Use the following command in a terminal:
$ cat /proc/version
The information about the CPU is stored in /proc/cpuinfo. The following command will show you the number of processors by reading that file:
$ grep processor /proc/cpuinfo | wc -l
$ grep -c processor /proc/cpuinfo
should also be enough!
There may be occasions when you may need to split a huge file into smaller pieces for storage restrictions (or if you plan on sending them piece-by-piece to a friend!):
The following nifty trick (picked up from Commandline-fu) explains how a directory, <dir>, can first be tarred and split into smaller pieces and later rejoined as need arises:
$ tar cf - <dir> | split -b<max_size>M - <name>.tar.
Rejoin later with `cat’ and then extact:$ cat .tar.* |tar xf -
UPDATE: Problems with the first line of the code is fixed. This arose in the first place because when I put <dir> in the raw HTML box, it just ignored it since <dir> is not a valid HTML tag (as if I wanted it to be!).
