Catting to make one file

[maxcrook]

I have 10 files all called file1, file2, file3 etc

I need to automate the process so that the following can be done automatically.

I start with the highest numerical file number and cat that to the next highest in sequence, then remove the highest like so......

cat file10 >> file 9
rm file10
cat file9 >> file8
rm file9
etc..............
Is there an easy way to do this ?

So far i have tried several ways and each one deletes the end file created - file1!

Help me please I am losing the will to live !

x=10
while [ "$x" -ne "1" ] ; do
y=`echo "$x-1"|bc`
cat $x >>$y
rm $x
x=$y
done

Thanks,I tried running this and the message:

cat: 0652-050 Cannot open 10.

was displayed. Also files are called file_1 not file1 sorry.

I created 10 files called "1" thru "10" for testing.

Change the 3rd line of the script to be "cat file_$x >> file_$y". Change the 4th line to read "rm file_$x". This should fix your problems.
