I have 3 files in directory "work" which will be pumped on daily basis.

files are as shown below:

```
ZNAMI DOWN COND RESULT_17-08-2015.csv
ZNAMI UP CND RESULT_18-08-2015.csv
ZNAMI DOWN COND RESULT_17-08-2015.csv

```

These files have many rows with just ",,,,,,,,," as input along with actual data.

What I need to perform is as below:

1. open each file [should be dynamic as everyday , date part changes].
2. Remove the lines with ",,,,,,,,,".
3. Get the line count.

I tried `wc -l *.csv` but it does not give the total count of all lines.
I also tried `sed -i ",,,,,,,,,"d *.csv` to remove the lines . But it is not working.
