== Serial Number ==

Simple Awk:
cat /proc/cpuinfo | grep Serial | awk '{print $3}'

Bash:
<pre>
cat /proc/cpuinfo | perl -n -e '/^Serial[ ]*: ([0-9a-f]{16})$/ && print "$1\n"'
grep -Po '^Serial\s*:\s*\K[[:xdigit:]]{16}' /proc/cpuinfo
</pre>

Pure Bash:
<pre>
pattern='^Serial.*([[:xdigit:]]{16})$'
while read -r line
do
if [[ $line =~ $pattern ]]
then
echo "${BASH_REMATCH[1]}"
fi
done < /proc/cpuinfo
</pre>

Bash Awk:
awk '/^Serial\s*:\s/{print $3}' /proc/cpuinfo

Python:
<pre>
def getserial():
# Extract serial from cpuinfo file
cpuserial = "0000000000000000"
try:
f = open('/proc/cpuinfo','r')
for line in f:
if line[0:6]=='Serial':
cpuserial = line[10:26]
f.close()
except:
cpuserial = "ERROR000000000"

return cpuserial
</pre>
