I have no idea what APFS is but I have been using Unix shell scripts
since before I bought a NeXT computer many years ago. I still use them,
primarily KSH and AWK scripts, to process ASCII files. Since my current
computer has an SSD drive, and apparently, there is no option but to use
APFS with an SSD, I need to know if my Unix stuff will continue to work.
Yes, it will.
In fact, IIRC, it should work better, since APFS is case sensitive, as
That hasn't changed.
As with HFS+, APFS has variants which are case-sensitve and
iOS devices use the case sensitive APFS variant (always), same as
versions/devices which are still using HFS+.
Macs default to using the case insenstive APFS variant, but you can
choose to create/erase a volume using case sensitive APFS. (As usual,
Adobe software users should avoid case sensitive file systems because
Adobe still can't get it right.)
One nice feature of APFS is that an APFS container can contain multiple
volumes which share free space, which means if you need a case sensitive
file system for a small number of things, it is easy to create a case
sensitive volume just for that purpse, while leaving the main volume
case insensitive, and not worry about the pain of resizing partitions if
you guess space requirements wrong.
