Hi Pengo
If you want the  Number of Cores:  message and the number to appear on the same line, you can do this:

Code: [Select]

echo Number of Cores: `cat /proc/cpuinfo |grep processor |wc -l`The  `  is a back tick, not a single quote. It is usually found on the  ~  key. There is one before  cat  and one after  wc -l.

or that:

Code: [Select]

echo -n Number of Cores:
cat /proc/cpuinfo |grep processor |wc -lThis version suppresses the linefeed from the  echo  command. You can add a trailing space to  Cores:  to separate it from the number.

hi Pengo,

Cool script.

A new version of the RPi4B2 was released:

Code: [Select]

b03112
4B
1.2
2GB
Sony UK
https://github.com/raspberrypi/documentation/blob/master/hardware/raspberrypi/revision-codes/README.md

and the first line should be:

Code: [Select]

#!/bin/sh
Leaving the ! out means it is just a comment and the bash shell is not loaded by default.

regards
Greg

Hi Greg Erskine

... and the first line should be:

Code: [Select]

#!/bin/sh
Leaving the ! out means it is just a comment and the bash shell is not loaded by default. ...

I missed that, nice catch. I'll fix it for him.

Updated version (including the suggested improvements and addition of the new board, thanks!):
