When you need to grep out some part of an output that appear several times, but you only want the one after x.
Go for sed , like this
sensors | sed '0,/amdgpu/d' | grep -m 1 fan1
It drops everything from line 0, after running the sensors command, including the first line that contains amdgpu. Then grabs a single line containing fan1, with grep -m 1.
Super useful if fan1 appears multiple times in the output.
What does the command do? This command in particular grabs the fanspeed of my gpu’s fans, which I also use as a case fan for intake.
