vowpalwabbit - After update, which Vowpal Wabbit version am I running? -

i had year old version of vw i'm running terminal standard vw syntax. installed latest version, downloading git , running make. when run vw, running newer version of need update alias or else?

which vowpal wabbit running?

this shell dependent answer. shells should work:

which vw 

if you're using sh compatible shells bash, should work:

type vw 

which version it?

vw --version 

please don't use shell aliases switch between versions.

aliases aren't preserved across shell invocations, vw utilities such vw-hypersearch example, may not use version think using (because have misconceived vw alias set somewhere).

instead, need first 'install' (basically copy) vowpalwabbit/vw executable standard location (e.g. using make install same place ran make), make sure path includes directory installed vw in e.g. prepending /usr/local/bin it:

export path=/usr/local/bin:$path 

better: put above in ~/.bashrc (or equivalent) don't need repeatedly set when log in.
