Ubuntu bash

In the terminal running the long running command, just type say done and hit enter. When the long running command finishes, shell will take what you typed as the next command to run. This...

finally solved. I am running a 64-bit machine and a 32-bit Skype, so I just installed the libpulse 32 bit version:

sudo apt-get install libpulse0:i386 is all...

I will assume that you want to keep a proper suffix on the filenames:

c=1; for f in *.jpg ; do mv "$f" "photo$c.jpg" ; c=$(($c+1)) ; done

Notes

...

To resolve these issues I ran

rm -rf /usr/lib/x86_64-linux-gnu/libvlccore.so.9.0.0
apt-get --purge --yes remove '*vlc*'

This heavy handed approach eventually...
