I tried to extract the time from `date` with sed.
(I know it works with `date +%H:%M:%S` as well)
I got three solutions of which just one worked. I thought "+" should repeat the previous expression 1 or more times and {n} should repeat the previous expression n times.
I just want to know what's wrong with the examples.

replace the word "prod" with the word "special" but it may occur through the file naturally without a command, I only want it to happen when it has a specific command in front of it. The command will always look like this

Hi all,
I'm writing a script that replaces a value in a file. The file is formatted as follows:

From my understanding when using regex1|regex2 the matching process tries each alternative in turn, from left to right, and the first one that succeeds is used.

I am having trouble parsing rpm filenames in a shell script.. I found a snippet of perl code that will perform the task but I really don't have time to rewrite the entire script in perl. I cannot for the life of me convert this code into something sed-friendly:

curl_getdate
curl_getdate(3) libcurl Manual curl_getdate(3)NAME
curl_getdate - Convert a date string to number of seconds
SYNOPSIS
#include <curl/curl.h>
time_t curl_getdate(char *datestring, time_t *now );
DESCRIPTION curl_getdate(3) returns the number of seconds since the Epoch, January 1st 1970 00:00:00 in the UTC time zone, for the date and time that
the datestring parameter specifies. The now parameter is not used, pass a NULL there.
PARSING DATES AND TIMES
A "date" is a string containing several items separated by whitespace. The order of the items is immaterial. A date string may contain
many flavors of items:
calendar date items
Can be specified several ways. Month names can only be three-letter english abbreviations, numbers can be zero-prefixed and the
year may use 2 or 4 digits. Examples: 06 Nov 1994, 06-Nov-94 and Nov-94 6.
time of the day items
This string specifies the time on a given day. You must specify it with 6 digits with two colons: HH:MM:SS. To not include the time
in a date string, will make the function assume 00:00:00. Example: 18:19:21.
time zone items
Specifies international time zone. There are a few acronyms supported, but in general you should instead use the specific relative
time compared to UTC. Supported formats include: -1200, MST, +0100.
day of the week items
Specifies a day of the week. Days of the week may be spelled out in full (using english): `Sunday', `Monday', etc or they may be
abbreviated to their first three letters. This is usually not info that adds anything.
pure numbers
If a decimal number of the form YYYYMMDD appears, then YYYY is read as the year, MM as the month number and DD as the day of the
month, for the specified calendar date.

STANDARDS
This parser was written to handle date formats specified in RFC 822 (including the update in RFC 1123) using time zone name or time zone
delta and RFC 850 (obsoleted by RFC 1036) and ANSI C's asctime() format. These formats are the only ones RFC 7231 says HTTP applications
may use.
RETURN VALUE
This function returns -1 when it fails to parse the date string. Otherwise it returns the number of seconds as described.
If the year is larger than 2037 on systems with 32 bit time_t, this function will return 0x7fffffff (since that is the largest possible
signed 32 bit number).
Having a 64 bit time_t is not a guarantee that dates beyond 03:14:07 UTC, January 19, 2038 will work fine. On systems with a 64 bit time_t
but with a crippled mktime(), curl_getdate(3) will return -1 in this case.
