git rebase 到更新的master

宋鹏 — Fri, 02 Apr 2021 06:33:00 GMT

1. Assume the following history exists and the current branch is "topic":

A---B---C topic

D---E---F---G master

From this point, the result of either of the following commands:

git rebase master

git rebase master topic

would be:

A'--B'--C' topic

D---E---F---G master

2. git rebase �q�程中：
在修改完需要merge的文件后�Q�用git add和git status来确认rebase状态，然后再git rebase --continue

git tag and git describe a specified path/commits/tags

宋鹏 — Wed, 13 Jan 2021 02:40:00 GMT

1. Create a tag with patterned name

git tag "tagname_v1.02"

(one tag is pointed to a specified commit)

2. get tag describe to use in software version name

git describe --tags --long --dirty=* --match "tagname*"

> tagname_v1.02-0-g59584af

3. push tag name to remote repo

git push origin --tags

unix/windows回�R问题(\r\n or \n) or shell脚本执行错误 $'\r':command not found

宋鹏 — Fri, 25 Oct 2019 02:41:00 GMT

unix/windows回�R问题

shell脚本执行错误 $'\r':command not found
存现�q�种错误是因�?�~�写�?nbsp; shell脚本是在win下编写的�Q�每行结��是\r\n 的Unix �l�果行是\n
所以在Linux下运行脚�?会�Q务\r 是一个字�W�，所以运行错误，需要把文�g转换下�?/div>

1.单个文�g转换�Q?/div>

�q�行脚本

dos2unix 脚本�?/div>

2.整个目录中的文�g做dos2unix操作:

$ find . -type f -exec dos2unix {} \;

其中具体命��o的解释如下：

find .

= find files in the current directory

-type f

= of type f

-exec dos2unix {} \;

= and execute dos2unix on each file found

If you don't already have a .vimrc file in your home directory, create one using this:
vim ~/.vimrc
Add this line to the top of the file:
set nocompatible
Save the file and this should fix the problem for you. :)

5.10.1的关于glibc的renameat的bug�Q�被官方�?.11的branch里修复如下：
commit 25feee4e061b99edab79503d81f5bd045c6c8e3d
Author: Thiago Macieira
Date: Tue Aug 7 09:38:42 2018 -0700
Fix qmake build with glibc 2.28

We haven't yet run the configure checks to see if statx and renameat2
are present in glibc, so this fails when we redefine the structures and
functions.

linux/stat.h:56:8: error: redefinition of 'struct statx_timestamp'
bits/statx.h:25:8: note: previous definition of 'struct statx_timestamp'
qfilesystemengine_unix.cpp:110:12: error: 'int renameat2(int, const char*, int, const char*, unsigned int)' was declared 'extern' and later 'static' [-fpermissive]

宋鹏 — Mon, 04 Mar 2019 08:26:00 GMT

add:
git add *

undo add:
You can undo git add before commit with

git reset

which will remove it from the current index (the "about to be committed" list) without changing anything else.

You can use

git reset

add brach:
git branch rikSkinLoader

view branch:
git branch -a

switch branch:
git checkout BranchName

delete branch:
git branch -d

push branch:
git push origin branchname

pull:
git pull origin �Q?lt;local_branch>
git pull origin master:master

查看�q�端变更/后箋操作�Q?br />git remote update

First use git remote update, to bring your remote refs up to date. Then you can do one of several things, such as:

git status -uno
git status -uno will tell you whether the branch you are tracking is ahead, behind or has diverged. If it says nothing, the local and remote are the same.
git show-branch *master
git show-branch *master will show you the commits in all of the branches whose names end in 'master' (eg master and origin/master).
