    @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

    HBD, John E. Hopcroft! Hopcroft received the 1986 #ACMTuringAward with Robert E. Tarjan, for fundamental achievements in the design and analysis of algorithms and data structures. Watch Hopcroft explain how he was hired for his first academic job, at Princeton, without having published a single paper: https://youtu.be/aCs1SqHUdzk?si=8VcQvNJR-WivTWf4
