- 1、ssh-copy-id：千万不要把私钥泄漏！只是把公钥（*.pub 文件）复制给远程服务器，公钥就是要对外公开的。
# 1、IP+默认端口 这里拷贝的是公钥，，如果是指定私钥ssh-copy-id 会自己寻找公钥。 devzkndeMacBook-Pro:.ssh devzkn$ ssh-copy-id -i ~/.ssh/id_rsa_Theos125 root@192.168.2.144 # 本质上是将id_rsa.pub拷贝一份保存为authorized_keys iPhone:~/.ssh root# cat /var/root/.ssh/authorized_keys # 2、指定端口 devzkndeMacBook-Pro:SQTaoke devzkn$ ssh-copy-id -i -p 2222 ~/.ssh/id_rsa_Theos125 root@localhost:2222 # 3、使用别名 devzkndeMacBook-Pro:bin devzkn$ ssh-copy-id -i ~/.ssh/id_rsa_Theos125 iphone150 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/devzkn/.ssh/id_rsa_Theos125.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys root@192.168.2.163's password: Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'iphone150'" and check to make sure that only the key(s) you wanted were added. #4、使用负责脚本 #!/bin/sh # devzkndeMacBook-Pro:mplink devzkn$ sship 192.168.2.183 postName="root@"$1 ssh-copy-id -i ~/.ssh/id_rsa_Theos125 $postName exit 0

apt-get autoclean 清理旧版本的软件缓存 apt-get clean 清理所有软件缓存 apt-get autoremove 删除系统不再使用的孤立软件 nautilus /boot 删除除了最新内核以外的其它文件 gedit /boot/grub/menu.lst 删除除最新内核以外的其它启动项（
排查网络问题的常用命令
- 修改 手机hosts– 错误的用法
#echo -e "换\n行" install.exec "echo '127.0.0.1 localhost 192.168.2.254 wssesschknknknknkdsat.fkdjdasssllllqusssasssnwwwwgwwwe.cn' > /etc/hosts"- 修改 手机hosts 正确的用法
#echo -e "换\n行" install.exec "echo -e '127.0.0.1 localhost \n 192.168.2.107 kn.kn.cn' > /etc/hosts"- ping 网络
iPhone:~ root# ping wecKNhat.fsshhhhasqKNuanKNgllkjdde.cn
- curl 请求接口
iPhone:~ root# curl "http://wKNeKNcKNhKNat.faKNqKNuaKNnKNge.cn/inKNdeKNx.php?m=TKKNL&c=trKNKNansKNKNKNKNNfoKNKKNrm"
apt-get
- update
apt-get update- install
apt-get install socat
git
在遇到git 冲突的时候，常常可以利用git status 来查看解决方案
- 还原本地的修改
git reset --hard
git clean -fdx
- 查看所有分支
devzkndeMacBook-Pro:electra devzkn$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/cydia
remotes/origin/master
- 取回远程特定的分支
devzkndeMacBook-Pro:electra devzkn$ git fetch origin cydia
From github.com:coolstar/electra
* branch cydia -> FETCH_HEAD
<!-- 总结： 取回远程的一个分支 cydia-->
devzkndeMacBook-Pro:electra devzkn$ git checkout -b cydia origin/cydia
Branch cydia set up to track remote branch cydia from origin.
Switched to a new branch 'cydia'
devzkndeMacBook-Pro:electra devzkn$ git fetch origin
- 新建并切换到该分支
<!-- 运行 git checkout 并加上 -b 参数： -->
devzkndeMacBook-Pro: devzkn$ git checkout -b develop
git push --set-upstream origin develop
这相当于执行下面这两条命令：
$ git branch iss53
$ git checkout iss53
- 1、 git log
devzkndeMacBook-Pro:SQTaoke devzkn$ git log --pretty=oneline 461b940921343dd4163ab8abf41efca474db4fd9 (HEAD -> master, origin/master) first commitdevzkndeMacBook-Pro:SQTaoke devzkn$ git log -p -2- 2、 git reset
devzkndeMacBook-Pro:SQTaoke devzkn$ git reset --hard 32f87f5e93501b24d42c7aba49106dd9bed0b943 HEAD is now at 32f87f5 处理非200
- 3、git remote remove origin
git remote remove origin取消本地目录下关联的远程库;常常用于copyxx项目的基础上，创建新项目的场景
- git 常用合并命令
#切换回master分支 git checkout master # merge --no-ff参数，表示禁用Fast forward;可以保存你之前的分支历史。能够更好的查看merge历史，以及branch 状态. #保证版本提交、分支结构清晰 git merge --no-ff develop #push git push
- git ls-remote 查看远程仓库的
tag里程碑和分支branch一样也是以引用的形式存在的，保存在.git/refs/路径下

}
ios 中利用NSTask 执行shell脚本
//执行shell脚本
NSString *doShellCmd(NSString *cmd)
{
NSTask *task;
task = [[NSTask alloc ]init];//通过NSTask，您的程序可以分出 一个子进程来执行其它工作或进行进度监控。
[task setLaunchPath:@"/bin/bash"];
NSArray *arguments = [NSArray arrayWithObjects:@"-c",cmd, nil];
[task setArguments:arguments];
NSPipe *pipe = [NSPipe pipe];//NSPipe代表一个BSD管道，即一种进程间的单向通讯通道。 线程和子任务
[task setStandardOutput:pipe];
NSFileHandle *file = [pipe fileHandleForReading];
[task launch];
NSData *data = [file readDataToEndOfFile];
NSString *string = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
return string;
