在所編寫的腳本文件中,使用 echo "passwd" | sudo -S command
使用-S是:使得sudo從標準輸入讀取密碼而非終端
sudo的命令選項:
Options:
-A, --askpass use a helper program for password prompting
-b, --background run command in the background
-C, --close-from=num close all file descriptors >= num
-E, --preserve-env preserve user environment when running command
-e, --edit edit files instead of running a command
-g, --group=group run command as the specified group name or ID
-H, --set-home set HOME variable to target user's home dir
-h, --help display help message and exit
-h, --host=host run command on host (if supported by plugin)
-i, --login run login shell as the target user; a command may also be specified
-K, --remove-timestamp remove timestamp file completely
-k, --reset-timestamp invalidate timestamp file
-l, --list list user's privileges or check a specific command; use twice for longer format
-n, --non-interactive non-interactive mode, no prompts are used
-P, --preserve-groups preserve group vector instead of setting to target's
-p, --prompt=prompt use the specified password prompt
-r, --role=role create SELinux security context with specifie role
-S, --stdin read password from standard input
-s, --shell run shell as the target user; a command may also be specified
-t, --type=type create SELinux security context with specified type
-U, --other-user=user in list mode, display privileges for user
-u, --user=user run command (or edit file) as specified user name or ID
-V, --version display version information and exit
-v, --validate update user's timestamp without running a command
-- stop processing command line arguments
例如:
使用sudo在shell文件中調用其他的腳本
echo "123456" | sudo -S ./crack_rvct.sh
又比如使用腳本進行關機命令:
#!/bin/bash
echo "passwd" | sudo -S shutdown -P now
以上就是解決從腳本中輸入sudo密碼的方法。
