Claude Code custom status line - shows model, directory, git branch, diff stats, and time

statusline.sh

#!/bin/bash
input=$(cat)

# Git info
BRANCH=$(git branch --show-current 2>/dev/null)
GIT_INFO=""
if [ -n "$BRANCH" ]; then
    GIT_INFO="$BRANCH"

    # Get diff stats (+/-)
    STATS=$(git diff --shortstat 2>/dev/null)
    if [ -n "$STATS" ]; then
        ADDS=$(echo "$STATS" | grep -oE '[0-9]+ insertion' | grep -oE '[0-9]+')
        DELS=$(echo "$STATS" | grep -oE '[0-9]+ deletion' | grep -oE '[0-9]+')

# Time with am/pm
TIME=$(date +"%I:%M %p")

echo "[$MODEL] ${DIR##*/}${GIT_INFO:+ | $GIT_INFO} | $TIME"
