What is JuliaLang's equivalent to Python's sys.executable?

Question

I would like to retrieve the path of the currently running Julia interpreter from Julia. In Python, this can be achieved with sys.executable.

Answer 1

Base.julia_cmd() is probably what you need. It returns the full command line that was used to invoke the current julia process, with the default options spelled out. Base.julia_exename() returns the name of the executable.

julia> Base.julia_cmd()

/Users/aviks/dev/julia/julia5/usr/bin/julia -Cnative -J/usr/lib/julia/sys.dylib --compile=yes --depwarn=yes

julia> Base.julia_exename()
"julia"
