I think what is happening is the aliases in .shrc are not read directly by
bash unless invoked as sh, and the .shrc assigned to ENV is only read for
non-login shells; I'm not sure why they wouldn't work when entered in
.bash_profile, but the fact that they don't suggests a conflict between
the files the commands are entered in and the order in which they are
read.
When invoked as bash (not sh) the start-up files that bash reads for a
login shell are, in order:
i) /etc/profile
and then the first of any of the following that exists:
ii) ~/.bash_profile OR
iii) ~/.bash_login OR
iv) ~/.profile
Non-login interactive bash shells (when changing or starting new shells
during a session) read only ~/.bashrc.
Non-login non-interactive bash shells (ie-when launched from inside a
script) check the startup file in $BASH_ENV, or $ENV if that doesn't
exist.
An easy way to make sure all three invocations of bash reference the same
start-up file is:
i) use .bashrc as your customized startup file
ii) create a .bash_profile containing only:
export BASH_ENV=~/.bashrc
if [ -f ~/.bashrc ]; then source ~/.bashrc; fi
This way, after reading /etc/profile a login shell will read the first
file found, ~/.bash_profile, which in turn reads ~/.bashrc
Non-login interactive shells will read ~/.bashrc as usual
Non-login non-interactive shells will read the ~/.bashrc assigned in
$BASH_ENV.
Cheers,
Viktor
