From 9049ab1a3b8bd27eda01c605b9dc4d2993e73caf Mon Sep 17 00:00:00 2001 From: Jörg Thalheim Date: Tue, 27 Sep 2016 21:18:29 +0200 Subject: zsh: do not export HISTFILE, HISTSIZE, SAVEHIST Every interactive zsh sources /etc/zshrc (see STARTUP/SHUTDOWN FILES in zshautll(1)) Therefor every interactive zsh process will respect the content of these variables. Using `export` will also lead to child processes inheriting this value. This leads to problems, if other interactive shells are spawned such as bash, because they use an incomptabible history format (without timestamps). There seems to be also cases, where the local HISTSIZE in ~/.zshrc is not sourced but /etc/zshrc, which leads to history truncation in other shells. --- nixos/modules/programs/zsh/zsh.nix | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'nixos') diff --git a/nixos/modules/programs/zsh/zsh.nix b/nixos/modules/programs/zsh/zsh.nix index 91cd84416921..d81f63c2acca 100644 --- a/nixos/modules/programs/zsh/zsh.nix +++ b/nixos/modules/programs/zsh/zsh.nix @@ -102,9 +102,9 @@ in interactiveShellInit = '' # history defaults - export SAVEHIST=2000 - export HISTSIZE=2000 - export HISTFILE=$HOME/.zsh_history + SAVEHIST=2000 + HISTSIZE=2000 + HISTFILE=$HOME/.zsh_history setopt HIST_IGNORE_DUPS SHARE_HISTORY HIST_FCNTL_LOCK -- cgit 1.4.1
