Bash 每次打开 Ubuntu 终端时都没有这样的文件或目录

Question

I am new to Ubuntu and Linux terminal, for other purposes I have executed some commands related to adding environment variables(I guess) as follows:

echo "source ~[some path]/setup.bash" >> ~/.bashrc

and

source ~/.bashrc

However, during my process of figuring out the right path, I executed the above commands with the wrong path several times before I got it right. Now I think my desired environment variable have been successfully added but those "bad" path have been added and every time I open the terminal I got all those 'bash: xxxx No such file or directory' warning: screen shot It's not a serious bug but I wonder if there is a way I can get rid of them? Many thanks!

You've obscured the paths themselves, but I managed to work out that the last file you're trying to load is in the path ~Desktop , whereas I think you meant ~/Desktop . In your .profile or .bashrc files, I'd rather use the env variables, though, and use $HOME for paths under my home directory.

Lastly, using source is absolutely fine (and POSIX compliant), but seeing as your file is called .bashrc , it's safe to assume that you're only targetting bash. To save some typing, bash has source aliased to . (dot). What I'd write in my bashrc file, then, would be:

. "${HOME}/Desktop/path/to/script.sh"

This does mean the append echo command you have is probably best changed to use single quotes:

echo '. "${HOME}/some/path/setup.sh"'

Just keep in mind: having multiple slashes where you only need one (eg /home/foo///bar////path///file.sh ) is safer/better than omitting a required slash (which is what was causing your problem).
