unless use_default_names?; <<-EOS
|
|
All commands have been installed with the prefix 'g'.
|
|
|
|
A file that aliases these commands to their normal names is available
|
|
and may be used in your bashrc like:
|
|
|
|
source #{prefix}/aliases
|
|
|
|
But note that sourcing these aliases will cause them to be used instead
|
|
of Bash built-in commands, which may cause problems in shell scripts.
|
|
The Bash "printf" built-in behaves differently than gprintf, for instance,
|
|
which is known to cause problems with "bash-completion".
|
|
|
|
The man pages are still referenced with the g-prefix.
|
|
EOS
|
|
else
|
|
<<-EOS
|
|
Installing coreutils using the default names will cause the utilities to
|
|
shadow system-provided BSD tools if /usr/local/bin is ahead of /usr/bin in
|
|
the path.
|
|
|
|
This can cause problems in shell scripts.
|
|
|
|
Some software in Homebrew expects the system-provided tools to be first in
|
|
the path, and builds may fail if the coreutils verions are used instead.
