Top Forums Shell Programming and Scripting Uniq or sort -u or similar only between { } Post 302924248 by MadeInGermany on Friday 7th of November 2014 07:34:32 AM

Code:
awk '
/\}/ {block=0; delete S}
(block==1) {
  if ($0 in S) {next} else {S[$0]}
}
{print}
/\{/ {block=1}
' input

The array S stores all encountered strings (where string is $0 i.e. the current line). At the end of the block it is deleted, so each block is separate.
The following stores the previous value in a simple variable S, and will only suppress adjacent duplicate lines.
Code:
awk '
/\}/ {block=0; found=0}
(block==1) {
  if (found==1 && $0==S) {next} else {S=$0; found=1}
}
{print}
/\{/ {block=1}
' input

The following input file demonstrates the difference:
Code:
{
   aaa
   bbb
   aaa
}

aaa
bbb
aaa

{
   aaa
   aaa
   ccc
}

NB awk uses ERE, and { and } have a special meaning. So it should be \{ and \}.
Then in principal my 1st sample is identical with Rudi's 2nd sample.

FPUTCSV(3)								 1								FPUTCSV(3)

fputcsv - Format line as CSV and write to file pointer

SYNOPSIS
int fputcsv (resource $handle, array $fields, [string $delimiter = ","], [string $enclosure = '"'], [string $escape_char = " DESCRIPTION
fputcsv(3) formats a line (passed as a $fields array) as CSV and write it (terminated by a newline) to the specified file $handle. PARAMETERS
o $handle -The file pointer must be valid, and must point to a file successfully opened by fopen(3) or fsockopen(3) (and not yet closed by fclose(3)). o $fields - An array of values. o $delimiter - The optional $delimiter parameter sets the field delimiter (one character only). o $enclosure - The optional $enclosure parameter sets the field enclosure (one character only). o $escape_char - The optional $escape_char parameter sets the escape character (one character only). RETURN VALUES
Returns the length of the written string or FALSE on failure. CHANGELOG
+--------+---------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------+ | 5.5.4 | | | | | | | The $escape_char parameter was added | | | | +--------+---------------------------------------+ EXAMPLES
Example #1 fputcsv(3) example <?php $list = array ( array('aaa', 'bbb', 'ccc', 'dddd'), array('123', '456', '789'), array('"aaa"', '"bbb"') ); $fp = fopen('file.csv', 'w'); foreach ($list as $fields) { fputcsv($fp, $fields); } fclose($fp); ?> The above example will write the following to file.csv: aaa,bbb,ccc,dddd 123,456,789 """aaa""","""bbb""" NOTES
Note If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh computer, enabling the auto_detect_line_endings run-time configuration option may help resolve the problem. SEE ALSO
