ln -s的路径

河边星星

如我的一个在a目录下名为b软件:
/usr/local/a/b
./b是可以运行的

我将其
ln -s /usr/local/a/b /home/peter/Desktop/b
此时为什么不可以运行

当然我清楚只要将其
export /usr/local/aPATH
在任何路径下都可运行

可是软链接如何？？？？

问题来源于：直接解开就可以用./软件名来运行的软件

"此时为什么不可以运行",此时你想怎么运行b软件?

biinn

ls -l /home/peter/Desktop/b
to make sure if it is linked to /usr/local/a/b properly. and also please make sure /home/peter/Desktop is in your $PATH.

Please note that /home/locale/a does not need to be in $PATH, since you want to run /home/peter/Desktop/b, which path does need to be in $PATH.

OK, forget about the soft link. Assuming you have a executable file in /home/peter/Desktop/, can you run it outside of /home/peter/Desktop/ if /home/peter/Desktop/ is not in $PATH. You cannot, right? It is the same for a soft link.

Got it?
