    That depends on how it is run.

    If run from the bash command line, or from another bash script, it
    will be executed by bash.

    If run by at or cron (or pdksh), /bin/sh is used. Which in the
    case of linux, is still bash, but the startup files will not be
    read (see the INVOCATION section of the man page).
