<format

457 Pretty-print the contents of the commit logs in a given format,
458 where
<em><format
></em> can be one of
<em>oneline
</em>,
<em>short
</em>,
<em>medium
</em>,
459 <em>full
</em>,
<em>fuller
</em>,
<em>email
</em>,
<em>raw
</em> and
<em>format:
<string
></em>. See
460 the
"PRETTY FORMATS" section for some additional details for each
461 format. When omitted, the format defaults to
<em>medium
</em>.
463 <div class=
"paragraph"><p>Note: you can specify the default pretty format in the repository
464 configuration (see
<a href=
"git-config.html">git-config(
1)
</a>).
</p></div>
471 Instead of showing the full
40-byte hexadecimal commit object
472 name, show only a partial prefix. Non default number of
473 digits can be specified with
"--abbrev=<n>" (which also modifies
474 diff output, if it is displayed).
476 <div class=
"paragraph"><p>This should make
"--pretty=oneline" a whole lot more readable for
477 people using
80-column terminals.

484 Show the full
40-byte hexadecimal commit object name. This negates
485 <tt>--abbrev-commit
</tt> and those options which imply it such as
486 "--oneline". It also overrides the
<em>log.abbrevCommit
</em> variable.
494 This is a shorthand for
"--pretty=oneline --abbrev-commit"
499 --encoding[=
<encoding
>]
503 The commit objects record the encoding used for the log message
504 in their encoding header; this option can be used to tell the
505 command to re-code the commit log message in the encoding
506 preferred by the user. For non plumbing commands this
511 --notes[=

515 Show the notes (see
<a href=
"git-notes.html">git-notes(
1)
</a>) that annotate the
516 commit, when showing the commit log message. This is the default
517 for
<tt>git log
</tt>,
<tt>git show
</tt> and
<tt>git whatchanged
</tt> commands when
518 there is no
<tt>--pretty
</tt>,
<tt>--format
</tt> nor
<tt>--oneline
</tt> option given
521 <div class=
"paragraph"><p>By default, the notes shown are from the notes refs listed in the
522 <em>core.notesRef
</em> and
<em>notes.displayRef
</em> variables (or corresponding
523 environment overrides). See
<a href=
"git-config.html">git-config(
1)
</a> for more details.
</p></div>
524 <div class=
"paragraph"><p>With an optional
<em><ref
></em> argument, show this notes ref instead of the
525 default notes ref(s). The ref is taken to be in
<tt>refs/notes/
</tt> if it
526 is not qualified.
</p></div>
527 <div class=
"paragraph"><p>Multiple --notes options can be combined to control which notes are
528 being displayed. Examples:
"--notes=foo" will show only notes from
529 "refs/notes/foo";
"--notes=foo --notes" will show both notes from
530 "refs/notes/foo" and from the default notes ref(s).
</p></div>
537 Do not show notes. This negates the above
<tt>--notes
</tt> option, by
538 resetting the list of notes refs from which notes are shown.
539 Options are parsed in the order given on the command line, so e.g.
540 "--notes --notes=foo --no-notes --notes=bar" will only show notes
541 from
"refs/notes/bar".
545 --show-notes[=
<ref

548 --[no-]standard-notes

956 newline) appended, rather than a separator placed between entries.
957 This means that the final entry of a single-line format will be properly
958 terminated with a new line, just as the
"oneline" format does.

1039 The pathnames recorded in the index and in the tree objects

1041 What readdir(

1042 with the data git keeps track of, which in turn are expected
1043 to be what lstat(

1044 thing as pathname encoding translation.
1049 The contents of the blob objects are uninterpreted sequences
1050 of bytes. There is no encoding translation at the core

1062 in UTF-

1071 a warning if the commit log message given to it does not look
