scripts: Fix arguments
Change handling of arguments in `scripts/generate-hashsums`.
Note that even before the script would have not worked for more than one
argument. Therefore, it is best to change this to a single-argument
script.
#!/bin/sh
echo -n "- name: "
-basename "$*"
+basename "$1"
echo -n "- size: "
-ls -l "$*" | cut -f 5 -d " "
+ls -l "$1" | cut -f 5 -d " "
echo -n "- md5sum: "
-md5sum "$*" | cut -f 1 -d " "
+md5sum "$1" | cut -f 1 -d " "
echo -n "- sha1: "
-sha1sum "$*" | cut -f 1 -d " "
+sha1sum "$1" | cut -f 1 -d " "
echo -n "- sha256: "
-sha256sum "$*" | cut -f 1 -d " " | head -c -1
+sha256sum "$1" | cut -f 1 -d " " | head -c -1
