(GNU)使用变量查找-mtime

Question

我试图使用-mtime +(variable)查找文件，但每次在GNU中执行以下操作时，我都会得到一个错误：

查找:缺少“-时间”的论点

在AIX中尝试过，并且成功了。

#------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

添加一个echo line可以帮助您解决问题：

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
