sed 替换 路径变量的问题.

cat sourcefile|sed "s:@PATH@:$userPath:g" >temp

echo find /opt/timer/errorlog/ -name \*.txt -mtime -1
  for TxtFile in $(find /opt/timer/errorlog/ -name \*.txt -mtime -1)
   do
     echo $TxtFile
     cat $TxtFile
     while read line
      do
          rm -rf /opt/$line
	  code=$?
	  echo $code
	  if [ "$code" -eq "0" ];then
		echo "delete successful"
		succ="$line""  successful" 
		echo $succ
		echo sed -i -e "s:${line}:${succ}:g" $TxtFile
		sed -i -e "s:${line}:${succ}:g" $TxtFile
          else
		echo "delete fail"
	  fi
      done<$TxtFile
   done
