Scripting

[Nobody's Hero]

I have a question that is not that important.
Sometimes when you run an HP script like Q4 for example. you see the dotted lines running accross the page until the procedure finishes.

like '................................................... processing completed.'

Does anyone know how this is scripted? I can echo a line of 'dots'. but I can not get them to proceed one after another. Like I said , not real important, its just bugging me because I can't figure out how to do it.

TIA,

B.

Or like the rotating slash. I always liked that. Anyone know how to do that?

Hi,

Lots of scripts do it like this:

echo ".\c"

The \c tells 'echo' not to append a new-line character at the end of the line. Put that in a loop and you have your dots.

Isn't Q$ perl based?

#!/opt/bin/perl

$| = 1;
@mark = qw{ / | \ - };
$i = 100;
while ($i--) {
print $mark[$i % 4], "\r";
for (1..0x5ffff) { 1 } # delay
}

Hi,

you could do something like

echo "^H|\c"; sleep 1; echo "^H/\c"; sleep 1 ; echo "^H-\c" and so on.

Put this in a extra script in a loop an run it in the background.

This should give you the rotating slash.

Hope this helps

Regards Stefan

Here's a shell script to do the rotating /...

#!/bin/sh

CHAR[0]="|"
CHAR[1]="/"
CHAR[2]="-"
CHAR[3]="\\"

let I=0
print -n " "

while true
do
let N=I%4
let I=I+1
print -n "\010${CHAR[N]}"
sleep 1
done

Hi,

And here is a 'launcher' ...

A - sh script called rotate.sh :

#!/usr/bin/sh
while :
do
echo '\\'"\r\c"
sleep 1
echo "|\r\c"
sleep 1
echo "/\r\c"
sleep 1
echo "-\r\c"
sleep 1
done

B - sh script 'go.sh' :

#!/usr/bin/sh
trap 'kill $I ; exit $R' 0 1 2 3 15
rotate.sh &
I=$!
$*
R=$?

C - try it for example using :

go.sh du -ks /usr

Regards.

Nice one Jimmy!

You could have at least have taken the trouble to change some of the variable names.

John,

Imitation is the sincerest form of flattery. Besides, with the timestamp bug on the forum, how do we know you were really first? :)

I was. But obviously Robert does not like perl :/
