My official status seems a bit unclear (although I'm getting paid :-) ) but
unofficially I keep an eye on a lot of a customers servers. Ad-hoc shell
scripts still have similar structure as I know how to 'cut and paste'.
These scripts are run remotely via a 'homegrown' client-server setup. Many
should run on different UNIX environments and therefore have near the
beginning an OS check. Depending on that I can set PATH and anything else
important.
#
# check what type of OS this system runs on
#
OST=`uname -m`
case ${OST} in
"i386")
OST="SCO"
...
;;
"alpha")
OST="ALP"
...
;;
"ia64")
OST="HPU"
...
;;
*)
echo "unknown OS type ${OST} ... \c"
exit 1

The more I learn the better I understand I know nothing.
I have symlinks to all my files. I also have
special hooks that I run per
os and per host to pull in different configs when needed. Though in
recent years I've not needed it much. I used to do a lot for work like
this, but these days work envs are close to my home env, so there is
little
point.
I have a bunch of work-specific aliases which get picked up via:
if [ -f $HOME/.bashrc.local ] ; then
. $HOME/.bashrc.local
fi
I don't keep .bashrc.local under git control, since some of the paths
in those aliases might be considered Work-confidential, so I don't
want to push them out to a personal git repo.
I've been doing this since RCS days across 5
different SCMs... git makes
oopses so rare that the paranoia below seems overkill. Though for other
SCMs it would likely not be paranoid enough.
The backup directory isn't for paranoia, actually. It's so the first
time that I install my custom dotfiles on a particular machine, if
there is a prexisting dot-file, say, .profile, I copy it to the backup
directory before replacing it with a symlink to the dotfiles repo.
There might be some magic environment variables or PATH setup that is
unique to that particular system's default dot files, so I can take a
quick look at them and see if I might need to extend my generic dot
files, or maybe add something to the ~/.bashrc.local file, or some
such.
