help needed with a small shell script!
I have a scenario where i need to look for files of these kind
Code:
filename.log.0
filename.log.1

if the files are present, then no action is to be taken, if not found,
then it shud create/touch files with the same name.

so can anyone help constructing the script for me..appreciate ur help.

That's an extremely vague description, with no indication of how the script knows which files to check for and create.
Code:
for N in 1 2 3 4 5
do
        [ -f /path/to/log.file.$N ] || touch /path/to/log.file.$N
done

If this doesn't do what you want, explain why.

You said all this already, this is no clearer.

Are they really named "filename.log"? Will they always be the same name? How do you get the name?

Where are they stored?

How many of them? Just 0 and 1? Or are there potentially unlimited numbers?

How would the script know when to stop?

If there are only two filenames:

Code:
for filename in "filename.log.0" "filename.log.1"
do
    if [ ! -f "$[filename}" ]
    then
           touch "${filename}"
   fi
done
