我想使用openssl加密文件.我可以通过使用来做到这一点
openssl des3 -salt -in /pritom/uaeyha_com.sql -out /pritom/a.ss
当我运行此命令时,它会从我那里获取密码两次.我想用脚本设置密码,我用过
openssl des3 -salt -in /pritom/uaeyha_com.sql -out /pritom/a.ss -pass pritom
但它给了我以下错误:
Invalid password argument "pritom"
Error getting password
我现在能做什么？

假设我的文件a.conf如下
Include /1
Include /2
Include /3
我想用新行替换"Include/2",我在.sh文件中编写代码:
line="Include /2"
rep=""
sed -e "s/${line}/${rep}/g" /root/new_scripts/a.conf

我创建了一个facebook应用程序.这对我来说可以.但我的问题是始终显示垂直和水平滚动条,当我从Facebook设置使用流体的页面的宽度和高度.我的页面看起来像这个http://karen.webmascot.com/fb/fbone.jpg.我现在能做什么？
我在.sh文件中编写代码并运行它...
