如何检查 bash 脚本是否是由 GUI 中的“在终端中运行”启动的？

我运行 bash 脚本。我想从终端运行它们，并从 GUI 中使用“在终端中运行”运行它们，并在运行交互式后离开bash。这里解释了简单地查看输出： 添加read -rn1。

问题X：
我想要一个“干净”的解决方案，在最后与 bash 具有相同的终端，exit如果脚本从终端运行并且从 GUI 运行，我可以用一个终端关闭。我可以添加bash -i，但如果从终端运行，则需要两个exit才能关闭终端。exec bash -i结果相同。

脚本中有没有办法检查它是否是通过“在终端中运行”从 GUI 启动的？

ps aux | grep aaaa # while script started from GUI was running
mint       53293  0.1  0.0  11216  3356 pts/3    Ss+  21:58   0:00 /bin/bash /home/mint/aaaaa.sh

注意到与从终端启动的区别是Ss+代替S+。

我假设你的 bash 脚本被命名为/path/to/mybashscript.sh

用于ps查找mybashscript.sh（$0如果在脚本内运行）；包括state/stat用于标识特定状态的列：

ps --sort +pid -eo pid,stat,command | grep "$0" | head -1 | awk '{print $2}' | grep "s"

或另一种过滤行的方法grep：

ps -eo pid,stat,command | grep "$0" | grep -v grep | awk '{print $2}' | grep "s"

从您的评论来看，差异是由于添加了s：s is a session leader对于 GUI 方式，Ubuntu 没有那种从文件管理器启动脚本进行检查的方式。

从man ps，状态代码如下：

PROCESS STATE CODES
   Here are the different values that the s, stat and state output specifiers (header "STAT" or "S") will display
   to describe the state of a process:

           D    uninterruptible sleep (usually IO)
           I    Idle kernel thread
           R    running or runnable (on run queue)
           S    interruptible sleep (waiting for an event to complete)
           T    stopped by job control signal
           t    stopped by debugger during the tracing
           W    paging (not valid since the 2.6.xx kernel)
           X    dead (should never be seen)
           Z    defunct ("zombie") process, terminated but not reaped by its parent

   For BSD formats and when the stat keyword is used, additional characters may be displayed:

           <    high-priority (not nice to other users)
           N    low-priority (nice to other users)
           L    has pages locked into memory (for real-time and custom IO)
           s    is a session leader
           l    is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
           +    is in the foreground process group
