This is a simple bash file:

this_year="$(date +%Y)"
wget -Ec "https://nvd.nist.gov/feeds/json/cve/1.1/nvdcve-1.1-{modified,recent,{$this_year..2002}}.json.gz" -P gz

I’m going to download all files which names are modified, recent, and from $this_year to 2002.

The current code has this error:

root@server:~/tmp# this_year="$(date +%Y)"
wget -Ec "https://nvd.nist.gov/feeds/json/cve/1.1/nvdcve-1.1-{modified,recent,{$this_year..2002}}.json.gz" -P gz

I tried to do it in a for loop:

root@server:~/tmp# for i in {$this_year..2002}; do echo this is $i; done
this is {2024..2002}
root@server:~/tmp# for i in {$this_year..2002}; do https://nvd.nist.gov/feeds/json/cve/1.1/nvdcve-1.1-$i.json.gz; done
-bash: https://nvd.nist.gov/feeds/json/cve/1.1/nvdcve-1.1-{2024..2002}.json.gz: No such file or directory

How can I download based on this pattern?
