Question : Ruby regular expression - count piece of text in a text field

Hello
I have a csv file (approx 20000 lines) and I want to count the number of times the following text (On Hold)appears in a given field (Col4)  Example ....
Col1,      Col2 ,    Col3,    Col4,
1234,    "abcd",  12/05/08, "This ticket place On Hold 12/05/07 and etc etc again placed on hold etc etc"
4567,   "dfghfag", 14/05/08, "aaaaa \; On Hold-----On Hold rwg///sdf on hold ffff"
when written to new file the result set will be ...
Col1      Col2      Col3     Col4
1234,   "abcd",  12/05/08,  2,
4567,   "dfghfag", 14/05/08, 3

Any help much appreciated

Answer : Ruby regular expression - count piece of text in a text field

It might be not a bad idea to escape the \ in the path name
I use \\ instead

This works like a charm for me, using your input file
What is your ruby version?
