Raspberry Pi - Data Logging and Databases

This script is intended to rotate logs daily but fails:

logfile="/var/log/syslog"
cp $logfile $logfile.1
> $logfile

What is the likely problem?

Acp command cannot copy files in /var/log

BThe > operator should be >> to append, not overwrite

CNot using quotes around $logfile can cause issues if path has spaces

DMissing sudo causes permission denied error

Step-by-Step Solution

Solution:

Step 1: Analyze variable usage in cp and redirection
Without quotes, if logfile path contains spaces, commands may fail or behave unexpectedly.
Step 2: Check other options
Using > to clear logfile is correct; cp works on /var/log if permissions allow; sudo may be needed but not guaranteed cause here.
Final Answer:
Not using quotes around $logfile can cause issues if path has spaces -> Option C
Quick Check:
Quote file paths to avoid errors [OK]

Quick Trick: Quote file paths in scripts to prevent errors [OK]
