script sh : command wait an input from keyboard, but script type the input
我有一个需要从键盘输入的命令，不能直接从命令行获得它，就像sudo一样，我忘记了将一个已知变量传递给终端输入的语法：[sudo] password for cl-r：'
#/bin/bash (or ksh)
.....
VARIABLE_NEEDED=$1
mycommand_wait_and_needs_input_from_keyboard [?? magic-instruction_beginning ??] # command prompt for input
VARIABLE_NEEDED
[?? magic-instruction_end ??]
# ... command executed
[ $? != 0 ] && ...
也许你的意思是：
echo -n "$VARIABLE_NEEDED" | mycommand_wait_and_needs_input_from_keyboard
Take a look at line 7 of my dotfiles. You can invoke sudo -v in a bash script to run it with sudo permissions.
