So i think I found a workaround solution: adding a few arguments before my rclone command and it seems to set the right permissions. I guess the best workaround would be to just find a way to set at a folder level any file created within that folder to always inherit a default permission of my choosing. Not sure if that is possible vs. adding commands before i run rclone
#!/bin/bash
RCLONE_LOG=/mnt/user/Personal/Logs/rclone_$(date +%Y%m%d_%H%M%S).txt && touch $RCLONE_LOG && chown nobody.users $RCLONE_LOG && rclone sync --delete-during --size-only --verbose --progress --no-update-modtime --transfers 8 --checkers 16 --contimeout 60s --timeout 300s --retries 3 --low-level-retries 10 --drive-chunk-size=64M --drive-upload-cutoff=64M --stats 1s --stats-file-name-length 0 --fast-list --drive-acknowledge-abuse --log-file $RCLONE_LOG "/mnt/user/MOV" "GD:GD/MOV"
