If you know in advance the number of rows & colums, it's easy:
term% cat t
one two three four
five six seven eight
nine ten eleven twelve
term% tr -s ' ' '\xA'
hi,
i rustled up a small limbo program (attached) that does the trick.
hope this helps.
% cat num1.txt
one two three
four five six
seven eight nine
% ./trans num1.txt
one four seven
two five eight
three six nine
% cat num2.txt
one two three four
five six

with a more complex type system that you cannot express in go. A
good, simple example is "map". Go would need generics to support it.
$GOOROOT/src/pkg/bytes/bytes.go:248 func ToLower(s []byte) []byte
{ return Map(unicode.ToLower, s) }
I should have been more clear. I mean a generic map of
Hi,
I'm new to plan9 from user space. I've started using rc shell for
scripts and, for daily use, I would like to solve a problem.
I see that rc isn't built with readline or similar. So, do you use
some alternative? Or do you think I can live without it?
Thanks,
Maurício
what i find i can't live without is a record
of the commands i've typed. sometimes a
one-liner from last week is useful. i use the
commands - and -- (source: /n/sources/contrib/quanstro/src/history.c)
along with the following patch to rc to make it
go.

For scripting it shouldn't be an issue.

correct me if i am wrong. but isn't the usual MIPS calling convention to
store the return pc in R31?
you may just want to look at your compiler output. mips has various
"branch and link" commands that do a branch and put the returning pc
into R31, which is the usual calling convention.

The other (Byron Rakitzis) unix port of rc can be linked against
either readline or editline.

fortunately, in unix you can run go :).

Would this answer your question:
http://blogs.sun.com/jonh/entry/the_dtrace_deadman_mechanism
Well, it answers the question "What is the DTrace so-called deadman
mechanism?" I think.
That's a sort of part of a possible solution, which is OK.
To be pedantic, it's not a true deadman mechanism
Wow.
Excellent us of tools.
The smallest arbitrary-columns answer I could come up with was:
awk '{if(m < NF)m=NF;for(i=1;i<=NF;i++)r[NR, i]=$i}END {for(i=1;i<=m;i+
+){for(j=1;j<=NR;j++)printf "%s ", r[j,i];print ""}}' t
I'm sure there's an insane sed solution out there somewhere for very

If Richard's trick won't work, grab contrib/lyndon/transpose.c.
It's dog slow (actually, avl(2) is), but its effectively
unbounded for the input dataset size.
