Removing double quotes in a file
Hi All,
I have a tab delimited file where each of the strings have double quotes.
The problem is that I have records which are in the following format:
"TEXAS" ""HOUSTON"" "123" "" "2625-39-39"
""MAINE"" "" "456" "I" "3737-39-82"
I would have to output another tab delimited file in the following fashion with the extra double quotes around the string removed:
"TEXAS" "HOUSTON" "123" "" "2625-39-39"
"MAINE" "" "456" "I" "3737-39-82"
This problem seems to persits across multiple fields and multiple rows.
Thanks for your help!!!
