Unix file operations(shell script)
Hi,

I want to compare two files. Files will look like as follows:

file1:
ASDFGHJU|1234567890123456
QWERTYUI|3456789098900890
file2:
ZXCVBVNM|0987654321234567
POLKIJUYH|1234789060985478

output file should be:
ASDFGHJU|1234567890123456
QWERTYUI|3456789098900890


Thnaks in advance

if the files are sorted, look into 'man comm'
also look into 'man egrep'
