Script to concatenate several files
I need a script to concatenate several files in one step, I have 3 header files say file.S, file.X and file.R, I need to concatenate these 3 header files to data files, say file1.S, file1.R, file1.X so that the header file "file.S" will be concatenated to all data files with .S extentions and so on for "file.X" and file.R with the .X and .R data files..
I tried using wild cards, like: cat file.S file[1-50].S > file[1-50].SP but I got a message saying that file[1-50].SP does not match so can this be done through a script? this will save a LOT of time for me, so if someone can help me it will be much appreciated

If I understand your question this should work (not tested!):
Code:
for letter in S R X
do
for i in file[0-9].$letter
do
cat file.$letter > "$i"P
cat "$i" >> "$i"P
done
done

These are basic shell loops, you should read some books or tutorials about scripting. To learn scripting is to read about it and try to find things out yourself.
Echo the variables within the loop like: Code:
for letter in S R X
do
for i in file[0-9].$letter
do
echo file
echo $letter
echo file.$letter
echo "$i"P
echo "$i"
done
done
Here you can read something about loops and variables (Googled on 'ksh scripting tutorial'): KSH script BASICS Regards
