Hi!,

My script generates a lot of files while running.. The same output at any point may be diercted to some of them..

if I have 4 files file1 file2 file3 file4,

echo "output" to file1 file2 file3 file4

Any ideas on how to do it??

Try the tee(1) command.

e.g. echo "ABCD" | tee file1 file2 file3

Look into the 'tee' command. You can use it to duplicate output between both standard output and a file. The -a option opens the file for appending, which is what I think you want. For example:

echo "some text" | tee -a file1 file2 file3

There's probably some trick you can also do with shell file descriptors, but I'm not familiar enough with those techniques.
