If you want to use GnuPG in a script and don’t want to be prompted for the passphrase, put the passphrase in a file called passphrase.txt<\/code> and use this to encrypt: <\/p>\n

\r\ngpg --passphrase-fd 3 -c 3< passphrase.txt < filename > filename.gpg\r\n<\/pre>\n
Of course, you can also use echo to specify your passphrase<\/p>\n
\r\ngpg --passphrase-fd 3 -c 3< <(echo "secret") < filename > filename.gpg\r\n<\/pre>\n
or you can pipe a tarball into gpg<\/p>\n
\r\ntar -cf - dir\/ | gpg --passphrase-fd 3 -c 3< <(echo "pass") > backup.tar.gpg\r\n<\/pre>\n
or even send a gpg encrypted tarball via e-mail<\/p>\n
\r\ntar c dir\/ | gpg --force-mdc -ac -o - --passphrase-fd 3 -c 3< <(echo "pass") | mail user@domain.tld\r\n<\/pre>\n
Note that you have to use the --batch<\/code> flag if you want to run gpg from a cron script. (Otherwise gpg tries to read from \/dev\/tty that doesn’t exist for cron jobs)1<\/SUP><\/A>.<\/p>\n
