Bash script to execute command with file from directory and condition

Question

I'd like to sort my figlet fonts with testing, so I've decided to make a script, which will demonstrate figlet font one by one and will delete fonts I don't like. I've tried to find the solution for correct if-then condition inside while loop, but couldn't find one. Here's the script itself, but for now it just provides examples of all the fonts in the single scroll:

#!/bin/bash #script to test figlet fonts rm /usr/share/figlet/list.txt #delete old list ls /usr/share/figlet > /usr/share/figlet/list.txt #create new list filename='/usr/share/figlet/list.txt' n=1 while read line; do figlet -f $line Figlet echo -e "Press 0 if you don't like it, font will be deleted" read decision if [ "$decision" = "0" ]; then rm "/usr/share/figlet/$line" echo -e "Font deleted" else echo -e "Font saved" fi n=$((n+1)) done < $filename 

Answer 1

The original problem, is that content of your file list is being fed to read decision and while cycle doesn't work as you expect. Though why do you need a list at all?

Better to iterate through files with for cycle.

#!/bin/bash for font in /usr/share/figlet/*; do figlet -f "$font" Figlet echo -e "Press 0 if you don't like it, font will be deleted" read decision if [ "$decision" = "0" ]; then rm "$font" echo -e "Font deleted" else echo -e "Font saved" fi done
