Combine (cat) all files in a tar.gz file


Hi,

Sorry if this is a an easy question but its go me beat at the mo after lots of trying.

I have a test.tar.gz file that contains 100 csv files.

I'm trying to work out how to unzip and extract all the files and cat them all together into 1 single csv file in one or possibly 2 commands...and leaving me with just the one csv file as the output...not all the extracted ones as well/

I *think* i need something like:

tar -xvf test.tar.gz | cat *.csv > singlefile.csv

but obviously this isn't correct .

I've played around for ages now with lots of variations and using "-" as well but the best I managed was to extract all the files AND create the singlefile as well....when what i need as the only output is a singlecsv file that contains all the lines within the 100 csv files.

Many thanks for any help or pointers.

Mike

Assuming everything goes well try:
Code:
tar -O -xf test.tar.gz > singlefile.csv
