Processing indicator

[scriptfinder]

Hi! Folks!

Can someone help me with a code snippet to indicate processing, while my shell script is doing some work in the background?. The indicator's like continuous printing of forward slash, pipe, and backward slash or any thing else in the same character position.

Thank you very much in advance.

How about something like:
[tt]
while true; do
echo -en "\b/"
sleep 0.2
echo -en "\b-"
sleep 0.2
echo -en "\b\\"
sleep 0.2
echo -en "\b|"
sleep 0.2
done
[/tt]
This works in Debian Linux.

Hi! TonyGroves!

I got the following error.

sleep: bad character in argument

I have SunOs. Any ideas?

Thanks.

Just use sleep 1 instead then.

It seems too slow.. but if there is no way I can break it into fractions of a second, I am okay with one.

thanks again...

check out if you have usleep command

usleep 200000 sleeps for 200000 microseconds or 0.2s


HTH,

A Couple that I've played with in the past

sign=("/" "-" "\\\\" "|"); pozi=0
 echo -n Working...
  while read strinf;do
    echo -en "${sign[$pozi]}\b; let pozi=(pozi+1)%4
  done < inputfile
echo ok

or in perl

$|=1;
print "Please wait...\n";
my @twirl=qw (-\|/);
for (my $counter=1| $counter <5; $counter ++)
 {
  print "\b\b$twirl[$counter %4]";
  sleep 1
 }
 print "Count Done.";

If you need a usleep for an OS which doesn't provide it, but do have a compiler handy, I wrote this C snippet to make the system call (works on Solaris):

#include <unistd.h>
#include <stdio.h>

int main (int argc, char *argv[]) {
        int sleeptime;

        if (argc < 2 || sscanf(argv[1],"%d",&sleeptime) != 1) {
                printf("usage: usleep <microseconds>\n");
                return 1;
        } else {
                return usleep(sleeptime);
        }
}
