源/别名在Mac .bashrc中不是永久的

Question

I have a .sources symlink pointing to a directory with files I wish to source when Terminal is opened.

In my .bashrc file, which is sourced from ~/.bash_profile , I have the following code

sourcesDir=$HOME/.sources
ls -B $sourcesDir | while read filename; do
  echo "source $sourcesDir/$filename"
  source $sourcesDir/$filename
done

When I start Terminal, I get the following output

source /Users/merlinpatterson/.sources/bash_aliases
source /Users/merlinpatterson/.sources/git_completion.bash
source /Users/merlinpatterson/.sources/git_prompt.sh
source /Users/merlinpatterson/.sources/meteor.sh

However, when I run alias , none of the aliases show up. Any variables exported are blank. And __git_ps1 is not found.

If I run the above commands after starting the Terminal, everything works, so the files themselves are fine.

Why are the results of source not staying around in the Terminal?

The while loop runs in a subshell, not your current shell. Use instead

for filename in "$sourcesDir"/*; do
    source "$filename"
done
