-SSH client (ssh) is a Linux/Unix command for logging into a remote server and for executing shell commands on a remote system. It is designed to provide secure encrypted communications between two untrusted machines over an insecure network such as the Internet.

-I have [set up a bash alias named file_repl][1] . It works entirely when I log in using ssh command. However, my bash aliases are not running over ssh, for example:How do I run bash shell aliases when I use ssh command?SSH client (ssh) is a Linux/Unix command for logging into a remote server and for executing shell commands on a remote system.

-## Understanding bash shall and command types
-
-The [bash shell understands][4] the following types of commands:
-
-  1. Aliases such as ll
-  2. Keywords such as if
-  3. Functions (user defined functions such as genpasswd)
-  4. Built in such as pwd
-  5. Files such as /bin/date
-
-
-
-The [type command][5] or [command command][6] can be used to find out a command type:
-```
-$ type -a date
-date is /bin/date
-$ type -a free
-free is /usr/bin/free
-$ command -V pwd
-pwd is a shell builtin
-$ type -a file_repl
-is aliased to `sudo -i /shared/takes/master.replication'
-```
-Both date and free are an external commands and file_repl is aliased to sudo -i /shared/takes/master.replication. One can not simply execute aliased command such as file_repl:
-
-```
-$ ssh user@remote file_repl
-```
-
-## Bash aliases not running or working over ssh client on Unix based system
-
-To solve this problem run ssh command as follows:
-```
-$ ssh -t [[email protected]][3] /bin/bash -ic 'your-alias-here'
-$ ssh -t [[email protected]][3] /bin/bash -ic 'file_repl'
-```
-Where ssh command options:
-
-  1.  **-t** :[ Force pseudo-terminal allocation. This can be used to execute arbitrary][7] screen-based programs on a remote machine, which can be very useful. With the -t option you will get an error that read as " bash: cannot set terminal process group (-1): Inappropriate ioctl for device. bash: no job control in this shell. "
-
-
-
-Where bash shell options:
-
-  1.  **-i** : Make the shell is interactive so that it can run bash aliases
-  2.  **-c** : Commands are read from the first non-option argument command_string. If there are arguments after the command_string, they are assigned to the positional parameters, starting with $0.
-
-In short run the following command to run a bash aliases called ll:
-`$ ssh -t [[email protected]][3] -ic 'll'`
-Sample session:
-[![Running bash aliases over ssh based session when using Unix or Linux ssh cli][8]][8]
-Here is my sample shell script:
-
-```
-#!/bin/bash
-I="tags.deleted.410"
-O="/tmp/https.www.cyberciti.biz.410.url.conf"
-box="vivek@server1.cyberciti.biz"
-[ ! -f "$I" ] && { echo "$I file not found."; exit 10; }
->$O
-cat "$I" | sort | uniq | while read -r u
-do
-	uu="${u##https://www.cyberciti.biz}"
-	echo "~^$uu 1;" >>"${O}"
-done
-echo "Config file created at ${O} and now updating remote nginx config file"
-scp "${O}" ${box}:/tmp/
-ssh ${box} /usr/bin/lxc file push /tmp/https.www.cyberciti.biz.410.url.conf nginx-container/etc/nginx/
-ssh -t ${box} /bin/bash -ic 'push_config_job'

+通过 ssh 会话执行 bash 别名
+======
+
+我在远程主机上[上设置过一个叫做 file_repl 的 bash 别名 ][1] . 当我使用 ssh 命令登陆远程主机后，可以很正常的使用这个别名。然而这个 bash 别名却无法通过 ssh 来运行，像这样：
+```
+$ ssh vivek@server1.cyberciti.biz file_repl
+bash：file_repl：command not found
+```
+
+我要怎样做才能通过 ssh 命令运行 bash 别名呢？
+
+SSH 客户端 (ssh) 是一个登陆远程服务器并在远程系统上执行 shell 命令的 Linux/Unix 命令。它被设计用来在两个非信任的机器上通过不安全的网络(比如互联网)提供安全的加密通讯。
+
+## 如何用 ssh 客户端执行命令
+
+通过 ssh 运行 free 命令或 [date 命令 ][2] 可以这样做：
+`$ ssh vivek@server1.cyberciti.biz date`
+结果为：
+```
+Tue Dec 26 09：02：50 UTC 2017
+```
+
+或者
+`$ ssh vivek@server1.cyberciti.biz free -h`
+结果为：
+```
+ 
+ total used free shared buff/cache available
+Mem：2.0G 428M 138M 145M 1.4G 1.1G
+Swap：0B 0B 0B
+```
+
+## 理解 bash shell 以及命令的类型
+
+[bash shell][4] 共有下面几类命令：
+
+  1。别名，比如 ll
+  2。关键字，比如 if
+  3。函数(用户自定义函数，比如 genpasswd)
+  4。内置命令，比如 pwd
+  5。外部文件，比如 /bin/date
+
+The [type 命令 ][5] 和 [command 命令 ][6] 可以用来查看命令类型：
+```
+$ type -a date
+date is /bin/date
+$ type -a free
+free is /usr/bin/free
+$ command -V pwd
+pwd is a shell builtin
+$ type -a file_repl
+is aliased to `sudo -i /shared/takes/master.replication'
+```
+date 和 free 都是外部命令而 file_repl 是 `sudo -i /shared/takes/master.replication` 的别名。你不能直接执行像 file_repl 这样的别名：
+
+```
+$ ssh user@remote file_repl
+```
+
+## 在 Unix 系统上无法直接通过 ssh 客户端执行 bash 别名
+
+要解决这个问题可以用下面方法运行 ssh 命令：
+```
+$ ssh -t user@remote /bin/bash -ic 'your-alias-here'
+$ ssh -t user@remote /bin/bash -ic 'file_repl'
+```
+ssh 命令选项：
+
+  1。**-t**：[强制分配伪终端。可以用来在远程机器上执行任意的 ][7] 基于屏幕的程序，有时这非常有用。当使用 `-t` 时你可能会收到一个类似" bash：cannot set terminal process group (-1)：Inappropriate ioctl for device。bash：no job control in this shell ." 的错误。
+
+
+
+bash shell 的选项：
+
+  1。**-i**：运行交互 shell，这样 shell 才能运行 bash 别名
+  2。**-c**：要执行的命令取之于第一个非选项参数的命令字符串。若在命令字符串后面还有其他参数，这些参会会作为位置参数传递给命令，参数从 $0 开始。
+
+总之，要运行一个名叫 `ll` 的 bash 别名，可以运行下面命令：
+`$ ssh -t [[email protected]][3] -ic 'll'`
+结果为：
+[![Running bash aliases over ssh based session when using Unix or Linux ssh cli][8]][8]
+
+下面是我的一个 shell 脚本的例子：
+
+```
+#！/bin/bash
+I="tags.deleted.410"
+O="/tmp/https.www.cyberciti.biz.410.url.conf"
+box="vivek@server1.cyberciti.biz"
+[！-f "$I" ] && { echo "$I file not found。"; exit 10; }
+>$O
+cat "$I" | sort | uniq | while read -r u
+do
+	uu="${u##https：//www.cyberciti.biz}"
+	echo "~^$uu 1;" >>"${O}"
+done
+echo "Config file created at ${O} and now updating remote nginx config file"
+scp "${O}" ${box}：/tmp/
+ssh ${box} /usr/bin/lxc file push /tmp/https.www.cyberciti.biz.410.url.conf nginx-container/etc/nginx/
+ssh -t ${box} /bin/bash -ic 'push_config_job'
+```
+
+## 相关资料
+
+更多信息请输入下面命令查看 [OpenSSH client][9] 和 [bash 的 man 帮助 ][10]：
+```
+$ man ssh
+$ man bash
+$ help type
+$ help command
+```
