MSYS2 does not source .profile

Using MSYS2, if I run msys2_shell.bat, mintty opens a bash login shell, but ~/.profile does not get sourced.

Anyway if I run /bin/bash --login inside mintty, ~/.profile get sourced. Why?

The same happens if I run path\to\msys64\bin\bash.exe --login via Windows prompt instead of msys2_shell.bat.

PS: I tried also with .bash_profile.

The actual solution for me was to use ~/.bash_profile for msys instead of ~/.profile (or you can symlink it).

I was having the same issue.

I figured it out with the help of Dan in this ticket's comment thread: https://sourceforge.net/p/msys2/tickets/97

The solution is to edit the /etc/fstab

$ cat /etc/fstab
# For a description of the file format, see the Users Guide
# http://cygwin.com/cygwin-ug-net/using.html#mount-table

# DO NOT REMOVE NEXT LINE. It remove cygdrive prefix from path
none / cygdrive binary,posix=0,noacl,user 0 0

d:/Users/dparker /home/dparker ntfs binary,posix=0,user 0 0

Notice the last line is necessary to mount your home dir... I am not sure why you need to explicitly do this in /etc/fstab because it seems to mount it without it being there... but maybe it wasn't mounting it properly?

Hope this works for you like it did for me.

Disabling (renaming) system wide /etc/profile, ~/.profile is sourced.

After investigating /etc/profile I saw that, keeping it but commenting the function profile_d () ~/.profile is sourced. This function runs the scripts in /etc/profile.d/.

Disabling them individually I realized that the culprit is /etc/profile.d/bash_completion.sh.

It reads:

# Check for interactive bash and that we haven't already been sourced.
[ -z "$BASH_VERSION" -o -z "$PS1" -o -n "$BASH_COMPLETION_COMPAT_DIR" ] && return

# Check for recent enough version of bash.
bash=${BASH_VERSION%.*}; bmajor=${bash%.*}; bminor=${bash#*.}
if [ $bmajor -gt 4 ] || [ $bmajor -eq 4 -a $bminor -ge 1 ]; then
    [ -r "${XDG_CONFIG_HOME:-$HOME/.config}/bash_completion" ] && \
        . "${XDG_CONFIG_HOME:-$HOME/.config}/bash_completion"
    if shopt -q progcomp && [ -r /usr/share/bash-completion/bash_completion ]; then
        # Source completion code.
        . /usr/share/bash-completion/bash_completion
    fi
fi
unset bash bmajor bminor

The first line explains why when running the subshell (the second time) things work: environment variables are already set, so the script returns.

The problem is that bash_completion.sh runs /usr/share/bash-completion/bash_completion, which is really huge and it is difficult to grasp the problem.
