If you get a result from
cat /proc/cpuinfo | grep " lm "
you're on a 64-bit processor regardless whether it's a 32- or 64-bit OS.
If you want to know if the OS is 64-bit, then a result from
uname -a | grep 64
would indicate a 64-bit OS.
Stupid shell script:
#!/bin/bash
echo -n "Running "
RES=`uname -a | grep 64`
if [ $? -eq 0 ]; then
echo -n "64-bit "
else
echo -n "32-bit "
fi
echo -n "operating system on a "
RES=`cat /proc/cpuinfo | grep " lm "`
if [ $? -eq 0 ]; then
echo -n "64-bit "
else
echo -n "32-bit "
fi
echo "machine"
Have fun, gang.
