Greetings all. :)
I would like to use sed to join all non-blank lines together in a particular file. I was thinking I could do this by simply replacing the terminating, new-line character on every line which is not blank, but I must be missing something in my sed line:

I want to use SED to replace all new line characters of a file, I googled and found this one liner
sed '{:q;N;s/\n//g;t q}' infile
what do :q;N; and t q mean in this script? (6 Replies)
Can anyone explain the below sed oneliner?
sed -e ':a' -e '$q;N;11,$D;ba'
It works same as tail command.
I just want to know how it works.
Thanks

I have a data base of part numbers:
AAA Thing1
BBB Thing2
CCC Thing3
File one is a list of part numbers:
AAA234
BBB678
CCC2345
Is there a sed one-line that would compare a data base with and replace the part numbers so that the output looks like this?
AAA234 Thing1
BBB678 Thing2... (5 Replies)

Hi,
I have the following command.(Delete all trailing blank lines at the end of a file.)
sed -e :a -e '/^\n*$/{$d;N;ba' -e '}'
I don't understand the logic of this command and also I don't understand why -e is used.
Can you please let me know the logic of this command and why three -e... (5 Replies)

MB_CONVERT_CASE(3) 1 MB_CONVERT_CASE(3)mb_convert_case - Perform case folding on a stringSYNOPSIS
string mb_convert_case (string $str, int $mode, [string $encoding = mb_internal_encoding()])
DESCRIPTION
Performs case folding on a string, converted in the way specified by $mode.
PARAMETERS
o $str
- The string being converted.
o $mode
- The mode of the conversion. It can be one of MB_CASE_UPPER, MB_CASE_LOWER, or MB_CASE_TITLE.
o $encoding
-The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.
RETURN VALUES
A case folded version of $string converted in the way specified by $mode.
UNICODE
By contrast to the standard case folding functions such as strtolower(3) and strtoupper(3), case folding is performed on the basis of the
Unicode character properties. Thus the behaviour of this function is not affected by locale settings and it can convert any characters that
have 'alphabetic' property, such as A-umlaut (A).
For more information about the Unicode properties, please see http://www.unicode.org/unicode/reports/tr21/.
EXAMPLES
Example #1
mb_convert_case(3) example
<?php
$str = "mary had a Little lamb and she loved it so";
$str = mb_convert_case($str, MB_CASE_UPPER, "UTF-8");
echo $str; // Prints MARY HAD A LITTLE LAMB AND SHE LOVED IT SO
$str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8");
echo $str; // Prints Mary Had A Little Lamb And She Loved It So
?>
Example #2
mb_convert_case(3) example with non-Latin UTF-8 text
<?php
$str = "Txiotn a
nE Baos unuvn yn, dpaokeCei unp vw0po kuvs";
$str = mb_convert_case($_tr, MB_CASE_UP_ER, "UTF_8"); _ _
echo $str; // Prints TXI>TH A/TTHH BAO> YHMNH | H, /PA>KE/EI YTTP NOOPO KYN>
$str = mb_convert_case($str, MB_CASE_TITLE, "U_F-8");
echo $str; // Prints Txiotn A
nE Baoo Ynuvn | n, /paokeCei Ynp Nw0po Kuvo
?>
