find duplicate string in many different files
I have more than 100 files like this:

HTML Code:
SVEAVLTGPYGYT	2	
SVEGNFEETQY	10	
SVELGQGYEQY	28	
SVERTGTGYT	6	
SVGLADYNEQF	21	
SVGQGYEQY	32	
SVKTVLGYEQF	2	
SVNNEQF	       12	
SVRDGLTNSPLH	3	
SVRRDREGLEQF	11	
SVRTSGSYEQY	17	
SVSVSGSPLQETQY	78	
SVVHSTSPEAF     59
SVVPGNGYT	75
There is a string in $1 and its frequency in $2.
I have two questions. How can I merge these file into one file, which include all the string in $1 and each frequency in different fields?

How can I find the same string included in the 100 files, and output its each frequency?

I can do this using awk between two files, but failed to deal with so many.

Thank you!

NAME

       ntptime - read and set kernel time variables

SYNOPSIS

       ntptime [ -MNchr ] [ -e est_error ] [ -f frequency ] [ -m max_error ] [ -o offset ] [ -s status ] [ -t time_constant] [ -T tai_offset ]

DESCRIPTION

       This  program  is  useful  only	with special kernels described in the A Kernel Model for Precision Timekeeping page. It reads and displays
       time-related kernel variables using the ntp_gettime() system call. A similar display can be obtained using the ntpdc program  and  kerninfo

       -h      Display help information.

       -m max_error
	       Specify max possible errors, in microseconds.

       -o offset
	       Specify clock offset, in microseconds.

       -r      Display Unix and NTP times in raw format.

       -s status
	       Specify clock status. Better know what you are doing.

       -t time_constant
	       Specify time constant, an integer in the range 0-10.

       -M      Switch to microsecond mode.

       -N      Switch to nanosecond mode.

       -T tai_offset
