Hi
You will need two text utilities {dos2unix and sed} to do this in the simplest
way. They are fairly standard text utilities and are probably already on your
machine.
This is how I would do it :
sed "s/\"//g" file_name.txt \| dos2unix \| pgsql -c "COPY table_name FROM STDIN USING DELIMITERS ',';" db
Where "file_name.txt" is the csv file you want to import and "table_name" is
the previously created table you want to insert the data into and db is the
database name.
How this works is "sed" {stream editor} removes all the double quote
characters '"' then pipes the output through "dos2unix" which converts all the
CRLF {DOS EOL} sequences into CR {UNIX EOL} characters, then pipes the data to
"pgsql" with a command that does a bulk insert into the table of the database
you have selected.
