在bash脚本源文件。 [英] Source files in a bash script.
问题描述
我用彼此相邻ROS的两个版本。使用一个我要采购一些环境变量的特定版本。我想创建一个脚本,做到这一点。
但是,如果我创建一个脚本像下面的变量都没有设置,他们很可能在子shell设置。我如何可以将文件源到主终端的壳呢?
source.sh
源/opt/ros/fuerte/setup.bash;
源〜/ fuerte_workspace / setup.bash;
执行Shell脚本使用。 ./(点空间点斜杠)
在使用点空间点斜杠
,如下图所示,将执行在当前shell脚本但不分叉一个子壳执行shell脚本。
$。 ./setup.bash
在换句话说,这执行在当前shell中的 setup.bash
指定的命令,和prepares环境适合你。
I am using two versions of ROS next to each other. To use one I have to source some enviroment variables for the specific version. I would like to create a script that does this. But if I create a script like below the variables are not set, they are probably set in a subshell. How can I source the files to the main terminal shell?
source.sh
source /opt/ros/fuerte/setup.bash;
source ~/fuerte_workspace/setup.bash;
Execute Shell Script Using . ./ (dot space dot slash)
While executing the shell script using "dot space dot slash"
, as shown below, it will execute the script in the current shell without forking a sub shell.
$ . ./setup.bash
In other words, this executes the commands specified in the setup.bash
in the current shell, and prepares the environment for you.
