Here on Stack Exchange we often see answers on bash questions, that use tools other than the bash language, such as awk, sed, grep, etc.
These tools are specific in POSIX, so they should be available on most systems, but I was wondering if any systems exist where bash is available but not awk. Or does the availability of bash imply by necessity all POSIX tools?
Please consider all possible platforms, such as embedded systems, stripped down installations for working with old hardware, MS windows emulators, etc.
