我想使用openssl加密文件。我可以用

When I run this command, it gets password from me two times. I want to set password with the script and I used

当我运行这个命令时，它会从我这里获得两次密码。我想用我使用的脚本设置密码

openssl des3 -salt -in /pritom/uaeyha_com.sql -out /pritom/a.ss -pass pritom

but it gives me the following error:

但它给了我以下的错误:

Invalid password argument "pritom"

Try something like this -

试试这个-

openssl des3 -salt -in /pritom/uaeyha_com.sql -out /pritom/a.ss -pass pass:pritom

From the man page:

从手册页:

PASS PHRASE ARGUMENTS Several commands accept password arguments, typically using -passin and -passout for input and output passwords respectively. These allow the password to be obtained from a variety of sources. Both of these options take a single argument whose format is described below. If no password argument is given and a password is required then the user is prompted to enter one: this will typically be read from the current terminal with echoing turned off.

传递短语参数:多个命令接受密码参数，通常分别使用-passin和-passout作为输入和输出密码。这些允许从各种来源获取密码。这两个选项都使用一个参数，其格式如下所示。如果没有给出密码参数，并且需要输入密码，则会提示用户输入一个:这通常是从当前终端读取，并关闭echo。

   pass:password
             the actual password is password. Since the password is visible to utilities (like 'ps' under Unix)
             this form should only be used where security is not important.

   env:var   obtain the password from the environment variable var. Since the environment of other processes is
             visible on certain platforms (e.g. ps under certain Unix OSes) this option should be used with
             caution.

   file:pathname
             the first line of pathname is the password. If the same pathname argument is supplied to -passin and
             -passout arguments then the first line will be used for the input password and the next line for the
             output password. pathname need not refer to a regular file: it could for example refer to a device
             or named pipe.

   fd:number read the password from the file descriptor number. This can be used to send the data via a pipe for
             example.

   stdin     read the password from standard input.

to hide it from the ps command use :

在ps命令中隐藏它:

temp_varX=pritom ;
openssl .....  -pass fd:0 <<< "$temp_var"
