Summary: When running “show interfaces” via script, it outputs properly when run as my regular user, but not as root, which is what Task Scheduler runs as.
I’ve confirmed this works properly on 1.2.5 (lts built via docker), but not on the latest 1.3-rolling.
Script:
#!/bin/vbash
source /opt/vyatta/etc/functions/script-template
echo $(date) >> /config/scripts/log-shInterfaces.log
echo $(id) >> /config/scripts/log-shInterfaces.log
echo $(run show interfaces) >> /config/scripts/log-shInterfaces.log
Output when run via bash in the CLI:
ryanb@vyos:~$ tail -f /config/scripts/log-shInterfaces.log

Task scheduler config commands, if it matters:
set system task-scheduler task test executable path /config/scripts/shInterfaces.sh
set system task-scheduler task test interval 1m
