In some circumstances, I need to make an official alias for a set of command, which acts just the same as the original software. Like:

alias ipython3="source /Users/zen1/miniconda2/bin/activate py3k; ipython; source /Users/zen1/miniconda2/bin/deactivate;"

But as I was lazy, I'd like to use another alias for alias ipython3, let it be ipy3, I could do it by just copying ipython3's content. But that would be too clumsy.

Is there some magic_func so that alias ipy3=magic_func("ipython3") can get the alias content of ipython3 when using ipy3?

PS: ipython3 should be kept is because it is the official command to trigger ipython for python 3, which can't be installed properly on my computer.

  • Wow, this means alias for alias is internally support by bash? Never thought about it. As ipy3 is under ipython3, it will works, right? Commented Dec 25, 2015 at 8:02

    @Zen You can even control that: alias ipy3='"ipython3"' would not try a second level alias replacement; using "ipy3" instead of "ipy3 would avaoid the first level replacement. Furthermore you can use aliases for parameters if the earlier alias value ends with a space: alias ech="echo foo "; alias text="bar baz"; ech text Commented Dec 25, 2015 at 13:06
