I am trying to write a password cracker for cracking password locked pdf. I have 4 for loops too iterate through all the possible 4 char passwords. I have a command that gives out error messages if the password is wrong. presently i redirect the error and output to a temporary file and delete the file after every check. This consumes a lot of time and is making the script slower. If anyone could suggest me a better idea or redirection that would be helpful.
我正在尝试编写密码破解程序来破解密码锁定的pdf。我有4个for循环也遍历所有可能的4个char密码。如果密码错误,我有一个命令可以发出错误消息。目前我将错误重定向并输出到临时文件,并在每次检查后删除该文件。这会消耗大量时间并使脚本变慢。如果有人可以建议我一个更好的主意或重定向,这将是有帮助的。
Thanks in Advance Harsha

You can do like this:
你可以这样做:
command > /dev/null 2>&1
To redirect stdout and stderr to /dev/null thus discarding the standard output and standard error completely.
将stdout和stderr重定向到/ dev / null,从而完全丢弃标准输出和标准错误。
