I’m trying to run a simple bash script using Scheduled Tasks on a Synology NAS. It fails interpreting an argument as a file.

OS: DSM 7.1.1-42962 Update 6

The ‘user-defined script’ in Scheduled Tasks:

/bin/bash /volume1/backup/fossil/start_fossil.sh

start_fossil.sh:

#!/bin/bash
cd /volume1/@appstore/fossil-scm/bin
fossil server --port 8080 /volume1/backup/fossil/fossil --https

Output:
no such file: server

I don’t understand why the argument server is interpreted as a file. If I run the script with ./start_fossil.sh or bash start_fossil.sh it just works. It also works if I run the command directly in my shell. I tried several options with different quotes around the command or the arguments to no avail.

Any advice?
