It works, but i don't want to print the value. How do i give the value of b to the grep command without the echo?

lastlog
LASTLOG(8) System Management Commands LASTLOG(8)
NAME
lastlog - reports the most recent login of all users or of a given user
SYNOPSIS
lastlog [options]
DESCRIPTION
lastlog formats and prints the contents of the last login log /var/log/lastlog file. The login-name, port, and last login time will be
printed. The default (no flags) causes lastlog entries to be printed, sorted by their order in /etc/passwd.
OPTIONS
The options which apply to the lastlog command are:
-b, --before DAYS
Print only lastlog records older than DAYS.
-h, --help
Display help message and exit.
-t, --time DAYS
Print the lastlog records more recent than DAYS.
-u, --user LOGIN|RANGE
Print the lastlog record of the specified user(s).
The users can be specified by a login name, a numerical user ID, or a RANGE of users. This RANGE of users can be specified with a min
and max values (UID_MIN-UID_MAX), a max value (-UID_MAX), or a min value (UID_MIN-).
If the user has never logged in the message ** Never logged in** will be displayed instead of the port and time.
Only the entries for the current users of the system will be displayed. Other entries may exist for users that were deleted previously.
NOTE
The lastlog file is a database which contains info on the last login of each user. You should not rotate it. It is a sparse file, so its
size on the disk is usually much smaller than the one shown by "ls -l" (which can indicate a really big file if you have in passwd users
with a high UID). You can display its real size with "ls -s".
FILES
/var/log/lastlog
Database times of previous user logins.
CAVEATS
Large gaps in UID numbers will cause the lastlog program to run longer with no output to the screen (i.e. if in lastlog database there is
no entries for users with UID between 170 and 800 lastlog will appear to hang as it processes entries with UIDs 171-799).
