Can I use sed command in lnav?

[zhangjun-xyz]

During checking the log files, sometimes I wanna substitute a string with another. I usually use sed to accomplish this. I typed this :eval :sed -i 's/A/B/, But it told me error: unknown command - sed. Why is that? And do I have other options?

I currently to do replace my log levels with Nerdfont icons and same with :bash -c ....

For some reason :sh -c gets executed, but then my fish shell kicks in and causes problems ahh
