Single quotes seem to fail in following cases:
As single quotes cannot be escaped with a backslash and double quotes like to evaluate, looks like double quotes is a best bet in my case.
Still investigating if we use sed double quoted "" escape normal character such as number 1 as \1 inside the sed, will it replace the \ and 1 as well, I know it \$ evaluates to $?

Bad example of \1 as it is back reference , let me use \A
echo "abc-A \ cde fg A \ hi" | sed -e "s/\A/ /g"
abc- \ cde fg \ hi
does not replace '\'
How can I use sed to replace a ctrl character such as 'new line' (\0a) to something else? Or any other good command can do this job?
Thanks,

get_magic_quotes_gpc
GET_MAGIC_QUOTES_GPC(3) 1 GET_MAGIC_QUOTES_GPC(3)get_magic_quotes_gpc - Gets the current configuration setting of magic_quotes_gpcSYNOPSIS
bool get_magic_quotes_gpc (void )
DESCRIPTION
Returns the current configuration setting of magic_quotes_gpc
Keep in mind that attempting to set magic_quotes_gpc at runtime will not work.
For more information about magic_quotes, see this security section.
RETURN VALUES
Returns 0 if magic_quotes_gpc is off, 1 otherwise. Or always returns FALSE as of PHP 5.4.0.
CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 5.4.0 | |
| | |
| | Always returns FALSE because the magic quotes |
| | feature was removed from PHP. |
| | |
+--------+---------------------------------------------------+
EXAMPLES
Example #1
get_magic_quotes_gpc(3) example
<?php
// If magic quotes are enabled
echo $_POST['lastname']; // O'reilly
echo addslashes($_POST['lastname']); // O\'reilly
// Usage across all PHP versions
if (get_magic_quotes_gpc()) {
$lastname = stripslashes($_POST['lastname']);
}
else {
$lastname = $_POST['lastname'];
}
// If using MySQL
$lastname = mysql_real_escape_string($lastname);
echo $lastname; // O'reilly
$sql = "INSERT INTO lastnames (lastname) VALUES ('$lastname')";
?>
NOTES
Note
If the directive magic_quotes_sybase is ON it will completely override magic_quotes_gpc. So even when get_magic_quotes_gpc(3)
returns TRUE neither double quotes, backslashes or NUL's will be escaped. Only single quotes will be escaped. In this case they'll
look like: ''
