Title: Microcore commands
Post by: Colin on June 10, 2015, 05:13:38 AM

I hope I'm not being ignorant & that I won't get an angry response, but is there an easy way of listing all commands available in Microcore so I can > them into command.txt?  I've tried tab tab but they scroll past too fast, & compgen doesn't seem to work.

I don't think there is. "help" will list only busybox executables, otherwise maybe "ls /usr/bin" for all PATH directories?

Do you know you can scroll in a shell by shift-page up?

I often make a quick listing of programs available on new systems, here's how I do it.

Code: [Select]

ls -C /bin /sbin /usr/bin /usr/sbin /usr/local/bin >> progsThis uses the -C option to arrange the output into columns.
(Use less progs to view.)

Sorry for the delay in getting back, but thanks both!
There do seem to be a lot of commands & executables I don't need, is it easy to get rid of them please?
And do you think MC can be stripped down to 999kb or less?
Thanks again

Many of the builtin commands are just symlinks to busybox.

Code: [Select]

ls -l /bin /sbin /usr/bin /usr/sbin /usr/local/bin | grep busybox

/usr/local/bin/mc  is just 972K
mcdiff, mcedit, mcview are the same size though, and seem to actually be just copies of  mc . I wonder if those would work if they where just symlinked to  mc  just like with busybox.


EDIT:
Yep, that works.  mc.tcz  could be repacked using symlinks for  mcdiff, mcedit, mcview .
However, this doesn't reduce the size of  mc.tcz . I guess squashfs is smart enough to detect duplicates.

In case you mean MicroCore, no, just the kernel is 3.3mb. You cannot fit a current kernel to a floppy even in a minimal config, and that is 1.44mb.
