* Split ~/.shrc off stub ~/.shinit fileTom Ryder2016-12-031-0/+4
NetBSD sh(1) and possible others don't tolerate a `return` short-circuit for ENV, which means that because that implementation also sources ENV if set regardless of whether the shell is interactive or not, all of the interactive stuff in ~/.shrc and ~/.shrc.d gets uselessly sourced and loaded up for non-interactive invocations of sh(1). To work around this, I've set ENV to be a new ~/.shinit file instead, which sources the ~/.shrc file only if the shell is interactive. ~/.shinit is the filename suggested in the man page for NetBSD sh(1) and Debian dash(1) as well. NetBSD's documented behaviour seems to be contrary to POSIX 2003: > ENV: This variable, when and only when an interactive shell is > invoked, shall be subjected to parameter expansion (see Parameter > Expansion ) by the shell, and the resulting value shall be used as a > pathname of a file containing shell commands to execute in the > current environment. No matter; this works fine, and makes non-interactive invocations of sh(1) on NetBSD much faster.
