Use the && control operator to combine two commands so that the second is run only if the first command returns a zero exit status.
使用&&控制操作符来组合两个命令，以便仅当第一个命令返回零退出状态时才运行第二个命令。
Run a command only if another command returns a zero exit status.
仅当另一个命令返回零退出状态时才运行某个命令。
The last thing to do is exit with a zero return code so that the trigger monitor will commit the GET it performed on the trigger message and wait for another.
最后需要做的事情是使用一个零返回码退出，以便触发器监控器提交它在触发器消息上执行的GET并等待另一条消息。
The exit value is not 0 (zero), as returned in function main.
这个退出值不是0(零)，如main函数中所返回的。
As the test man page states, the test command evaluates expression parameters and, if the expression value is True, returns a zero (True) exit value.
正如test的手册页指出的，test命令运算表达式参数的值，如果表达式的值是True，就返回零(True)退出值。
Errexit: if a command has an exit status of anything but 0 (zero), execute the err trap (if it is set and exists).
errexit：如果某个命令产生非0(零)的退出状态并且设置了err陷阱，则执行err陷阱并退出。
Similarly, the || control operator separates two commands and runs the second command only if the first command returns a non-zero exit status.
类似地，||控制操作符分隔两个命令，并且仅当第一个命令返回非零退出状态时才运行第二个命令。
The most important issue, of which the Fed is keenly aware, involves the exit strategy for avoiding inflation once the economy has improved and short-term nominal interest rates are no longer zero.
美联储敏锐地意识到：一旦经济改善和短期名义利率不再为零，最重要的问题是涉及避免通货膨胀的退出策略。
This is because as long as the connection is successful, the last exit status will be zero.
这是因为只要连接成功，最后的退出状态码就是零。
The exit strategy comes into play when and if the economy has improved and, hence, institutions no longer have an enormous demand for low-risk excess reserves that pay zero interest.
当且当经济改善和机构不再有对零利息的低风险超额准备金的大量需求，退出策略才能生效。
If the trace mode is not set to OFF (which is the default), then each entry, exit and non-zero SQL code will be logged in a global temp table with the following name and format.
如果跟踪模式没有被设为OFF(即默认情况)，那么将使用下面的名称和格式，把每个入口、出口和非零s QL代码都记录到一个全局临时表中。
Run a command only if another command returns a non-zero exit status.
仅当另一个命令返回非零退出状态时才运行某个命令。
If the decrement leaves threadcount at zero, we know that there are no threads running, so it's time to exit.
如果互斥量threadcount的值减小到了零，我们知道这时已经没有线程在运行了，该退出程序了。
If you set this variable, TCSH displays the exit status whenever a script or program returns a non-zero value, thereby indicating a potential error.
如果设置这个变量，那么当脚本或程序返回非零值时tcsh会显示退出状态，这会指出潜在的错误。
Notice that when you run the command, the if statement for the last exit status is never reached because the script exits upon a non-zero return status of the cp command.
注意，当您运行该命令时，实现最终的退出状态的if语句将永远无法满足条件，因为脚本在遇到cp命令的非零返回状态时将退出。
As stated in the definition, test returns a zero exit value if the expression value was True or a non-zero exit value (that is, 1).
根据定义，如果表达式值是True，那么test返回零退出值，否则返回非零退出值(即1)。
These factors make the die exit pressure, normal velocity and shear rate not to be zero, thus lead to problems including die swell and etc.
这些影响因素使得口模出口处压力、法向速度和剪切速率均不为零，从而引发离模膨胀等问题。
