I want to do formatting using echo in shell scripting.
Here is a small code snippet which is giving me the problem:
echo -en "\rFileName : $filename : $index of $lines Completed"
The $filename
is a string with varying length, and this is causing problem with formatting in the terminal. How can I overcome this?
Here's what I mean:
FileName : a800_102 : 6 of 6 Completed
FileName : ersf_1024 : 56 of 56 Completed
I would like to have a table format when I display it on the terminal.
Use printf:
printf "\rFileName : %20s : %8d of %8d Completed" $filename $index $lines
