我正在尝试编写一个备份脚本来排除超过一定大小的文件。
如果我运行脚本,duplicity 会出现错误。但是,如果我复制并粘贴脚本生成的相同命令,一切正常...
以下是脚本
#!/bin/bash
# Export some ENV variables so you don't have to type anything
export AWS_ACCESS_KEY_ID="accesskey"
export AWS_SECRET_ACCESS_KEY="secretaccesskey"
export PASSPHRASE="password"
SOURCE=/home/
DEST=s3+http://s3bucket
GPG_KEY="gpgkey"
# exclude files over 100MB
exclude ()
{
find /home/jason -size +100M \
| while read FILE; do
echo -n " --exclude "
echo -n \'**${FILE##/*/}\' | sed 's/\ /\\ /g' #Replace whitespace with "\ "
done
}
echo "Using Command"
echo "duplicity --encrypt-key=$GPG_KEY --sign-key=$GPG_KEY `exclude` $SOURCE $DEST"
duplicity --encrypt-key=$GPG_KEY --sign-key=$GPG_KEY `exclude` $SOURCE $DEST
# Reset the ENV variables.
export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=
export PASSPHRASE=
当脚本运行时我收到错误;
Command line error: Expected 2 args, got 6
我哪里错了??

我解决了这个问题..
#!/bin/bash

export PASSPHRASE="password"
SOURCE=/home/
DEST=s3+http://s3bucket
GPG_KEY="gpgkey"
# Generate a filelist of excluded files over 100MB
find $SOURCE -size +100M > /tmp/filelist
duplicity --exclude-filelist /tmp/filelist --encrypt-key=$GPG_KEY --sign-key=$GPG_KEY $SOURCE $DEST
# Reset the ENV variables.
