Removing Letters from an Integer String

[danhodges99]

Hi all,

I have a variable, on some machines it is '1024', which is fine, but on others it is '1024Mb' etc. I need this variable to simply be '1024', does anyone know how I could ensure this is always the case? Perhaps a command to remove any letters/characters that aren't integers if there is one?

Thanks.

echo '1024Mb' | tr -d -c '[:digit:]'
