merge lines of file by using paste

Linux is always so powerful to do something, in my life. And it makes my life ease...

Sometimes, I need a special tool to merge two or multiple files into a file. So here is the

neat solution for that.

$ more {1,2}.dat
::::::::::::::
1.dat
::::::::::::::
1
2
3
::::::::::::::
2.dat
::::::::::::::
A
B
C
$ paste  {1,2}.dat
1       A
2       B
3       C
$ paste  -d" " {1,2}.dat
1 A
2 B
3 C
$ paste  -d"," {1,2}.dat
1,A
2,B
3,C

$ paste  *.dat
1       A
2       B
3       C
