Find Common Values Across Two Files

Hi All,

I have two files like below:

File1
Code:
MYFILE_28012012_1112.txt|4
MYFILE_28012012_1113.txt|51
MYFILE_28012012_1114.txt|57
MYFILE_28012012_1115.txt|57
MYFILE_28012012_1116.txt|57
MYFILE_28012012_1117.txt|57

File2
Code:
MYFILE_28012012_1110.txt|57
MYFILE_28012012_1111.txt|57
MYFILE_28012012_1112.txt|57
MYFILE_28012012_1115.txt|57
MYFILE_28012012_1116.txt|57
MYFILE_28012012_1117.txt|57

I want to match value of first column in file 1 with file 2 and wish to get the output as below:

Code:
MYFILE_28012012_1112.txt|4|57
MYFILE_28012012_1115.txt|57|57
MYFILE_28012012_1116.txt|57|57
MYFILE_28012012_1117.txt|57|57

Any help on this will be highly appreciated
Thanks
Angshuman
