What is bash-static used for?
bash;static linking
You are probably referring to the .deb package bash-static which is a statically linked version of bash, which means that it is a stand-alone program that does not depend on anything else (especially libraries) on your disk.I have used it on two different occasions:Installed on servers so that I always have a working bash, even in catastrophic situations when ld.so or libc are not functioning (absent, corrupt, ill-configured, ...)Delivered to customers along with my own shell scripts, so that I'm sure they have the proper version of bash, since I was using some advanced features that were introduced with bash v4.3.
