The stat(2) manual addresses the support for nanosecond resolution for the timestamp fields, but it doesn't look trivial to test their presence or their names in a program intended to be portable: as many as four feature test macro names (_BSD_SOURCE, _SVID_SOURCE, _POSIX_C_SOURCE, _XOPEN_SOURCE) are mentioned.
I have a linux script job that is made up of 7 scripts in total to complete the job.
There are about 60 Variables defined at the start of each script.
These variables will be constant & identical in each of the 7 scrips.
The problem I have is that when I am working on the scripts, I have to copy paste all variables to all scripts each time I update or modify variable(s)
