killed all my user programs/terminals I had open and still no joy. I really don't want to restart the machine because it has other programs running under other users.
Is this a known issue/what can I do to fix it?
This is CentOS 7.4
