echo '"Im a test",dont remote this,"another test",dont remove this too' | sed 's/".*"//g'
to print:
Code:
dont remote this,dont remove this too
In other words I want to replace everything in quotes, including an optional , with blank. Also it should read 2 strings of quotes: "Im a test" and "another test" rather than one long string: "Im a test",dont remote this,"another test"
Firstly, why you got your result, * is greedy bey default, hence it looks for the largest match possible to your expression, so ".*" matches "Im a test",dont remote this,"another test". You confirm this with a simple grep
with colouring turned on:
Code:
$ echo '"Im a test",dont remote this,"another test",dont remove this too' | grep '".*"'
"Im a test",dont remote this,"another test",dont remove this too
As for [^"], ^ means the start of the line when not escaped or in square brackets. When the first item in square brackets it negates anything else included in them, so in this case it says return everything that is not "
The reason for escaping the ? is so sed does not interpret it as a ? but so it says zero or one of the preceding character, ie. the comma (,). Alternative you can remove the escape if you use the -r option for sed.
