What command did git do with "git reset --har" -

i missed tab key before pressing enter on local git branch, ended executing:

git reset --har 

versus intended

git reset --hard 

usually git complains when running command appears mistyped. looked through --help git reset , found no args "h","a","r".

it seems have run hard reset, did run? or if ran "--hard" why?

additional info: sylvesterjakubowski$ git --version git version 1.7.12.4 (apple git-37) #on mountain lion.

this per gitcli doc page:

many commands allow long option "--option" abbreviated unique prefix (e.g. if there no other option name begins "opt", may able spell "--opt" invoke "--option" flag), should spell them out when writing scripts; later versions of git may introduce new option name shares same prefix, e.g. "--optimize", make short prefix used unique no longer unique.

also on same page:

commands support enhanced option parser accepts unique prefix of long option if spelled out, use caution. example, git commit --amen behaves if typed git commit --amend, true until later version of git introduces option shares same prefix, e.g `git commit --amenity" option.

so yeah, ran git reset --hard
