How to avoid a shell script exiting on failure for particular commands
문제
The following script runs with the -e
option, so it will exit if any of the commands in it fail:
#!/bin/sh -e
command1 #script should fail if command1 fails
command2 #script should NOT fail if command2 fails
command3 #script should fail if command3 fails
How can I make the script not to fail on command2
?

You could turn off the setting as required:
#!/bin/sh
set -e
command1 #script should fail if command1 fails
set +e
command2 #script should NOT fail if command2 fails
set -e
command3 #script should fail if command3 fails
if you are running a command in shell that exits you can prevent it by running it inside a sub-shell:
(. script.sh)
