I'm trying to make neofetch report that the uptime of my computer is 13.7 billion years, for an art project. I used awk to get the uptime from one invocation of the command (since uptime is constantly changing), and then tried using sed to replace the output of neofetch uptime with 13.7 billion years.
This works fine if I do it by myself in the terminal:
[nixos@nixos:~]$ neofetch uptime | sed 's/30 mins/13.7 billion years/'
uptime: 13.7 billion years
But when I try to do it with variables, it doesn't work:
neofetch uptime | sed 's/$(neofetch uptime | awk '/uptime:/ {print $2, $3, $4, $5}')/13.7 billion years/'
sed: can't read {print: No such file or directory
Edit:
neofetch uptime | sed "s/$(neofetch uptime | awk '/uptime:/ {print $2, $3, $4, $5}')/13.7 billion years/"
uptime: 14 mins
end Edit
Doing it with a script: (script.sh):
uptime_value=$(neofetch uptime | awk '/uptime:/ {print $2, $3, $4, $5}')
echo "Found uptime_value:"
echo ${uptime_value}
neofetch uptime | sed "s/${uptime_value}/13.7 billion years/"
Output:
Found uptime_value:
34 mins
uptime: 34 mins
What am I doing wrong?
From https://github.com/dylanaraps/neofetch/wiki/Customizing-Info and scanning the source, manipulating the output is unnecessary. You could just override the uptime function:
echo 'get_uptime(){ uptime="13.7 billion years"; }' >> $HOME/.config/neofetch/config.conf
After that, it should produce that text everywhere. For example, on my machine:
$ neofetch distro shell uptime --uptime_shorthand tiny
distro: Xubuntu 24.04.1 LTS x86_64
shell: bash 5.2.21
uptime: 13.7 billion years
