hi, i have a file that has about 4500 rows. this was an old microsoft access databse and what i am trying to do is take out the old extra \n newline characters but not take out the "true" newline character. I will explain.


i was trying to write a regular expression, but that was not working so i thought PERL would be the best option. The collums are seperated by commas.

Here is the dataset that i am working against.

144,20050892.0, Replacement of IN-FOCUS projector-Bldg 123, Replace malfunctioning In-Focus projector with new one.,- In-Focus projectors are used to project slideshows and other pertinent data to fron mountred screens.

- Intermittent power up problem, kicks on and off. This project was originally in Sept 2001.
- Bulbs have been replaced when it does work it is barely readable.,Infocus LP 640 XGA LCD Multimedia Projector $1699 EA

Pretty much i need to remove the extra \n newline characters without removing the end one. This is what the dataset should look like.

The fist column, in this case is 144, and they are numbered sequentially. So the next one would be 145.

can i do this with standard UNIX regular expressions or would PERL be better?

Thanks
