Hide Forgot
My login information in the passwd file is as follows: aric:<password>:<userID>:<groupID>:Aric D. Blumer:/us/aric:/bin/sh I have the following in my $HOME/.profile: exec /us/aric/bin/linux/bash; This is so my version of bash is executed automatically as my shell. When I logged in with RH62 and prior, this worked just fine. When I log in with this setup in RH70, it hangs and I never see the bash prompt. I have to kill the exec'ed process with a -9. /bin/sh is a link to /bin/bash, so apparently bash is doing something strange during exec. If I change my $HOME/.profile to this: /us/aric/bin/linux/bash; exit; Then it doesn't hang.
This is actually the expected behavior: Bash executes your shell, which inherits the environment, therefore, it's a login shell and execs your .profile, as well, causing it to exit and exec itself, causing an endless loop.
Try again. What you claim is not true for three reasons: 1) It worked just fine with RedHat 6.2 2) There is no recursive spawing of bash (see below) 3) $HOME/.profile is only being read once. See the bash man page (I have a $HOME/.bash_profile which does not exec bash again). The following will prove there is not recursion: % cat ~/.profile echo Sourcing .profile exec /us/aric/bin/linux/bash %cat ~/.bash_profile echo Sourcing .bash_profile % rlogin localhost Last login: Thu Nov 2 08:47:55 from radar You have mail. Sourcing .profile If recursion were happening, I would see a bunch of "Sourcing .profile" on the screen. I do not.
It is not a recursion. This also happens if you exec /bin/tcsh. The simple fix I found was to copy /bin/bash (version 1) to /bin/sh to replace the symlink to bash2.
Fixed in 2.05-5
