Merge command

[harpal]

I have loads of PRODUCTS.DATA files sitting in a archive directory all with date extensions what I would like to know is if I have the following below

PRODUCTS.DATA.011012
PRODUCTS.DATA.011013
PRODUCTS.DATA.011014
PRODUCTS.DATA.011015

can I merge these 4 files in one big PRODUCTS.DATA file?

is there a unix command which will allow me to do this.

Just do:

cat filename1 filename2 etc > PRODUCTS.DATA

The cat command concatenates (joins) the files in the list and the > outputs them to the new PRODUCTS.DATA file. To append to the PRODUCTS.DATA file if it already exists use >> rather than >

Your original files will still exist after this process, so you can decide what to do with them (ie delete, archive to tape etc).

HTH.
