Using the newline as the field separator, so $1 is line 1 and $2 is line 2
Using "," as the output field separator, so it adds an "," between the two when you print a,b
---------- Post updated at 12:16 PM ---------- Previous update was at 12:07 PM ----------
If you need an extra "," on the end you can just do print $1, $2, ""
It works partially good.
1. i've to implement this shell for hundreds of csv's, so i'm not quite sure on the number of lines for each record in these files. so print $1, $2 works well for two lines of record followed by a blank line. But this has to be dynamic.
2. It doesn't seem to add a extra delimiter to the end of each record, i.e before each blank line
¿How can i remove blank lines between all lines in a long text file?
Example
WrongFile.txt :
Line 1
Line 2
Line 3
CorrectFile.txt :
Line 1
Line 2
Line 3
Thanks in advance
