From 44b7d104b403062bf9ad57363f76464e355bc9a2 Mon Sep 17 00:00:00 2001 From: Nicolas Mattia Date: Mon, 21 Feb 2022 13:35:51 +0100 Subject: [PATCH] Document usage of MANPATH in nix-profile.sh While trying to figure out how `nix-env`/`nix profile` work I had a hard time understand how man pages were being installed. Took me quite some time to figure this out, thought it might be useful to others too! --- scripts/nix-profile.sh.in | 3 +++ 1 file changed, 3 insertions(+) diff --git a/scripts/nix-profile.sh.in b/scripts/nix-profile.sh.in index 8cba1c522..45cbcbe74 100644 --- a/scripts/nix-profile.sh.in +++ b/scripts/nix-profile.sh.in @@ -24,6 +24,9 @@ if [ -n "$HOME" ] && [ -n "$USER" ]; then export NIX_SSL_CERT_FILE="$NIX_LINK/etc/ca-bundle.crt" fi + # Only use MANPATH if it is already set.
