And signing and generating MD5 and SHA1 for all those is a painful task.
Following script makes it easy - copy all the distributions to a single directory and copy the following script to the same directory as sign.sh and execute it as,
$ sh sign.sh prabath
Here, prabath is the alias of the GPG public key.
The following script will generate ASC,MD5 and SHA1 of all the distributions and will also dump the public key to KEYS file.
You should have installed GPG and configured it before running the script.
#!/bin/sh rm *.asc rm *.md5 rm *.sha1 rm KEYS for f0 in *.zip do echo $f0 asc=".asc" md5=".md5" sha1=".sha1" f1=$f0$asc gpg --armor --output $f1 --detach-sig $f0 f2=$f0$md5 gpg --print-md MD5 $f0 > $f2 f3=$f0$sha1 gpg --print-md SHA1 $f0 > $f3 done gpg --armor --export $1 > KEYS
