Here's a simple command that will take
"hello","world","splat","diddle"
"he said "hello world" to ","his mate"and convert it to the following tab delimited file that can be COPYed using
psql. It even handles quotes inside fields. (^m and ^i are done by typing
CTRL+V CTRL+M and CTRL+V CTRL+I)
hello world splat diddle
he said "hello world" to his mate
sed 's/^"//' <t.txt|sed 's/"^m$//'|sed 's/","/^i/g'>t1.txt
