Full Discussion: Trap the EXIT_CODE from a script
Top Forums UNIX for Advanced & Expert Users Trap the EXIT_CODE from a script Post 303019064 by rbatte1 on Friday 22nd of June 2018 08:54:22 AM
Old 06-22-2018
Of course, renaming the original might cause problems. I had to intercept calls to usermod etc. on an old HPUX server once so we could log what was being called. The original (compiled) code was hard-linked for several functions (usermod, useradd, etc.) and reacted differently depending on what name was used to call it.


Perhaps we could suggest many ways of accomplishing this (e.g. with trap or other coding changes) but until we can see what is being called, we're all going to be stuck.


Assuming something checks the value of $? then you could simply add a : or true after the call that may get killed off. Of course, then you don't know when it may have genuinely failed. We need to see (enough of) your code to give you something useful.




Kind regards,
Robin
