linux - (GNU) 使用变量查找 -mtime

Question

我正在尝试使用 -mtime +(variable) 查找文件，但每次我在 GNU 中执行以下命令时都会收到错误消息:

find: missing argument to `-mtime'

在 AIX 中试过，它成功了。

#------config-------#
cat hkeep.cfg
#<Directory to be purge>,<Days to Purge>
/home/fbmadm/logs,15

#------MAIN-------#
for line in `cat hkeep.cfg | grep -v "#"`;do
hkDir=`echo $line | awk -F"," '{print $1}'`
hkCnt=`echo $line | awk -F"," '{print $2}'` 

find $hkDir -mtime +$hkCnt
done

Answer 1

添加 echo line 可能会帮助您找出问题所在:

for line in `cat hkeep.cfg | grep -v "#"`;do
hkDir=`echo $line | awk -F"," '{print $1}'`
hkCnt=`echo $line | awk -F"," '{print $2}'` 
echo find $hkDir -mtime +$hkCnt
find $hkDir -mtime +$hkCnt
