But they give instructions like
This creates the ELF that is needed, and probably some .so files.
Why not put those inside a zip file for download, like with windows apps? Is there any reason why they need to be compiled by the user?
@FaheemMitha smartctl can tell you the total power-on hours, which is probably more important than the manufacture date. smartctl can also tell you other details. also, hdparm -i can give you info about your drive
@FaheemMitha - i haven't even been here very long, but in a year or two i've noticed a marked upturn in activity which i only guess is due to increased overall popularity of this website. i think possibly the cumulative knowledgebase here may have negligibly increased as a result, but i have a strong conviction that the average such is tolling the lower end of the bell curve.
people vote for what they understand, and, (as i consider it) inexplicably, the less they understand, the more they vote!
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; often written as SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs) that detects and reports on various indicators of drive reliability, with the intent of enabling the anticipation of hardware failures.
When S.M.A.R.T. data indicates a possible imminent drive failure, software running on the host system may notify the user so stored data can be copied to another storage device, preventing data loss, and the failing drive can be replaced.

Hard disk failures...
@deostroll No, because the $PATH available to a script is not the same as the one set in .bashrc. A better question is why they're setting PATH in .bashrc in the first place, but they are, so they do.
Scripts are run in a special shell that doesn't read the normal initialization files.
See man bash:
When bash is started non-interactively, to run a shell script, for
example, it looks for the variable BASH_ENV in the environment, expands
its value if it appears there, and uses the expanded value as the name
of a file to read and execute. Bash behaves as if the following com‐
mand were executed:
if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
but the value of the PATH variable is not used to search for the file‐
So by exporting PATH in the script, you only get the PATH from the script itself, none of the modifications a user might have made in their ~/.bashrc. For some reason, the author is ignoring ~/.profile.
@deostroll No, they would be needed to make sure that the script has the same environment (or almost) as the user has when running an interactive shell. I don't know if that's necessary here or not though.
@FaheemMitha - i dunno - what's rdiff-backup? it sounds like a differential backup of some kind. and so i guess it is similar in that way...? the review is good. if you want to know more about it though, just go to the website. the maintainer keeps a blog about it, and publishes all bounties he pays for bug reports.
@mikeserv Yes, rdiff-backupis an incremental backup thing. I used it around 10 years ago (how time flies) and was favorably impresded. Unfortunately the maintainers have all gone away, and it's now unmaintained.
@mikeserv Yes, I see.
@mikeserv Security is certainly an important aspect of data storage/backup.
I might give it a try for my email. On a trial basis.
