1git-apply(1) 2============ 3 4NAME 5---- 6git-apply - Apply patch on a git index file and a work tree 7 8 9SYNOPSIS 10-------- 11[verse] 12'git-apply' [--stat] [--numstat] [--summary] [--check] [--index] [--apply] 13 [--no-add] [--index-info] [--allow-binary-replacement] [-z] [-pNUM] 14 [-CNUM] [--whitespace=<nowarn|warn|error|error-all|strip>] 15 [<patch>...] 16 17DESCRIPTION 18----------- 19Reads supplied diff output and applies it on a git index file 20and a work tree. 21 22OPTIONS 23------- 24<patch>...:: 25 The files to read patch from. '-' can be used to read 26 from the standard input. 27 28--stat:: 29 Instead of applying the patch, output diffstat for the 30 input. Turns off "apply". 31 32--numstat:: 33 Similar to \--stat, but shows number of added and 34 deleted lines in decimal notation and pathname without 35 abbreviation, to make it more machine friendly. Turns 36 off "apply". 37 38--summary:: 39 Instead of applying the patch, output a condensed 40 summary of information obtained from git diff extended 41 headers, such as creations, renames and mode changes. 42 Turns off "apply". 43 44--check:: 45 Instead of applying the patch, see if the patch is 46 applicable to the current work tree and/or the index 47 file and detects errors. Turns off "apply". 48 49--index:: 50 When --check is in effect, or when applying the patch 51 (which is the default when none of the options that 52 disables it is in effect), make sure the patch is 53 applicable to what the current index file records. If 54 the file to be patched in the work tree is not 55 up-to-date, it is flagged as an error. This flag also 56 causes the index file to be updated. 57 58--index-info:: 59 Newer git-diff output has embedded 'index information' 60 for each blob to help identify the original version that 61 the patch applies to. When this flag is given, and if 62 the original version of the blob is available locally, 63 outputs information about them to the standard output. 64 65-z:: 66 When showing the index information, do not munge paths, 67 but use NUL terminated machine readable format. Without 68 this flag, the pathnames output will have TAB, LF, and 69 backslash characters replaced with `\t`, `\n`, and `\\`, 70 respectively. 71 72-p<n>:: 73 Remove <n> leading slashes from traditional diff paths. The 74 default is 1. 75 76-C<n>:: 77 Ensure at least <n> lines of surrounding context match before 78 and after each change. When fewer lines of surrounding 79 context exist they all must match. By default no context is 80 ever ignored. 81 82--apply:: 83 If you use any of the options marked ``Turns off 84 "apply"'' above, git-apply reads and outputs the 85 information you asked without actually applying the 86 patch. Give this flag after those flags to also apply 87 the patch. 88 89--no-add:: 90 When applying a patch, ignore additions made by the 91 patch. This can be used to extract common part between 92 two files by first running `diff` on them and applying 93 the result with this option, which would apply the 94 deletion part but not addition part. 95 96--allow-binary-replacement:: 97 When applying a patch, which is a git-enhanced patch 98 that was prepared to record the pre- and post-image object 99 name in full, and the path being patched exactly matches 100 the object the patch applies to (i.e. "index" line's 101 pre-image object name is what is in the working tree), 102 and the post-image object is available in the object 103 database, use the post-image object as the patch 104 result. This allows binary files to be patched in a 105 very limited way. 106 107--whitespace=<option>:: 108 When applying a patch, detect a new or modified line 109 that ends with trailing whitespaces (this includes a 110 line that solely consists of whitespaces). By default, 111 the command outputs warning messages and applies the 112 patch. 113 When `git-apply` is used for statistics and not applying a 114 patch, it defaults to `nowarn`. 115 You can use different `<option>` to control this 116 behavior: 117+ 118* `nowarn` turns off the trailing whitespace warning. 119* `warn` outputs warnings for a few such errors, but applies the 120 patch (default). 121* `error` outputs warnings for a few such errors, and refuses 122 to apply the patch. 123* `error-all` is similar to `error` but shows all errors. 124* `strip` outputs warnings for a few such errors, strips out the 125 trailing whitespaces and applies the patch. 126 127 128Configuration 129------------- 130 131apply.whitespace:: 132 When no `--whitespace` flag is given from the command 133 line, this configuration item is used as the default. 134 135 136Author 137------ 138Written by Linus Torvalds <torvalds@osdl.org> 139 140Documentation 141-------------- 142Documentation by Junio C Hamano 143 144GIT 145--- 146Part of the gitlink:git[7] suite 147
