如何在linux或unix上找到用户的主目录？
问题描述：
如何从Grails中找到任意用户的主目录？在Linux上通常是/ home / user。但是，在某些操作系统上，例如OpenSolaris，路径为/ export / home / user。
How do I find the home directory of an arbitrary user from within Grails? On Linux it's often /home/user. However, on some OS's, like OpenSolaris for example, the path is /export/home/user.

您可能希望使用shell执行 echo-username 系统（因此使用 Runtime.exec（）来运行 {/ bin / sh，-c，echo〜username} ）。
For UNIX-Like systems you might want to execute "echo ~username" using the shell (so use Runtime.exec() to run {"/bin/sh", "-c", "echo ~username"}).
