个人博客自动更新脚本

在使用jekyll的Chirpy theme构建个人博客的时候，经常需要commit和push，重复性的劳动是一件很无聊的事，于是想到可以用一个bash脚本去自动化完成这一工作。

脚本

#!/bin/bash
REPO_PATH="/path/to/your/repo"
LOG_FILE="/path/to/your/log/directory/blog-auto-commit.log"

cd "$REPO_PATH" || {
    echo "Failed to change to repository directory" >> "$LOG_FILE"
    exit 1
}

DATE=$(date +"%Y-%m-%d %H:%M:%S")

# Function to attempt git push with retry
git_push_with_retry() {
    local max_attempts=3
    local attempt=1
    local delay=30

    while [ $attempt -le $max_attempts ]; do
        if git push origin main >> "$LOG_FILE" 2>&1; then
            return 0
        else
            echo "Push attempt $attempt failed, waiting $delay seconds..." >> "$LOG_FILE"
            sleep $delay
            attempt=$((attempt + 1))
        fi
    done
    return 1
}

if git status --porcelain | grep '^.*$' >/dev/null; then

    git add . >> "$LOG_FILE" 2>&1
    
    if git commit -m "Auto-commit: $DATE" >> "$LOG_FILE" 2>&1; then
        if ! git_push_with_retry; then
            echo "Failed to push after multiple attempts at $DATE" >> "$LOG_FILE"
            exit 1
        fi
    else
        echo "Failed to commit changes at $DATE" >> "$LOG_FILE"
        exit 1
    fi
else
    echo "No changes to commit at $DATE" >> "$LOG_FILE"
fi

运行

可以将脚本放置于~/bin目录下，并且赋予其执行权限：chmod +x script.sh 。然后需要讲该脚本加入cron job中，运行crontab -e，填入以下内容：

0 * * * * ~/bin/script.sh
