Could you please tell me where can I add export PATH=/home/usrname/epd/bin:$PATH to or is should be added in another file?

推荐答案

你可以这样做:定义一个 EPD_HOME 变量并将其附加到 PATH

You can do it like this : Define a EPD_HOME var and append it to PATH

EPD_HOME=/home/usrname/epd/bin PATH=$PATH:$EPD_HOME:$HOME/bin export PATH

请注意，$EPD_HOME 变量位于 PATH 变量中，一旦您在计算机上打开与用户的连接，就会加载该变量.

Notice that the $EPD_HOME variable is in the PATH variable and is now loaded once you open a connection to your user on the machine.
