Go exec.Command（）-运行包含管道的命令

Question

The following works and prints the command output:

out, err := exec.Command("ps", "cax").Output()

but this one fails (with exit status 1):

out, err := exec.Command("ps", "cax | grep myapp").Output()

Any suggestions?

Answer 1

You could do:

out, err := exec.Command("bash", "-c", "ps cax | grep myapp").Output()
