Concatenating several files in order

[caklich]

Hi, I currently have about 60 files in a directory, and I need to concatenate them in order. They have names such as:

OBS_DOMAIN101
OBS_DOMAIN102
OBS_DOMAIN103
....

If I were to just do a simple:

cat OBS_DOMAIN* > output.txt

would this concatenate them all in the order they are listed? If not, how would I do this fairly easily?

Thanks.

Yes, that cat command should expand the files in alphabetical order. Just bear in mind that it would be in the same order as

ls OBS_DOMAIN*

because it is the shell expansion that is the consistent piece.

You could also do:

sort OBS_DOMAIN*
