Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

custom scripts have no issue to pick up the environment variable but the custom services.

for e.g. adding a custom service in the container like:

pre_reqs() {
while read -r var; do
    [ -z "${!var}" ] && { echo "$(timestamp) | ${var} is empty or not set."; exit 1; }
done << EOF
QBITTORRENT_SERVER
QBITTORRENT_PORT
QBITTORRENT_USER
QBITTORRENT_PASS
VPN_GATEWAY
VPN_IF_NAME
CHECK_INTERVAL
NAT_LEASE_LIFETIME
EOF

return 0
}

Expected Behavior

No response

Is that the whole script? You need the shebang. https://github.com/linuxserver/docker-qbittorrent/blob/master/root/etc/s6-overlay/s6-rc.d/svc-qbittorrent/run#L1

Thanks you for your great help! I didn't realize that it needs a special interpreter rather than a regular shell.
