Thanks. It was solved by rewriting it in another way:

also, that's offtopic from the point of your question, regarding escape characters, but i'd suggest to use short load average value instead of momentary utilization %: bash -c 'echo scale=2\; $(cat /proc/loadavg | cut -d" " -f1) / $(nproc) | bc | sed "s/^\./0./g"'or, to display it as %: bash -c 'echo scale=2\; $(cat /proc/loadavg | cut -d" " -f1) / $(nproc) "*" 100 | bc | sed "s/^\./0./g"'100% would mean full utilization of all cpus/cores, and >100% would mean that amount of processes is more than current cpus could handle, so some of them are queued |

Yes yes, from the terminal it works for me too. But I meant from inside awesomewm where it doens't work! |

also, better use table instead of string for command: https://awesomewm.org/doc/api/classes/awful.widget.watch.html#awful.widget.watch:new |

btw i just noticed that scale= parameter in bc affecting not just display of the value, but also computation precision, so the better way do it like that: |

I have the following command to display CPU utilisation:
top -bn1 | grep "Cpu(s)" | sed "s/.*, *\([0-9.]*\)%* id.*/\1/" | awk '{print 100 - $1"%"}'I can run it from terminal like so:
bash -c "top -bn1 | grep Cpu\\(s\\) | sed --expression=\"s/.*, *\\([0-9.]*\\)%* id.*/\1/\""But when I put it inside awesome, I get an empty string:
myCPUusage = awful.widget.watch('bash -c "top -bn1 | grep Cpu\\(s\\) | sed \"s/.*, *\\([0-9.]*\\)%* id.*/\1/\""', 1)Is there an alternative way of evaluating complex commands?
