Note I was talking about setting up a /etc/skel/ file for ~/.xsession with #!/bin/bash already included. Or rather why that would not work. > Well the exec -l $SHELL -c "$STARTUP" solution fixes that Agreed. > provided /bin/sh exec accepts the option like bash. That was the problem with /bin/sh. /bin/sh is not required to accept args like /bin/bash. In which case the script interpreter must simply be #!/bin/bash. Using 'exec -l' plus using #!/bin/bash works. At least I can't refute it after thinking about it for the day. > To make it work with other shells would not be hard as the -l option > to exec just sets the zero'th argument of the command to '-' which > appears to be a convention shared with ash at least. > From the ash man page: > > If the first character of argument zero to the shell is > ``-'', the shell is assumed to be a login shell, and the > files /etc/profile and .profile are read if they exist. I think you missed the point I was making. I was not arguing that shells would ignore the leading '-' and not be invoked as a login shell. I was arguing that 'exec -l' required #!/bin/bash and would not work reliably with #!/bin/sh because /bin/sh might not be bash. Bob
