我试图编写一个备份脚本，将排除超过一定大小的文件。
我的脚本给出了正确的命令，但在脚本中运行时，它会输出一个错误。 但是，如果相同的命令手动运行，一切正常…？
这是基于一个简单的谷歌find的脚本
#!/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="7743E14E" # 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= 如果运行，我收到错误;
Command line error: Expected 2 args, got 6 Enter 'duplicity --help' for help screen.
任何帮助你可以提供将不胜感激。
我解决了这个问题
