Question

我有一个名为filename.${date}的文件列表，例如foo.20121102，我想使用bash工具集打印最新修改过的文件，该文件的时间戳到今天为止。

Answer 1

使用shell就像你问的那样：

for i in *; do
    if stat -c %y "$i" | grep -q "^$(date +%Y-%m-%d)"; then
        echo "$i has been modified or created today"
    else
        echo "$i has NOT been modified or created today"
    fi
done

Answer 2

# 24 hours * 60 minutes/hour * 60 seconds/minute
$threshhold = 86400;
$currenttime = time();
if( ($currenttime - $mtime) > $threshhold){
    # file was modified within 24 hours
}

对于午夜午夜后修改的文件：

if( $mtime > ($currenttime - ($currenttime % 86400)){
   # file was modified this calendar day
}
