I would like to get the number of recharge cycles using bash (terminal commands). I understand the following command will display all of the battery data, but I want the cycle count on its own

ioreg -l -w0 |grep Capacity

I use the following command to get the battery percentage, so I imagine it can be modified slightly to get the cycle count instead;

ioreg -l | awk '$3~/Capacity/{c[$3]=$5}END{OFMT="%.3f";max=c["\"MaxCapacity\""];print(max>0?100*c["\"CurrentCapacity\""]/max:"?")}'

I'm new to bash, so I'm not completely sure how that code works, or how I'd adapt it for my needs.

Any help would be appreciated. Thanks.

Something like

system_profiler SPPowerDataType | grep "Cycle Count" | awk '{print $3}'

should do the job.

    How about battery condition? – BenSmith Feb 2 '17 at 22:16

    @BenSmith system_profiler SPPowerDataType | grep "Condition" | awk '{print $2}' will get you the battery condition – joni Apr 8 '18 at 5:29
