Host doesn't have 'tac' command. For now what I tried is -

Code:
grep 'string' file | tail -1

Was wondering if sed might have a better way.

ICONV_STRRPOS(3)							 1							  ICONV_STRRPOS(3)

iconv_strrpos - Finds the last occurrence of a needle within a haystack

SYNOPSIS
int iconv_strrpos (string $haystack, string $needle, [string $charset = ini_get("iconv.internal_encoding")]) DESCRIPTION
Finds the last occurrence of a $needle within a $haystack. In contrast to strrpos(3), the return value of iconv_strrpos(3) is the number of characters that appear before the needle, rather than the offset in bytes to the position where the needle has been found. The characters are counted on the basis of the specified character set $charset. PARAMETERS
o $haystack - The entire string. o $needle - The searched substring. o $charset - If $charset parameter is omitted, $string are assumed to be encoded in iconv.internal_encoding. If $haystack or $needle is not a string, it is converted to a string and applied as the ordinal value of a character. RETURN VALUES
Returns the numeric position of the last occurrence of $needle in $haystack. If $needle is not found, iconv_strrpos(3) will return FALSE. Warning This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function. SEE ALSO
strrpos(3), iconv_strpos(3), mb_strrpos(3). PHP Documentation Group ICONV_STRRPOS(3)
