I'm trying to debug what bash does on login initialization for Linux. I've read that "bash -x" will make bash print out what it's doing, but it doesn't print commands in sourced files like "set -x" does. I can't use "set -x" because initialization runs before I can call it. "bash -x" seems to recurse fine on OS X, but that might be because of the bash versions.
OS X: 3.2.48
Here's an excerpt of the non-recursing behavior on Linux:
bash -l -x -c 'echo 1' # ... snip ... + for i in '/etc/profile.d/*.sh' + '[' -r /etc/profile.d/vim.sh ']' + '[' '' ']' + . /etc/profile.d/vim.sh + for i in '/etc/profile.d/*.sh' + '[' -r /etc/profile.d/which-2.sh ']' + '[' '' ']' + . /etc/profile.d/which-2.sh # ... snip ...
Notice how /etc/profile.d/vim.sh is sourced, but its commands aren't printed. Is there a workaround without upgrading? Is this caused by the version difference?
