I have Ubuntu 20.04 installed on my desktop and recently installed Fedora 36 on my laptop. One think that I noticed is that if a type a command that doesn’t exist bash in Ubuntu 20.04 is more responsive compared to Fedora 36. For example in Ubuntu:
time abcd
Command 'abcd' not found, did you mean:
command 'bcd' from deb bsdgames (2.17-28build1)
command 'lbcd' from deb lbcd (3.5.2-3)
command 'ascd' from deb ascd (0.13.2-6)
command 'abcde' from deb abcde (2.9.3-1)
Try: sudo apt install <deb name>
real 0m0.051s
user 0m0.038s
sys 0m0.014s
while typing the same on Fedora:
time abcd
bash: abcd: command not found...
real 0m0.222s
user 0m0.017s
sys 0m0.020s
I don’t think this is related to the hardware of the computer since commands that exist take the same time to be execute (e.g. ls
). So what is the reason for such a noticeable different when command doesn’t exist?
