From c04dff7965ed84bc57ea957ecad81fb902b7f146 Mon Sep 17 00:00:00 2001 From: Jeffery To Date: Sun, 6 Oct 2019 05:48:25 +0800 Subject: [PATCH] shinit: Add package This package adds support for /etc/shinit and ~/.shinit files, which contain commands to be run at the start of all interactive shells. (/etc/profile and ~/.profile are read for login shells only.) This is useful for those who regularly open non-login, interactive shells, for example users of GNU Screen or tmux. (This is based on a patch[1] I submitted for OpenWrt master, but there does not appear to be much interest in merging the change.) (This package uses the ENV shell variable, of which the POSIX standard has a brief description[2]. The dash manpage[3] also describes how the ENV variable is handled. (dash is the basis for busybox ash.))
