您可以执行以下操作：
[[ $s = 'something' ]] && echo 'matched' || echo "didn't match" [[ $s == 'something' ]] && echo 'matched' || echo "didn't match" [[ $s != 'something' ]] && echo "didn't match" || echo "matched" [[ $s -eq 10 ]] && echo 'equal' || echo "not equal" (( $s == 10 )) && echo 'equal' || echo 'not equal'
一项针对出口状态的班轮测试：
command && echo 'exited with 0' || echo 'non 0 exit' cmd && cmd1 && echo 'previous cmds were successful' || echo 'one of them failed' cmd || cmd1 #If cmd fails try cmd1
