退出所有被称为KornShell（ksh）的脚本

KornShell（ksh）脚本如何退出/终止从另一个ksh脚本启动的所有进程

如果scriptA.ksh调用scriptB.ksh，那么下面的代码工作得足够好，但是有更好的解决方案吗

scriptA.ksh:

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#if error: exit this script (scriptC) and calling scripts (scriptA, scriptB)#
#kill ${PPID}
#exit 1

scriptB.ksh:

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#if error: exit this script (scriptC) and calling scripts (scriptA, scriptB)#
#kill ${PPID}
#exit 1

为了增加复杂性，如果scriptA调用scriptB而scriptB调用scriptC，那么如果scriptC中出现错误，如何退出所有三个脚本

scriptA.ksh:

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#if error: exit this script (scriptC) and calling scripts (scriptA, scriptB)#
#kill ${PPID}
#exit 1

scriptB.ksh:

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#if error: exit this script (scriptC) and calling scripts (scriptA, scriptB)#
#kill ${PPID}
#exit 1

scriptC.ksh:

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#call scriptBSnippet
scriptBSnippet.ksh ${a}

#if error: exit this script (scriptB) and calling script (scriptA)#
kill ${PPID}
exit 1

#if error: exit this script (scriptC) and calling scripts (scriptA, scriptB)#
#kill ${PPID}
#exit 1

杀死由同一脚本启动的所有进程是一种蛮力方法

最好在进程之间使用某种通信方法，使它们能够正常关闭

但是，如果所有进程都在同一进程组中，则可以向整个进程组发送信号：

kill -${Signal:?} -${Pgid:?}

请注意，在这种情况下需要两个参数。以

-

开头的单个参数始终被解释为信号

运行一些测试以查看哪些进程包含在进程组中

parent.sh：

Shell=ksh
($Shell -c :) || exit

$Shell child1.sh & pid1=$!

$Shell child2.sh & pid2=$!

$Shell child3.sh & pid3=$!

ps -o pid,sid,pgid,tty,cmd $PPID $$ $pid1 $pid2 $pid3
exit

child.sh：

sleep 50

如果从终端运行

parent.sh

，它将成为流程领导者

granny.sh：

Shell=ksh
($Shell -c :) || exit

$Shell parent.sh & 

wait
exit

如果您从另一个脚本

granny.sh

运行

parent.sh

，则该脚本将成为流程组长，并将在您使用

kill-SIG-PGID

方法时包含在内

这些ksh脚本（scriptA、scriptB、scriptC）应该尽可能地解耦，并且每个脚本应该有尽可能少的输入参数。此解决方案将需要添加输入参数…如果每个脚本都可以将自己放在同一个进程组（Pgid）中，那么这可能会起作用，因此了解如何做到这一点吗？这应该是默认设置。更新了答案以帮助您展示。这是一个ksh问题而不是sh问题：-）我尝试使用多个shell测试解决方案，以查看它们之间的差异。现已修复：-）
