[SOLVED] How would I list files which only have a specific amount of characters?

Issue

If I have these files:

• a.txt (50 characters)
• b.txt (21 characters)
• c.txt (46 characters)
• d.txt (10 characters)
• e.txt (21 characters)

What command can I use in the command line to only find files with a character count of exactly 21? In this case the command would return something like:
b.txt e.txt

Solution

Here's one approach ...

stat -c "%s %n" *txt | awk '$1=="21"{print $2}'
b.txt
e.txt
