Concatenate files in order with type

Question

I am trying to use this command:

type *.dump > total

in order to concatenate my .dump files into total.

However, the numbering of concatenation is wrong. For instance the files in order are:

cascade1.dump cascade10.dump cascade 11.dump

as opposed to 1, 2, 3, etc.

Can someone help me figure out the numbering?

Answer 1

GNU sort has a way to do natural sorting, called version sorting in its case:

-V, --version-sort          natural sort of (version) numbers within text

So you can do the following:

$ ls foo*
foo0  foo1  foo10  foo11  foo12  foo13  foo14  
foo15  foo2  foo3  foo4  foo5  foo6  foo7  foo8  foo9

$ ls foo* | sort -V
foo0
foo1
foo2
foo3
foo4
foo5
foo6
foo7
foo8
foo9
foo10
foo11
foo12
foo13
foo14
foo15

$ ls foo* | sort -V | xargs cat > total

Answer 2

This should work:

ls -rt *.dump | xargs cat > total

It orders the *.dump files by time before concatenation.
