Hi all,
I am newbie and Im trying to rename a set of files & there are over 2900 of them. So, the best way I thought was through a script and here is what I got & it doesnt work.
Im not sure as how to figure this out.
Thanks
Gonzalez
Here is what I have -
I cant seem to put the above line into a script and when I did, it errors out. Here is what I have in the script.

When I run the above script, it gives me this error -
That's a useless use of ls *. Whenever you have `ls *` you could just write * and get the same result.
When you have thousands of files, though? You could easily hit the argument size limit trying to use shell globbing, better to use find and read filenames line by line.
What does File_New=echo do? Set the variable "File_new" to the string "echo". Then tries to run the command "$file", which probably becomes "". I don't think that's what you intended.
Also, why run awk 4000 times instead of once?
Also, are you intending to rename files to the current time, or their own time?
File_new has no $ here. So you're trying to move the literal file file_new into whatever $file is.
What's your system? What's your shell? What you can write depends on that.
As you can see, I have a file name like this ABCD_201103027_11fh & Im trying to make it as ABCD_201103027_195051_Log.txt ie.,
Input - ABCD_201103027_11fh
output - ABCD_201103027_195051_Log.txt
as there are very many files like above, Im trying to rename all of the 2900 of them to stick to the format of ABCD_201103027_timestamp_Log.txt so that each file has a unique name & also a timestamp. Now, to achieve that unique name, Im using the sleep 1 to wait for the next second so that in the next iteration, the file would be named differently.
Now, having said all of the above lines, it could be a totally useless script as you mentioned but can you make it to work ?
Im also open to any other way of doing this but I just cant seem to get that idea nor make this script work.
Hope I made it a clear enough. Any & all help is appreciated with gratitude.

Ahah -- so the timestamp isn't to mark it with its own time, but to make the filename unique! Okay.

But since you can't or won't say, I'll try to write a solution that'll work even in terrible shells. Unfortunately that means it won't be the fastest or most efficient or most direct way I could write it.
