    @mwl@io.mwl.io’s post made me revisit RCS in a very small role: a safety net for individual files.Paired with nvi, a tiny wrapper lets me snapshot configs before risky edits. Simple, local, no magic.Example wrapper I’m using:#!/bin/sh## safeedit — RCS-backed safe editing with nvi#set -eif [ $# -ne 1 ]; then echo "usage: safeedit <file>" >&2 exit 1fiFILE="$1"if [ ! -f "$FILE" ]; then echo "safeedit: file not found: $FILE" >&2 exit 1fiDIR=$(dirname "$FILE")BASE=$(basename "$FILE")RCS_DIR="$DIR/RCS"RCS_FILE="$RCS_DIR/$BASE,v"mkdir -p "$RCS_DIR"chmod 700 "$RCS_DIR"if [ ! -f "$RCS_FILE" ]; then ci -l "$FILE"else ci -u "$FILE" || true co -l "$FILE"fiexec nvi "$FILE"nvi protects the session; RCS protects the decision.Original post by @mwl@snac.bsd.cafe: https://io.mwl.io/@mwl/115814245521209100#nvi #RCS #Unix #SysAdmin #ConfigManagement
