Not knowing what your system is, and what options stat offers, this would do the job running stat only once:
Code:
if [  $(( $(stat --printf "%s - " new  old) 0 )) -eq 0 ]; then echo "equal"; else echo "NOT equal"; fi

NAME
sysctl.d - Configure kernel parameters at boot SYNOPSIS
/etc/sysctl.d/*.conf /run/sysctl.d/*.conf /usr/lib/sysctl.d/*.conf DESCRIPTION
systemd uses configuration files from the above directories to configure sysctl(8) kernel parameters to load during boot. CONFIGURATION FORMAT
The configuration files should simply contain a list of variable assignments, separated by newlines. Empty lines and lines whose first non-whitespace character is # or ; are ignored. Note that both / and . are accepted as separators in sysctl variable names. Each configuration file is named in the style of <program>.conf. Files in /etc/ overwrite files with the same name in /usr/lib/. Files in /run overwrite files with the same name in /etc/ and /usr/lib/. Packages should install their configuration files in /usr/lib/, files in /etc/ are reserved for the local administration, which possibly decides to overwrite the configurations installed from packages. All files are sorted by filename in alphabetical order, regardless in which of the directories they reside, to ensure that a specific configuration file takes precedence over another file with an alphabetically later name. EXAMPLE
Example 1. /etc/sysctl.d/domain-name.conf example: # Set kernel YP domain name kernel.domainname=example.com SEE ALSO
