strace -f -F -o /adx_engine.txt /home/huyunzhi/adx-engine/adx_engine 这里 -f -F选项告诉strace同时跟踪fork和vfork出来的进程，-o选项把所有strace输出写到/dcop-strace.txt里 面，dcopserver是要启动和调试的程序

git branch -r -r 远程分支 -a 所有本地和远程分支

从特定tag开始项目 $ git clone git://git.kernel.org/pub/scm/.../linux-2.6 my2.6 $ cd my2.6 $ git branch my2.6.14 v2.6.14 (1) $ git switch my2.6.14

1. This step and the next one could be combined into a single step with "checkout -b my2.6.14 v2.6.14".

删除不需要的分支 $ git clone git://git.kernel.org/.../git.git my.git $ cd my.git $ git branch -d -r origin/todo origin/html origin/man (1) $ git branch -D test (2)

1. Delete the remote-tracking branches "todo", "html" and "man". The next fetch or pull will create them again unless you configure them not to.See git-fetch(1).
2. Delete the "test" branch even if the "master" branch (or whichever branch is currently checked out) does not have all commits from the test branch.

合并Merge 冲突 $git fetch origin $git checkout -b feature-dsplog origin/feature-dsplog

$git fetch origin $git checkout origin/master

合并merge操作 $git merge --no-ff feature-dsplog 查看冲突 $git status On branch master Your branch is up to date with 'origin/master'.

You have unmerged paths. (fix conflicts and run "git commit") (use "git merge --abort" to abort the merge)
