1git-reflog(1) 2============= 3 4NAME 5---- 6git-reflog - Manage reflog information 7 8 9SYNOPSIS 10-------- 11'git reflog' <subcommand> <options> 12 13DESCRIPTION 14----------- 15The command takes various subcommands, and different options 16depending on the subcommand: 17 18[verse] 19git reflog expire [--dry-run] [--stale-fix] [--verbose] 20 [--expire=<time>] [--expire-unreachable=<time>] [--all] <refs>... 21 22git reflog [show] [log-options] 23 24Reflog is a mechanism to record when the tip of branches are 25updated. This command is to manage the information recorded in it. 26 27The subcommand "expire" is used to prune older reflog entries. 28Entries older than `expire` time, or entries older than 29`expire-unreachable` time and are not reachable from the current 30tip, are removed from the reflog. This is typically not used 31directly by the end users -- instead, see gitlink:git-gc[1]. 32 33The subcommand "show" (which is also the default, in the absence of any 34subcommands) will take all the normal log options, and show the log of 35`HEAD`, which will cover all recent actions, including branch switches. 36It is basically an alias for 'git log -g --abbrev-commit 37--pretty=oneline', see gitlink:git-log[1]. 38 39 40OPTIONS 41------- 42 43--stale-fix:: 44 This revamps the logic -- the definition of "broken commit" 45 becomes: a commit that is not reachable from any of the refs and 46 there is a missing object among the commit, tree, or blob 47 objects reachable from it that is not reachable from any of the 48 refs. 49+ 50This computation involves traversing all the reachable objects, i.e. it 51has the same cost as 'git prune'. Fortunately, once this is run, we 52should not have to ever worry about missing objects, because the current 53prune and pack-objects know about reflogs and protect objects referred by 54them. 55 56--expire=<time>:: 57 Entries older than this time are pruned. Without the 58 option it is taken from configuration `gc.reflogExpire`, 59 which in turn defaults to 90 days. 60 61--expire-unreachable=<time>:: 62 Entries older than this time and are not reachable from 63 the current tip of the branch are pruned. Without the 64 option it is taken from configuration 65 `gc.reflogExpireUnreachable`, which in turn defaults to 66 30 days. 67 68--all:: 69 Instead of listing <refs> explicitly, prune all refs. 70 71--verbose:: 72 Print extra information on screen. 73 74Author 75------ 76Written by Junio C Hamano <junkio@cox.net> 77 78Documentation 79-------------- 80Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. 81 82GIT 83--- 84Part of the gitlink:git[7] suite
