Quotes around $@ (and ${arr[@]}) protect against word splitting and other substitutions, but still retain the list of argument members (and other array members).
In contrast, with $* and ${arr[*]} the quotes would enforce one string.

pam-script
PAM-SCRIPT(7) Miscellaneous Information Manual PAM-SCRIPT(7)NAME
pam-script - a PAM module that can invoke scripts within the PAM stack.
SYNOPSIS
pam-script.so [onerr=(success|fail)][dir=/some/path/]
DESCRIPTION
pam-script allows you to execute scripts during authorization, passwd changes, and on session opening or closing.
Such scripts can perform necessary tasks or influence the outcome of the PAM stack. For example, if the following entry was included in
pam.conf
sshd auth required pam_script
then if the script, pam_script_auth, exits with a non-zero value this would cause the user to be denied SSH access to the machine.
OPTIONS
A summary of options is included below.
onerr=(success|fail)
the default behavior if the module can not find or execute the script. The default is to fail if the option is not given.
dir=/some/path/
where to find the pam-scripts to invoke for each of the various module-types as described below. The default is dir=/usr/share/lib-
pam-script if not given.
List of scripts
pam_script_auth
Executed under auth which handles the authentication stage of establishing the user via some challenge-response (i.e. username/pass-
word)
pam_script_acct
invoked under account module-type for non-authentication based account management.
pam_script_passwd
invoked under passwd for changing the password tokens.
pam_script_ses_open
invoked when a session is first opened.
pam_script_ses_close
run after a session is first closed.
All the scripts will be passed several environment variables: PAM_USER, PAM_RUSER, PAM_RHOST, PAM_SERVICE, PAM_AUTHTOK, PAM_TTY, and
PAM_TYPE referring to the module-type. The pam_script.so arguments in the pam.conf will be passed on the command line, which can be
used to modify the script behavior.
FILES
/lib/security/pam_script.so - the PAM module
/usr/share/libpam-script - where the scripts should be placed by default
VERSION
pam-script 1.1.5
