Extract a file from an old commit to a path outside my working directory

I have a working directory at ~/gitrepo/ (this is where .git folder is, and all my other files as usual).

I have an old commit whose SHA-1 hash I know. In it there was a file foo.cpp that I now want to bring back to another directory (just to not mess up my working tree), for instance here:

~/Desktop/foo.cpp

How to do this?

This is what I did to get an old copy of an Informix 4GL file. First, I copied re_trnfunc.4gl to re_trnfunc.4gl.sav, because I had never tried this before.

Then, I entered:

git log --shortstat --pretty

I looked for the commitment that corresponded to the comment that told me which version I wanted.

    Put in new re payment distro order, interest, charges, and principal.

 1 files changed, 34 insertions(+), 30 deletions(-)

Then I entered (as shown in @ДМИТРИЙ МАЛИКОВ 's answer)

git checkout 6fbe9303e7f80150fdf6abdc8f926a802f8a171e -- re_trnfunc.4gl

I examined the file, saved it elsewhere, and then needed to put re_trnfunc.4gl the way it was before the checkout.

I entered:

git reset HEAD re_trnfunc.4gl

I could have eliminated having to reset by checking out the file to a temp name after the -- in the

git checkout 6fbe9303e7f80150fdf6abdc8f926a802f8a171e -- temp_re_trnfunc.4gl

command.

You can find your commit on github website, and download the file you want from there.

git checkout SHA -- foo.cpp
cp foo.cpp ~/Descktop/foo.cpp

After that you'll have edited foo.cpp , so you may wanna revert it back with git reset or something.
