Let's say I've got a list with file names in it with date. I want to do something on files with extension png or jpg of a specific date. I've got the following code:
year="2015"
for f in $myFiles
do
if [[ $f = *"$year"{".png",".jpg"} ]]
then
echo $f
fi
done
This doesn't seem to work, no file passes the condition. I could do it by using two conditions, and using an or condition; but I was wondering what I am doing wrong. Brace expansion should work, otherwise how should I use it.
{...} doesn't expand for if condition. You can use extglob:
shopt -s extglob
[[ $f = *"$year".@(png|jpg) ]] && echo "$f"
You may not even need a for loop with extglob, you can just do:
printf "%s\n" *"$year".@(png|jpg)
