Hi,

I have multiple files, say, test1.dat, test2.dat, etc. Each file has only one record. I tried:

cat test*.dat > final.dat

The records from each file were combined into one line instead of separate lines in the final.dat file.

How do I combined the record from each file while appending new line after each record?

Thanks,

Mike
 
Hi

I know no way to do it with [tt]cat[/tt], so I would use AWK :
Code:
awk 'FNR==1&&NR!=1{print""}1' test*.dat > final.dat
Tested with [tt]gawk[/tt] and [tt]mawk[/tt].

Alternatively you could take a look at [tt]paste[/tt], especially if yours support [tt]-s[/tt] ( [tt]--serial[/tt] ) and [tt]-d[/tt] ( [tt]--delimiters[/tt] ) switches.


Feherke.
 
Maybe
Code:
for i in test*.dat ; do cat $i ; echo "" ; done > final.dat
