How do I join two files vertically without any separator? I tried to use paste -d"" a b, but this just gives me a.
Sample file:
000 0 0 0
0001000200030004
10 20 30 40
2000 4000
.123
12.1

Method 1
paste use for null delimiter as defined by POSIX:
paste -d'' file1 file2
Using -d"" a b is the same as -d a b: the paste program sees three arguments -d, a and b, which makes a the delimiter and b the name of the sole file to paste.
If you’re on a GNU system (non-embedded Linux, Cygwin, …), you can use:
paste -d "" file1 file2
The form -d "" is unspecified by POSIX and can produce errors in other platforms. At least BSD and heirloom paste will report no delimiters error.
Method 2
The solution is:
paste -d "" a b
