Re: [Pan-users] 0.11.3 question

You are correct in some cases about the quotes.

However, if the filename contains spaces (or any other non-printable 
character) the quotes would be required. The syntax with the quotes will 
work in all cases, but without the quotes will only work in some cases.

The squiggly braces is the correct syntax for a universal command using 
variable names as well.
   For example, if you have 2 variables   ( b and bb ) then using  $bb 
may not get what you want.  If I wanted to have the contents of $b 
appended with a literal b I could NOT guartantee to do it without the 
use of the squiggly braces.  ${b}b would give the results I wanted, but 
the system may in some cases chose to do that OR instead use the 
contents of bb if I use $bb.  $bb will ALWAYS match $b, then have to 
check again to see if there is another it matches ($bb) However, ${bb} 
will ONLY match  variable bb and NEVER match variable b.

Please read up on the shell special characters before you make a 
blanket statement that "they are not needed".

I have downloaded some music files that have spaces in the name, and 
when I wanted to remove the spaces I had to devise a way to use the 
actual original filename with the looping features of the shell to 
automaticlaly change all filenames in the directory.  The quotes were 
required to do it correctly since the quotes change the space from a 
special delimiter to an actual character.
