Re: [dev] sbase installed first impressions

I am not too fluent at advanced shell at the moment so help me out
with this one please, I checked the advanced scripting guide but want
to make sure i understand this.

s() { ls -F "$_AT_" | cols; }
s() implies that you have created an alias for ls as "s" and the () is
to listen for what follows for the flags "-h etc"?
{} is to encapsulate the real commands,
ls -F "$_AT_" the "$@" is to pass along the flags from s()?
and for the ; at the end of cols, i assume this terminates in a way
that prevents it from grabbing further input?

Its defaulted to /usr/local, the programs are supposed to be in /bin
/sbin and /usr/(bin, sbin) respectively per standard unix correct? Or
was this intended so to work with stali?

I agree, and even though its an inconvenience i was happy to see this
done since cols can add this output format as desired making the rest
just scripts and such.

Yea, its by no means a deal breaker. It boils down to convenience once
again and the ability to at a glance see the folder, link, file status
without a second command or list view. If anything i'm surprised there
isn't a program for it but i guess the old school way was with list
:-p i'm sure i will suck it up and work around it.

Honestly i never use -i and get annoyed when its on by default. I
can't off hand think of a good use case other than keeping less
experienced people from wiping a system but isnt " rm -rf * " half the
fun of learning unix? *insert evil grin*
