I created 2 scripts like below <http://gnu-bash.2382.n7.nabble.com/file/t3303/Screenshot_20210516_163002.png>
Running the test1.sh with bash 5.1 will have different PPID printed by the last test2.sh call when it is executed in sub-shell. For bash 4.3, the script will output consistent PPID. <http://gnu-bash.2382.n7.nabble.com/file/t3303/Screenshot_20210516_163523.png> It looks like something had been changed regarding the sub-shell execution in later Bash versions? -- Sent from: http://gnu-bash.2382.n7.nabble.com/
