如何将环境设置导入到我的Perl程序中? [英] How do I import environment settings into my Perl program?

问题描述

我有一个脚本，其内容只是在Linux中导出一个变量.

I have a script whose content simply exports a variable in linux.

export LD_LIBRARY_PATH=....

我想在我的Perl脚本中运行此脚本，因此无论谁运行我的Perl脚本，都将设置其LD_LIBRARY_PATH.我可以在Perl脚本的开头执行此操作吗?

I want to run this script in my Perl script so whoever is running my Perl script will have their LD_LIBRARY_PATH set. Can i just do this in the beginning of my Perl script:

#!/usr/bin/perl -w

system(". /myfolder1/myfolder2/myScript.sh");

推荐答案

#!/bin/sh
. /myfolder1/myfolder2/myScript.sh
exec perl -wxS "$0" "$@"
#!/usr/bin/perl -w
# .. the rest of your script as normal

运行此命令时，它将首先由/bin/sh执行，它可以将myScript.sh加载到本地环境中. sh然后是exec s Perl，然后告诉它从下一行继续.

When you run this, it will first be executed by /bin/sh, which is capable of loading myScript.sh into the local environment. sh then execs Perl, which is told to continue from the following line.
