concatenate files with identifier

yonhk · #1 (**permalink**) 11-16-2008

Hi all

I concatenate files using cat. Each file contains only one csv data. for example,

file1
100

file2
200

cat file1 file2 > newfile

newfile
100
200

However, is there any way to insert identifier when using cat command?

for example,

newfile should have

file1 100
file2 200

Thanks in advance.

Try...

Code:

awk '{print FILENAME, $0}' file1 file2 > newfile
