%H
commit hash

%h
abbreviated commit hash

tree hash

%t
abbreviated tree hash

%P
parent hashes

%p
abbreviated parent hashes

%an
author name

%aN
author name (respecting .mailmap, see git-shortlog[1] or git-blame[1])

%ae
author email

%aE
author email (respecting .mailmap, see git-shortlog[1] or git-blame[1])

%al
author email local-part (the part before the @ sign)

%aD
author date, RFC2822 style

%ar
author date, relative

%at
author date, UNIX timestamp

%ai
author date, ISO 8601-like format

%aI
author date, strict ISO 8601 format

%as
author date, short format (YYYY-MM-DD)

%ah
author date, human style (like the --date=human option of git-rev-list[1])

%cn
committer name

%cN
committer name (respecting .mailmap, see git-shortlog[1] or git-blame[1])

%ce
committer email

%cE
committer email (respecting .mailmap, see git-shortlog[1] or git-blame[1])

%cl
committer email local-part (the part before the @ sign)

%cL

%cr
committer date, relative

%ct
committer date, UNIX timestamp

%ci
committer date, ISO 8601-like format

%cI
committer date, strict ISO 8601 format

%cs
committer date, short format (YYYY-MM-DD)

%ch
committer date, human style (like the --date=human option of git-rev-list[1])

%d
ref names, like the --decorate option of git-log[1]

%D
ref names without the " (", ")" wrapping.

%S
ref name given on the command line by which the commit was reached (like git log --source), only works with git log

%e
encoding

%s
subject

%f
sanitized subject line, suitable for a filename

%b
body

%B
raw body (unwrapped subject and body)

%N
commit notes

%GG
raw verification message from GPG for a signed commit

%G?
show "G" for a good (valid) signature, "B" for a bad signature, "U" for a good signature with unknown validity, "X" for a good signature that has expired, "Y" for a good signature made by an expired key, "R" for a good signature made by a revoked key, "E" if the signature cannot be checked (e.g. missing key) and "N" for no signature

%GS
show the name of the signer for a signed commit

%GK
show the key used to sign a signed commit

%GF
show the fingerprint of the key used to sign a signed commit

%GP
show the fingerprint of the primary key whose subkey was used to sign a signed commit

%GT
show the trust level for the key used to sign a signed commit

%gD
reflog selector, e.g., refs/stash@{1} or refs/stash@{2 minutes ago}; the format follows the rules described for the -g option. The portion before the @ is the refname as given on the command line (so git log -g refs/heads/master would yield refs/heads/master@{0}).

%gd
shortened reflog selector; same as %gD, but the refname portion is shortened for human readability (so refs/heads/master becomes just master).

%gn
reflog identity name

%gN
reflog identity name (respecting .mailmap, see git-shortlog[1] or git-blame[1])

%ge
reflog identity email

%gE
reflog identity email (respecting .mailmap, see git-shortlog[1] or git-blame[1])

%gs
reflog subject
