sed 脚本分隔符引起的问题unknown option to `s'

执行脚本sed:

source ../../conf.properties

target_dir=data_process_$DATE
current_date=$(date +%Y/%m/%d/%H)
echo $current_date
rm -rf $target_dir > /dev/null 2>&1
mkdir $target_dir

# Generate the ql from the merge_table directory
for ql in `ls merge_table | grep ql`
do
  sed "s/%CHINADAASREDUCETASKS%/$MAPRED_REDUCE_TASKS/g" merge_table/$ql > $target_dir/$ql
  sed -i "s/%CHINDAASDATE%/$DATE/g" $target_dir/$ql
  sed -i "s/%current_date%/$current_date/g" $target_dir/$ql
done

 报错如下：

 

 

sed: -e expression #1, char 25: unknown option to `s'

 

 

原因：

因为路径里面包含有“/”作为分隔符，这会和sed的替换操作的分隔符“/”引起混淆；所以改为#，只要不使用“/”做分隔符就可以解决这个问题。
