1git-for-each-ref(1) 2=================== 3 4NAME 5---- 6git-for-each-ref - Output information on each ref 7 8SYNOPSIS 9-------- 10[verse] 11'git for-each-ref' [--count=<count>] [--shell|--perl|--python|--tcl] 12 [(--sort=<key>)...] [--format=<format>] [<pattern>...] 13 14DESCRIPTION 15----------- 16 17Iterate over all refs that match `<pattern>` and show them 18according to the given `<format>`, after sorting them according 19to the given set of `<key>`. If `<count>` is given, stop after 20showing that many refs. The interpolated values in `<format>` 21can optionally be quoted as string literals in the specified 22host language allowing their direct evaluation in that language. 23 24OPTIONS 25------- 26<count>:: 27 By default the command shows all refs that match 28 `<pattern>`. This option makes it stop after showing 29 that many refs. 30 31<key>:: 32 A field name to sort on. Prefix `-` to sort in 33 descending order of the value. When unspecified, 34 `refname` is used. You may use the --sort=<key> option 35 multiple times, in which case the last key becomes the primary 36 key. 37 38<format>:: 39 A string that interpolates `%(fieldname)` from the 40 object pointed at by a ref being shown. If `fieldname` 41 is prefixed with an asterisk (`*`) and the ref points 42 at a tag object, the value for the field in the object 43 tag refers is used. When unspecified, defaults to 44 `%(objectname) SPC %(objecttype) TAB %(refname)`. 45 It also interpolates `%%` to `%`, and `%xx` where `xx` 46 are hex digits interpolates to character with hex code 47 `xx`; for example `%00` interpolates to `\0` (NUL), 48 `%09` to `\t` (TAB) and `%0a` to `\n` (LF). 49 50<pattern>...:: 51 If one or more patterns are given, only refs are shown that 52 match against at least one pattern, either using fnmatch(3) or 53 literally, in the latter case matching completely or from the 54 beginning up to a slash. 55 56--shell:: 57--perl:: 58--python:: 59--tcl:: 60 If given, strings that substitute `%(fieldname)` 61 placeholders are quoted as string literals suitable for 62 the specified host language. This is meant to produce 63 a scriptlet that can directly be `eval`ed. 64 65 66FIELD NAMES 67----------- 68 69Various values from structured fields in referenced objects can 70be used to interpolate into the resulting output, or as sort 71keys. 72 73For all objects, the following names can be used: 74 75refname:: 76 The name of the ref (the part after $GIT_DIR/). 77 For a non-ambiguous short name of the ref append `:short`. 78 The option core.warnAmbiguousRefs is used to select the strict 79 abbreviation mode. 80 81objecttype:: 82 The type of the object (`blob`, `tree`, `commit`, `tag`). 83 84objectsize:: 85 The size of the object (the same as 'git cat-file -s' reports). 86 87objectname:: 88 The object name (aka SHA-1). 89 For a non-ambiguous abbreviation of the object name append `:short`. 90 91upstream:: 92 The name of a local ref which can be considered ``upstream'' 93 from the displayed ref. Respects `:short` in the same way as 94 `refname` above. Additionally respects `:track` to show 95 "[ahead N, behind M]" and `:trackshort` to show the terse 96 version: ">" (ahead), "<" (behind), "<>" (ahead and behind), 97 or "=" (in sync). Has no effect if the ref does not have 98 tracking information associated with it. 99 100push:: 101 The name of a local ref which represents the `@{push}` location 102 for the displayed ref. Respects `:short`, `:track`, and 103 `:trackshort` options as `upstream` does. Produces an empty 104 string if no `@{push}` ref is configured. 105 106HEAD:: 107 '*' if HEAD matches current ref (the checked out branch), ' ' 108 otherwise. 109 110color:: 111 Change output color. Followed by `:<colorname>`, where names 112 are described in `color.branch.*`. 113 114In addition to the above, for commit and tag objects, the header 115field names (`tree`, `parent`, `object`, `type`, and `tag`) can 116be used to specify the value in the header field. 117 118Fields that have name-email-date tuple as its value (`author`, 119`committer`, and `tagger`) can be suffixed with `name`, `email`, 120and `date` to extract the named component. 121 122The complete message in a commit and tag object is `contents`. 123Its first line is `contents:subject`, where subject is the concatenation 124of all lines of the commit message up to the first blank line. The next 125line is 'contents:body', where body is all of the lines after the first 126blank line. Finally, the optional GPG signature is `contents:signature`. 127 128For sorting purposes, fields with numeric values sort in numeric 129order (`objectsize`, `authordate`, `committerdate`, `taggerdate`). 130All other fields are used to sort in their byte-value order. 131 132In any case, a field name that refers to a field inapplicable to 133the object referred by the ref does not cause an error. It 134returns an empty string instead. 135 136As a special case for the date-type fields, you may specify a format for 137the date by adding `:` followed by date format name (see the 138values the `--date` option to linkgit::git-rev-list[1] takes). 139 140 141EXAMPLES 142-------- 143 144An example directly producing formatted text.
