To generate a one time password, I would do in Bash:
oathtool -b --totp `gpg -d secret.gpg`
How do I do the equivalent in Eshell?
I tried:
oathtool -b --totp ${gpg -d secret.gpg}
But that doesn’t work. Even the following doesn’t work:
echo ${gpg -h}
I expect GnuPG’s help text, but there’s no output.
