Shell Programming and Scripting

Hi all,
I would like to know how to have graphics embedded using shell scripts...
I mean simple =========>
or ---------> would do...
The main idea here is for every element of the bar to move for every % completion of data.....

I tried echo under a for loop ,but it was not giving me o/p that i could use?

eg:,
lets say that i want to install a pkg, a huge one...now for every % of the installation completed i would like to have "===>" ,move one step ahead....

If this is difficult to incorporate then i woudnt mind having a regular % counting itself (with numericals)

Thanks

If you get number of files to be installed, you can use the following as a starting point

Code:

count=0
while [ $count -le 10 ]; do
      count=`expr $count + 1`
      sleep 1
      echo -n =
done
echo " Done"

I thought of that, but then it is compressed and if i have to find out the no of files in it then i will have to extract then perform the codes youve given..
Which i feel could incur overhead!!!

Could you tell me if its possible to compare the size of the file at the destination against the source then use it as a delimiter?

Thanks

I think you're mixing up two things. When exactly to print another character is probably fairly specific to your particular problem. Assume the screen is 80 characters wide, or use curses or the $COLUMNS environment variable to figure out how wide the user's screen is. Then however you want to calculate the % completion, divide 100% by 80 (or whatever other value you came up with) and print another character when another 1/80 has been completed.

A fairly traditional "pretty" progress bar would use the fact that carriage return will return the cursor to column 1 without advancing to a new line (newline does that). So you can create an illusion of a growing bar by printing "=>\r" then "==>\r" then "===>\r" and so forth. I believe the progress bar example I presented a couple of weeks ago demonstrated this (albeit with numbers instead of ASCII graphics).
