Hi,
When we "grep" for a word in a file, it returns the lines containing the word that we searched for. Is there a way to display only the words and not the entire line containing them.
Thanks

I have a file that has the words I want to find in other files (but lets say I just want to find my words in a single file). Those words are IDs, so if my word is ZZZ4, outputs like aaZZZ4, ZZZ4bb, aaZZZ4bb, ZZ4, ZZZ, ZyZ4, ZZZ4.8 (or anything like that) WON'T BE USEFUL.

grapheme_substr
GRAPHEME_SUBSTR(3) 1 GRAPHEME_SUBSTR(3)grapheme_substr - Return part of a string
Procedural style
SYNOPSIS
int grapheme_substr (string $string, int $start, [int $length])
DESCRIPTION
Return part of a string
PARAMETERS
o $string
- The input string. Must be valid UTF-8.
o $start
- Start position in default grapheme units. If $start is non-negative, the returned string will start at the $start'th position in
$string, counting from zero. If $start is negative, the returned string will start at the $start'th grapheme unit from the end of
string.
o $length
- Length in grapheme units. If $length is given and is positive, the string returned will contain at most $length grapheme units
beginning from $start (depending on the length of string). If $length is given and is negative, then that many grapheme units will
be omitted from the end of string (after the start position has been calculated when a start is negative). If $start denotes a
position beyond this truncation, FALSE will be returned.
RETURN VALUES
Returns the extracted part of $string.

| | all the rest of the string according to $start |

EXAMPLES
Example #1
grapheme_substr(3) example
<?php
$char_a_ring_nfd = "axCCx8A"; // 'LATIN SMALL LETTER A WITH RING ABOVE' (U+00E5) normalization form "D"
$char_o_diaeresis_nfd = "oxCCx88"; // 'LATIN SMALL LETTER O WITH DIAERESIS' (U+00F6) normalization form "D"
print urlencode(grapheme_substr( "ao" . $char_a_ring_nfd . "bc" . $char_o_diaeresis_nfd . "O", 2, -1 ));
?>
The above example will output:
a%CC%8Abco%CC%88
