On Linux you can relink the deleted file with ln -L.
Code:
HIST_DATE="1900-01-01T00:00:00.000Z"
INC_DATE="2018-10-04T09:18:43.000Z"
fn=/tmp/file.tst
{
if rm $fn
then
  sed "s/$HIST_DATE/$INC_DATE/" >$fn ||
  ln -L /proc/$$/fd/1 $fn
fi
} <$fn

mb_eregi_replace - Replace regular expression with multibyte support ignoring case

SYNOPSIS
string mb_eregi_replace (string $pattern, string $replace, string $string, [string $option = "msri"]) DESCRIPTION
Scans $string for matches to $pattern, then replaces the matched text with $replacement. PARAMETERS
o $pattern - The regular expression pattern. Multibyte characters may be used. The case will be ignored. o $replace - The replacement text. o $string - The searched string. o $option -$option has the same meaning as in mb_ereg_replace(3). RETURN VALUES
The resultant string or FALSE on error. NOTES
Note The internal encoding or the character encoding specified by mb_regex_encoding(3) will be used as the character encoding for this function. Warning Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace(3)). Not taking care of this will most likely create remote code execution vulnerabilities in your application. SEE ALSO
