Adding a path to the .bashrc file?
提问by user1825241
At the moment I am trying to add a path for ns-2 to my .bashrc file, I have installed the ns-allinone-2.34 but the command ns gives the result: command not found when entered into the shell.
目前，我正在尝试将 ns-2 的路径添加到我的 .bashrc 文件中，我已经安装了 ns-allinone-2.34，但是命令 ns 给出了结果：进入 shell 时找不到命令。
Here is what my .bashrc file currently looks like, I edited it using gedit:
这是我的 .bashrc 文件当前的样子，我使用 gedit 对其进行了编辑：
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific aliases and functions
export PATH=/home/michael/ns-allinone-2.34/bin/ns:/home/michael/ns-allinone-2.34/bin/nam:$PATH
Can someone please explain why this isn't working or what a possible solution may be? I am using fedora 17.
有人可以解释为什么这不起作用或可能的解决方案是什么？我正在使用 Fedora 17。

The PATHshould contain the directoryfor the binaries, not the binaries themselves.
本PATH应包含目录的二进制文件，而不是二进制文件本身。
For example, in the above:
例如，在上面：
export PATH=/home/michael/ns-allinone-2.34/bin/ns:..
should actually be:
实际上应该是：
export PATH=/home/michael/ns-allinone-2.34/bin:...

Also if you export path like this, you want to keep old PATH as well, therefore include it as well.
此外，如果您像这样导出路径，您也希望保留旧的 PATH，因此也包括它。
export PATH=$PATH:/home/michael/ns-allinone-2.34/bin/
