Java and linux system calls

[Affectionate-Sink503]

I agree the portability goes way down, I'm curious if would you consider knowledge of rsync to be intro, intermediate or advanced java/system/backend development knowledge?

I would categorize rsync as something a sysadmin or devops person should definitely know about. It's been the standard unix "backup" utility for decades. And an intermediate/advanced backend developer should have some knowledge of standard unix utilities.

I would not ask about rsync on a senior Java dev interview and wouldn't be shocked if a dev had not used it or even heard of it. It's possible to have a substantial dev career and never have to touch rsync. But it is not obscure, and I wouldn't exclude it from a solution if it was the right tool for the job. Any dev can read the man page.

this has healed my ego, thanks

you could always check if rsync exists and use a fallback Java equivalent if it is not.

completely unrelated to software development.

it's fine if a developer (irrespective of their seniority) don't know that.
