need help with git show :1:...

I remember this working for me in the not too distant past.  
I'm using git version 1.6.1.3.  Perhaps it was an older version of git
when it worked for me.

quadra% ls -l src/c/sock.c
-rw-r--r-- 1 layer fi 57909 Mar  9 13:32 src/c/sock.c
quadra% git show :2:src/c/sock.c
fatal: ambiguous argument ':2:src/c/sock.c': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
quadra% git show :1:c/sock.c
fatal: ambiguous argument ':1:c/sock.c': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
quadra% git show :1:sock.c
fatal: ambiguous argument ':1:sock.c': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
quadra% git show :1:/src/c/sock.c
fatal: ambiguous argument ':1:/src/c/sock.c': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions




If I cd to "src/c" and do "git show :1:sock.c" the same thing happens.

Thanks.

I didn't make it clear, but I am in the process of resolve conflicts
from a merge in the repo where those commands were executed.

Does the file have conflicts?  Try
  $ git ls-files -s src/c/sock.c
and report what the output is.

If it doesn't have conflicts, but the file is tracked by git, using
stage 0 should work:
  $ git show :0:src/c/sock.c

Yes, it did have conflicts.  I resolved the conflicts via editing, but
want to look at the other versions before finalizing the edits.

quadra% git ls-files -s src/c/sock.c
100644 ef6c9b94c678dc79760edfd15a0796b3726b76f6 0	src/c/sock.c
quadra% 

Elijah, thanks for replying.

That suggests that the file is not unmerged, i.e. that there aren't
any remaining conflicts.  This explains why your commands wouldn't
work unless you used stage 0 instead of 1 or 2.  Now, why there
weren't conflicts when you thought there were?  I have no idea, unless
perhaps you did a stray git add src/c/sock.c.

Hope that helps,
Elijah

It was several of weeks ago that I started this merge, and I remember
playing with git show then and it worki.  I might have overwriten
the file with one of the show's and done manual editing that way.  I
don't know if this makes a difference.

How can I redo the merge for just this file?  Is that possible?  I
think I'd definitely like to start over on *just this one file*.

Thanks.

Well, someone else probably knows a clever way to do this.  I don't,
but the following may help:

MERGE_REF=$(cat .git/MERGE_HEAD)
git show HEAD:src/c/sock.c > current-sock
git show $MERGE_REF:src/c/sock.c > other-sock
git show $(git merge-base $MERGE_REF HEAD):src/c/sock.c > base-sock
git merge-file current-sock other-sock base-sock

That'll redo the three way merge on src/c/sock.c (assuming no renames
or other special cases happened) and store the result in current-sock.
 You can then edit that file and when ready, move the result over
src/c/sock.c.

Did you mean this?

  git merge-file current-sock base-sock other-sock

The man page seems to indicate that.

Thanks.  This is a big help.

Oops, yeah, current then base then other, like the manpage says.
