I want git to list all tags along with the full annotation or commit message. Something like this is close:

git tag -n5

This does exactly what I want except that it will only show up to the first 5 lines of the tag message.

I guess I can just use a very large number. What is the highest number I can use here? Is it the same on every computer?

UPDATE: I have had much time to think about this, and now I think I don't necessarily want to show the entirety of each message if some of them are extraordinarily long. I didn't really have any particular need that required me to see massive messages (other than my own propensity to be long winded in everything I write, including tag messages). I just didn't like the idea that it was not necessarily going to show me the whole message, as that made me feel like it was hiding information from me. But too much information can also be a bad thing.

Try this it will list all the tags along with annotations & 9 lines of message for every tag:

git tag -n9

can also use

git tag -l -n9

if specific tags are to list:

git tag -l -n9 v3.*

(e.g, above command will only display tags starting with "v3.")

-l , --list List tags with names that match the given pattern (or all if no pattern is given). Running "git tag" without arguments also lists all tags. The pattern is a shell wildcard (i.e., matched using fnmatch(3)). Multiple patterns may be given; if any of them matches, the tag is shown.
