使用Awk+Printf处理autorep输出异常：多行合并及缺省字段填充求助

针对你遇到的两个核心问题，直接给出修改后的Shell脚本（核心基于awk处理），并说明关键逻辑：

autorep -J ALL | awk '
BEGIN {
    # 初始化所有字段为N/A，确保缺失字段有默认值
    job_name = "N/A"
    date_cond = "N/A"
    condition = "N/A"
    run_window = "N/A"
    # 打印格式化表头
    printf "%-20s %-15s %-30s %-20s\n", "Job Name", "Date Conditions", "Condition", "Run Window"
    printf "%s\n", "-------------------------------------------------------------------------------"
}

# 匹配Job起始行，触发上一个Job的输出并重置字段
/^Job Name:/ {
    if (job_name != "N/A") {  # 跳过初始状态，避免空行输出
        printf "%-20s %-15s %-30s %-20s\n", job_name, date_cond, condition, run_window
    }
    # 重置所有字段为初始状态，准备处理新Job
    job_name = "N/A"
    date_cond = "N/A"
    condition = "N/A"
    run_window = "N/A"
    # 提取当前Job名称
    split($0, arr, ": ")
    job_name = arr[2]
    next
}

# 匹配Date Conditions字段并赋值
/^Date Conditions:/ {
    split($0, arr, ": ")
    date_cond = arr[2]
    next
}

# 匹配Condition字段并赋值
/^Condition:/ {
    split($0, arr, ": ")
    condition = arr[2]
    next
}

# 匹配Run Window字段并赋值
/^Run Window:/ {
    split($0, arr, ": ")
    run_window = arr[2]
    next
}

# 处理最后一个Job，避免遗漏输出
END {
    if (job_name != "N/A") {
        printf "%-20s %-15s %-30s %-20s\n", job_name, date_cond, condition, run_window
    }
}
'

关键逻辑说明： #

1. 解决行合并问题：以Job Name:行作为每个Job的分割标记，每次识别到新Job时，先输出上一个Job的完整信息，再重置字段处理新Job，确保每个Job单独成行。
2. 解决缺失字段问题：所有字段初始化为N/A，仅当匹配到对应字段行时才覆盖赋值，未匹配到的字段保持N/A。
3. 格式化输出：用printf固定字段宽度，保证输出对齐美观。

预期输出示例： #

Job Name             Date Conditions   Condition                      Run Window            
-------------------------------------------------------------------------------
JOB_BACKUP_DB        0                 N/A                           N/A                  
JOB_SYNC_FILES       1                 FILE_READY                    WINDOW_OFFPEAK       
JOB_CLEAN_LOG        0                 N/A                           N/A
