url = https://website.com/download/media/123
This would maybe return a file called file.zip or maybe not. So I want to check if the file which gets downloaded ends with .zip
Maybe something like this?
wget $url -P ~/downloads
if [ downloaded file ends with .zip ]
then:
unzip file.zip
else
echo "Downloaded file doesn't end with zip!"
fi
#!/bin/sh
for a in *
do
zip=$(printf "${a}" | tail -c 3 | grep -o "zip")
[ -n "${zip}" ] && unzip "${a}"
[ -z "${zip}" ] && echo "File ${a} doesn't end with zip!"
done
Simplifying the idea of get extension and add check via file utility:
for a in *
do
zip="${a##*.}"
zip2=$(file $a|grep "Zip archive data"|wc -l)
if [ "zip" = "${zip}" ] || [ "$zip2" -gt 0 ]
then unzip "${a}"
else echo "File ${a} is not zip archive"
fi
done
