linux - Adding timestamp to a filename with mv in BASH

Question

Well, I'm a linux newbie, and I'm having an issue with a simple bash script.

I've got a program that adds to a log file while it's running. Over time that log file gets huge. I'd like to create a startup script which will rename and move the log file before each run, effectively creating separate log files for each run of the program. Here's what I've got so far:

pastebin

DATE=$(date +"%Y%m%d%H%M")
mv server.log logs/$DATE.log
echo program

When run, I see this:

: command not found
program

When I cd to the logs directory and run dir, I see this:

201111211437
.log

What's going on? I'm assuming there's some syntax issue I'm missing, but I can't seem to figure it out.

UPDATE: Thanks to shellter's comment below, I've found the problem to be due to the fact that I'm editing the .sh file in Notepad++ in windows, and then sending via ftp to the server, where I run the file via ssh. After running dos2unix on the file, it works.

New question: How can I save the file correctly in the first place, to avoid having to perform this fix every time I resend the file?

Answer 1

mv server.log logs/$(date -d "today" +"%Y%m%d%H%M").log
