  19
  20 'rev-list' is an essential Git command, since it
  21 provides the ability to build and traverse commit ancestry graphs. For
  22 this reason, it has a lot of different options that enable it to be
  23 used by commands as different as 'git bisect' and
  24 'git repack'.

  34 EXAMPLES
  35 --------
  36
  37 * Print the list of commits reachable from the current branch.
  38 +
  39 ----------
  40 git rev-list HEAD
  41 ----------
  42
  43 * Print the list of commits on this branch, but not present in the
  44   upstream branch.
  45 +
  46 ----------
  47 git rev-list @{upstream}..HEAD
  48 ----------
  49
  50 * Format commits with their author and commit message (see also the
  51   porcelain linkgit:git-log[1]).
  52 +
  53 ----------
  54 git rev-list --format=medium HEAD
  55 ----------
  56
  57 * Format commits along with their diffs (see also the porcelain
  58   linkgit:git-log[1], which can do this in a single process).
  59 +
  60 ----------
  61 git rev-list HEAD |
  62 git diff-tree --stdin --format=medium -p
  63 ----------
  64
  65 * Print the list of commits on the current branch that touched any
  66   file in the `Documentation` directory.
  67 +
  68 ----------
  69 git rev-list HEAD -- Documentation/
  70 ----------
  71
  72 * Print the list of commits authored by you in the past year, on
  73   any branch, tag, or other ref.
  74 +
  75 ----------
  76 git rev-list --author=you@example.com --since=1.year.ago --all
  77 ----------
  78
  79 * Print the list of objects reachable from the current branch (i.e., all
  80   commits and the blobs and trees they contain).
  81 +
  82 ----------
  83 git rev-list --objects HEAD
  84 ----------
  85
  86 * Compare the disk size of all reachable objects, versus those
  87   reachable from reflogs, versus the total packed size. This can tell
  88   you whether running `git repack -ad` might reduce the repository size
  89   (by dropping unreachable objects), and whether expiring reflogs might
  90   help.
  91 +
  92 ----------
  93 # reachable objects
  94 git rev-list --disk-usage --objects --all
  95 # plus reflogs
  96 git rev-list --disk-usage --objects --all --reflog
  97 # total disk size used
  98 du -c .git/objects/pack/*.pack .git/objects/??/*
  99 # alternative to du: add up "size" and "size-pack" fields
 100 git count-objects -v
 101 ----------
 102
 103 * Report the disk size of each branch, not including objects used by the
 104   current branch. This can find outliers that are contributing to a
 105   bloated repository size (e.g., because somebody accidentally committed
 106   large build artifacts).
 107 +
 108 ----------
 109 git for-each-ref --format='%(refname)' |
 110 while read branch
 111 do
 112         size=$(git rev-list --disk-usage --objects HEAD..$branch)
 113         echo "$size $branch"
 114 done |
 115 sort -n
 116 ----------
 117
 118 * Compare the on-disk size of branches in one group of refs, excluding
 119   another. If you co-mingle objects from multiple remotes in a single
 120   repository, this can show which remotes are contributing to the
 121   repository size (taking the size of `origin` as a baseline).
 122 +
 123 ----------
 124 git rev-list --disk-usage --objects --remotes=$suspect --not --remotes=origin
