Question

I need to put the contents of all *.as files in some specified folder into one big file.

How can I do it in Linux shell?

Answer 1

If you need all files in all subdirectories, th most robust way to do this is:

rm onebigfile
find -name  *.as  -print0 | xargs -0 cat >> onebigfile

This:

deletes onebigfile
for each file found, appends it onto onebigfile (this is why we delete it in the previous step -- otherwise you could end up tacking onto some existing file.)

A less robust but simpler solution:

cat `find -name  *.as ` > onebigfile

(The latter version doesn t handle very large numbers of files or files with weird filenames so well.)

Answer 2

You mean cat *.as > onebigfile?

Answer 3

Not sure what you mean by compile but are you looking for tar?
