I restarted my kubuntu machine - from the menu
leave->restart if that matters. Normally my terminal windows are brought up automatically after a reboot but this time my prompt was wrong and a bunch of other bizarre things.
Now /bin/sh is a link to /bin/dash and dash seems to have been loaded but suddenly it is a lot dumber than it was before the reboot. Now it doesn't recognize what
shopt is. When I try to dot execute my profile (
. ~/.bash_profile) I get error like
/bin/sh: 28: /etc/bash_completion: [[: not found. On the command line command completion does not work nor the up & down keys for command history.
I have not knowingly downloaded any packages that should have messed with this. Is there a valid reason why this should suddenly start happening.
Now I executed
/bin/bash from the command lines of my terminals and all seems to be well but this does not explain what is wrong with
bash is allegedly heavier than dash and since I open 20 or so terminals I would like to avoid that overhead if it is true.
Thank you for any insights into this.
