Adding an extra date column in UNIX file

Hi All,

I have a file with only one column of data (without delimiter). For Ex:

Code:
cat temp.txt
22055
21088
93840
30990
50990
50950

I want to insert an additional column with current date as value. So, i have used below command but didn't get the result as excepted. Could onyone over here please help me in writing the current script command. Also i need to get rid of "space" after the comma delimiter.

Code:
awk -vd=`date +%Y%m%d` -F"," -OFS="," '{$2=d; print $1,$2}' temp.txt
22055, 20180928
21088, 20180928
93840, 20180928
30990, 20180928
50990, 20180928
50950, 20180928

NAME
pr - print file SYNOPSIS
pr [ option ] ... [ file ] ... DESCRIPTION
Pr produces a printed listing of one or more files. The output is separated into pages headed by a date, the name of the file or a speci- fied header, and the page number. If there are no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -h Take the next argument as a page header. -wn For purposes of multi-column output, take the width of the page to be n characters instead of the default 72. -ln Take the length of the page to be n lines instead of the default 66. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -sc Separate columns by the single character c instead of by the appropriate amount of white space. A missing c is taken to be a tab. -m Print all files simultaneously, each in one column, Inter-terminal messages via write(1) are forbidden during a pr. FILES
/dev/tty? to suspend messages. SEE ALSO
