I need to add the following alias line in my vnc script_wrapper configuration so that it will dynamically set a different GPU per session
script_wrapper: |
module purge
export PATH="/opt/TurboVNC/bin:$PATH"
export WEBSOCKIFY_CMD="/usr/bin/websockify"
alias vglrun='/usr/bin/vglrun -d :0.$(( ${port:-0} % $(lspci | grep NVIDIA | wc -l)))'
%s
this create issue when submitting the request “malformed format string - %$”
I’ve tried to escaped the $ and % by adding \ in front of them, but there is always an error "malformed format string - %"
How to escape these chars or how to be able to add $ and % chars ?
Thank you
use %%
for a single %
to display.
irb(main):019:0> sprintf("lias vglrun='/usr/bin/vglrun -d :0.$(( ${port:-0} % $(lspci | grep NVIDIA | wc -l)))'")

Thank you, it works like a charm. But my alias is not set, so I will add this in /etc/profile.d
