I almost always use them. Only left them out for very simple scripts. It's not really necessary all the time, but better safe than sorry... On Jan 9, 2017 22:00, "Bob Jonkman via talk" <talk@gtalug.org> wrote: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Chris F.A. Johnson wrote:

Are braced incorrect here? I've been putting braces around all variable names, so that there are fewer syntax exceptions for me to remember... - --Bob. On 2017-01-09 05:47 PM, Chris F.A. Johnson via talk wrote:

Using brackets you can mix variables and text and create something like this: newName="${oldname}-bkp-${filedate}.${extension}.old"
The braces are not necessary here. This will work fine:
newName="$oldname-bkp-$filedate.$extension.old"
Braces would be necessary if you were using underscores instead of hyphens because they can be part of a variable name:
newName="${oldname}_bkp_$filedate.$extension.old"
