Adding a directory to PATH in Ubuntu
提问by Tofayel Ahmed
I am a new user of Linux, just switched from Windows. I installed ActiveTcl-8.5 in /opt/ActiveTcl-8.5/, now I want to add its bindirectory to the UNIX path.
我是 Linux 的新用户，刚从 Windows 切换过来。我在 中安装了 ActiveTcl-8.5 /opt/ActiveTcl-8.5/，现在我想将其bin目录添加到 UNIX 路径中。
I have read a number of articles from the net and got confused about which file to modify. My /home/tofayeldirectory contains .bashrc, .bash_logout, .bash_history, and .profile; but not .bash_loginand .bash_profile.
我从网上阅读了许多文章，并对要修改的文件感到困惑。我的/home/tofayel目录包含.bashrc, .bash_logout, .bash_history, 和.profile; 但不是.bash_login和.bash_profile。
Where do I add the extra lines to add /opt/ActiveTcl-8.5/binto PATH?
我在哪里添加要添加/opt/ActiveTcl-8.5/bin到 PATH的额外行？

The file .bashrcis read when you start an interactive shell. This is the file that you should update. E.g:
.bashrc当您启动交互式 shell 时会读取该文件。这是您应该更新的文件。例如：
export PATH=$PATH:/opt/ActiveTcl-8.5/bin
Restart the shell for the changes to take effect or source it, i.e.:
重新启动外壳以使更改生效或获取它，即：
source .bashrc

you can set it in .bashrc
你可以在 .bashrc 中设置它
PATH=$PATH:/opt/ActiveTcl-8.5/bin;export PATH;

Actually I would advocate .profileif you need it to work from scripts, and in particular, scripts run by /bin/sh instead of Bash. If this is just for your own private interactive use, .bashrcis fine, though.
实际上，我建议.profile您是否需要它从脚本中工作，特别是由 /bin/sh 而不是 Bash 运行的脚本。不过，如果这只是为了您自己的私人互动使用，那.bashrc很好。
