Suppose in a directory there are two files 

file1.jpg 
file 2.jpg

Here's my code to loop through the file:

for i in $dir/*
do 
   type=`exiftime -tg $i | cut -c-5`
done

The issue I have is when the loop looks at "file 2.jpg", it treats it as two files because of the space, "file" and "2.jpg". How do I get it to treat the file as one file?

    Always *Quote* your variables to prevent *word-splitting* (e.g. `"$i"`). Yes, quotes *are* permitted (and necessary) within *command substitution* (e.g. `$(....)` or the same with *backticks*) – David C. Rankin Jan 28 '16 at 04:23

Enclose $i in double quotes: "$i"

  • Quote `$dir` too; `for i in "$dir"/*`. You cannot quote the asterisk because that will inhibit wildcard expansion. – tripleee Jan 28 '16 at 04:27
  • Thanks for the help. I have another question, when I run exiftime -tg | cut -c-10 on an invalid pictures, it returns the entire message instead of just the first ten characters. Why does the cut not work here? – user116064 Jan 28 '16 at 04:34
