Hi, you might be interested in the info below :

my test script:
"""
#!/bin/sh
[ $? -ne 0 ] && echo hi
"""

https://www.shellcheck.net says:
"""
Line 2:
[ $? -ne 0 ] && echo hi
  ^-- SC2181: Check exit code directly with e.g. 'if mycmd;', not
indirectly with $?.
"""

https://github.com/koalaman/shellcheck/wiki/SC2181 says:
"""
Running a command and then checking its exit status $? against 0 is
redundant. Instead of just checking the exit code of a command, it
checks the exit code of a command (e.g. [) that checks the exit code
of a command.
