source all files in a directory from .bash_profile

Wouldn't

 for f in ~/.bash_profile_*; do source $f; done

be sufficient?

Edit: Extra layer of ls ~/.bash_* simplified to direct bash globbing.

Oneliner (only for bash/zsh):

source <(cat *)

I agree with Dennis above; your solution should work (although the semicolon after "done" shouldn't be necessary). However, you can also use a for loop

for f in /path/to/dir*; do
   . $f
done

The command substitution of ls is not necessary, as in Dirk's answer. This is the mechanism used, for example, in /etc/bash_completion to source other bash completion scripts in /etc/bash_completion.d

for file in "$(find . -maxdepth 1 -name '*.sh' -print -quit)"; do source $file; done

This solution is the most postable I ever found, so far:

It does not give any error if there are no files matching
works with multiple shells including bash, zsh
cross platform (Linux, MacOS, ...)

You can use this function to source all files (if any) in a directory:

source_files_in() {
    local dir="$1"

    if [[ -d "$dir" && -r "$dir" && -x "$dir" ]]; then
        for file in "$dir"/*; do
           [[ -f "$file" && -r "$file" ]] && . "$file"
        done
    fi
}

The extra file checks handle the corner case where the pattern does not match due to the directory being empty (which makes the loop variable expand to the pattern string itself).
