Fix for fish and gnome-shell gkr-pam: unable to locate daemon control file

[igo95862]

I saw you linked an bug report on Arch Wiki fish shell with an issues between the bashrc fish launch script and gnome shell.

I debugged it a little bit and came up with the fix:

if [[ $(ps --no-header --pid=$PPID --format=cmd) != "fish" && -z ${BASH_EXECUTION_STRING} ]]
then
	exec fish
fi

For some reason gnome shell launches the bash with -c commands and manually sources bashrc. BASH_EXECUTION_STRING will indicate that bash was launched with -c arguments.

I believe this is a Fedora problem. I never had an issue with this on Arch even though I have been running GNOME for quite some time.

Might be different PAM configuration as well.
