Find duplicate values in specific column and delete all the duplicate values
Dear folks
I have a map file of around 54K lines and some of the values in the second column have the same value and I want to find them and delete all of the same values. I looked over duplicate commands but my case is not to keep one of the duplicate values. I want to remove all of the same values in the specific column.
Say part of my input data is like this example:
my desire output is:

NAME
cyr_expire - expire messages and duplicate delivery database entries
SYNOPSIS
cyr_expire [ -C config-file ] [ -D delete-days ] -E expire-duration [ -X expunge-days ] [ -p mailbox-prefix ] [ -v ]
DESCRIPTION
Cyr_expire is used to expire messages and duplicate delivery database entries. Cyr_expire also cleanses mailboxes of partially expunged
messages (when using the "delayed" expunge mode). The expiration of messages is controlled by the /vendor/cmu/cyrus-imapd/expire mailbox
annotation which specifies the age (in days) of messages in the given mailbox that should be deleted. Any duplicate delivery database
entries which correspond to the mailbox are also deleted at the same frequency.
The value of the /vendor/cmu/cyrus-imapd/expire annotation is inherited by all children of the given mailbox, so an entire mailbox tree can
be expired by seting a single annotation on the root of that tree. If a mailbox does not have a /vendor/cmu/cyrus-imapd/expire annotation
set on it (or does not inherit one), then no messages are expired from the mailbox.
Cyr_expire reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.
OPTIONS -C config-file
Read configuration options from config-file.
-D delete-duration
Remove previously deleted mailboxes older than delete-duration (when using the "delayed" delete mode). The value can be a floating
point number, and may have a suffix to specify the unit of time. If no suffix, the value is number of days. Valid suffixes are d
(days), h (hours), m (minutes) and s (seconds).
-E expire-duration
Prune the duplicate database of entries older than expire-duration. This value is only used for entries which do not have a corre-
sponding /vendor/cmu/cyrus-imapd/expire mailbox annotation. Format is the same as delete-duration.
-X expunge-duration
Expunge previously deleted messages older than expunge-duration (when using the "delayed" expunge mode). Format is the same as
delete-duration.
-x Do not expunge messages even if using delayed expunge mode (reduces the IO hit considerably, allowing you to run cyr_expire fre-
quently to clean up the duplicate database without overloading your server)
-p mailbox-prefix
Only find mailboxes starting with this prefix. e.g. "user.justgotspammedlots"
-v Enable verbose output.
-a Skip the annotation lookup, so all /vendor/cmu/cyrus-imapd/expire annotations are ignored entirely. It behaves as if they were not
set, so only expire-days is considered for all mailboxes.
