Hi! Welcome to LQ!
More info on 'ecm' and it's 'update' program, and which 'distro'/OS you are running would help.
The -immediate is probably an option/'switch' to whatever the update program is. Try:
file /abc/ecm/bin/update
ls -l /abc/ecm/bin/update
Maybe query your package manager, to find out more about that 'update' program, like:
rpm -qf /abc/ecm/bin/update -OR- dpkg -S /abc/ecm/bin/update -OR- ...
(if 'update' is part of a pkg)
Here's info on option/'switch' (I mentioned above)
(the [[ -x /file ]] && cmd... checks that the file is executable, and, if so, runs cmd)
Let us know!
