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.

No, but this script solves the problem:

# no error checking
rm -f newfile
for i in file1 file2
do
   printf "%s " $i >> newfile
   cat "$i" >> newfile
done

Thanks a lot
However, I got

file1100
file2200

Is there any way to create CSV (comma delimited) or insert space?

I don't know what shell you are using (I'm using ksh), but this printf statement:

printf "%s " $i >> newfile

has a space after the %s format qualifer, and it works fine.

This example uses a pipe symbol instead of the space:

printf "%s|" $i >> newfile
