Bash shell 脚本命令在通过 Bitrise 运行时乱序执行

Question

In the bitrise workflow's script step, I added following snippet:

adb shell ps | grep screenrecord | awk ‘{print $2}’ | xargs adb shell kill

Purpose is to kill the process called screenrecord that was started in a previous step and it works fine when I test it on my system. But when this workflow is triggered through bitrise, it fails with following logs:

What is the cause of this issue and how to fix it?

Answer 1

Most likely this is because awk is not outputting the process id. One possible workaround to try is the following:

adb shell ps | grep screenrecord | sed -E 's/[ ]+/ /g' | cut -d' ' -f2 | xargs adb shell kill

where the awk command has been substituted with sed (to remove the multiple spaces) and a cut one (to get the process id).
