I would like to stop all process if any of the script got errors?. If for example script1 works fine will continue script2, then if the script2 got errors, The bash should stop and will no continue to script3.
If it issues a return code, this will be in the variable $? until you do something else. You can test for that:-
Code:
:
:
scripts2
if [ $? -ne 0 ]
then
any abort action or message
exit
fi
script3
:
:
You can make your script exit with a non-zero return code by putting in exit 5 or whatever integer value you want (within reason)
Another way to do this is to make them dependant on each other with the && operator. This will move to the next if the return code is zero but quit that statement (carries on the the overall script) if any one of them fails:-
-e Exit immediately if a pipeline (which may consist of a single simple command), a list, or a compound command (see SHELL GRAMMAR above), exits with a
non-zero status. The shell does not exit if the command that fails is part of the command list immediately following a while or until keyword, part of
the test following the if or elif reserved words, part of any command executed in a && or || list except the command following the final && or ||, any
command in a pipeline but the last, or if the command's return value is being inverted with !. If a compound command other than a subshell returns a
non-zero status because a command failed while -e was being ignored, the shell does not exit. A trap on ERR, if set, is executed before the shell
exits. This option applies to the shell environment and each subshell environment separately (see COMMAND EXECUTION ENVIRONMENT above), and may cause
subshells to exit before executing all the commands in the subshell.
