我有一个命令,运行良好,如果我ssh到一台机器并运行它,但失败时,我试图运行它使用远程ssh命令,如:
ssh user@IP <command>
比较使用这两种方法的“env”的输出会得到不同的环境。当我手动登录到机器并运行env时,我得到了比运行时更多的环境变量:
ssh user@IP "env"
知道为什么吗?

我也有类似的问题,但最后我发现~/。bashrc是我所需要的。
但是,在Ubuntu中,我必须注释停止处理~/的行。bashrc: (
#If not running interactively, don't do anything
[ -z "$PS1" ] && return

在运行命令之前如何获取概要文件?
SSH user@host "source /etc/profile;/道路/ script.sh”
您可能会发现最好将其更改为~/。bash_profile、~ /。Bashrc之类的。
(如这里(linuxquestions.org))
有不同类型的外壳。SSH命令执行shell是非交互式shell,而普通的shell是登录shell或交互式shell。描述如下,来自man bash:
A login shell is one whose first character of argument zero is a -, or one started with the --login option. An interactive shell is one started without non-option arguments and without the -c option whose standard input and error are both connected to terminals (as determined by isatty(3)), or one started with the -i option. PS1 is set and $- includes i if bash is interactive, allowing a shell script or a startup file to test this state. The following paragraphs describe how bash executes its startup files. If any of the files exist but cannot be read, bash reports an error. Tildes are expanded in file names as described below under Tilde Expansion in the EXPANSION section. When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behav ior. When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists. When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc. When bash is started non-interactively, to run a shell script, for example, it looks for the variable BASH_ENV in the environment, expands its value if it appears there, and uses the expanded value as the name of a file to read and execute. Bash behaves as if the following command were executed: if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi but the value of the PATH variable is not used to search for the file name.
执行remote ssh命令时Shell环境未加载。您可以编辑ssh环境文件:
vi ~/.ssh/environment
其格式为:
VAR1=VALUE1
VAR2=VALUE2
此外,检查sshd配置的PermitUserEnvironment=yes选项。

只需要导出在~/.bashrc中检查非交互式shell时需要的环境变量。
