Linux 如何以不同的用户身份运行bash命令？

我以root用户身份登录，但是，我正在尝试使用另一个名为marshall的用户从bash脚本运行java程序。我得到以下错误不确定我做错了什么

#!/bin/bash
sudo su marshell <<'EOF'
CP=/home/marshell/sanity_test_scripts/ # The classpath to use
java -cp $CP JavaRunCommand $1 $2 $3 $4 $5 $6 $7 $8 $9 ${10}
EOF

---

为什么不使用su-like的命令标志

-c

>foo=bar；苏马歇尔-c.“/suc$foo”
条形码

脚本只打印传递给它的所有参数。
在您的特定情况下，它应该看起来像

>su marshall-c“CP=/home/marshall/sanity_test_scripts/；java-CP$CP JavaRunCommand$1$2$3$4$5$6$7$8$9${10}”

或

>sudo-u marshell-i“CP=/home/marshell/sanity_test_scripts/；java-CP$CP JavaRunCommand$1$2$3$4$5$6$7$8$9${10}”

对于sudo，您可以使用类似参数
-u
和
-i
的内容

-u user     The -u (user) option causes sudo to run the specified
               command as a user other than root.  To specify a uid
               instead of a user name, use #uid.  When running commands as
               a uid, many shells require that the '#' be escaped with a
               backslash ('\').  Security policies may restrict uids to
               those listed in the password database.  The sudoers policy
               allows uids that are not in the password database as long
               as the targetpw option is not set.  Other security policies
               may not support this.

-i [command]   The -i (simulate initial login) option runs the shell
               specified by the password database entry of the target user
               as a login shell.  This means that login-specific resource
               files such as .profile or .login will be read by the shell.
               If a command is specified, it is passed to the shell for
               execution via the shell's -c option.  If no command is
               specified, an interactive shell is executed.  sudo attempts
               to change to that user's home directory before running the
               shell.  The security policy shall initialize the
               environment to a minimal set of variables, similar to what
               is present when a user logs in.  The Command Environment
               section in the sudoers(5) manual documents how the -i
               option affects the environment in which a command is run
               when the sudoers policy is in use.

你需要逐字逐句地引用应该传递的部分。如果命令行参数是
foo
、
bar
、
baz
和
qux
，并且希望Java执行

java -cp "$CP" JavaRunCommand foo bar baz quux

然后，您需要插入命令行参数，但要引用（美元登录）
$CP
，因此当前shell不会插入它

#!/bin/bash
sudo su marshell <<EOF
CP=/home/marshell/sanity_test_scripts/ # The classpath to use
java -cp "\$CP" JavaRunCommand $@
EOF

虽然我找不到实际错误，但如果需要展开位置参数，则不能引用
EOF
。无论如何，这是一个更好的方法：
java-cp$cp JavaRunCommand“$@”
并且不要忘记在您的情况下取消引用
EOF
：
sudo su marshall如果您已经以root用户身份登录，为什么要使用
sudo
？runbash_marshall.sh：第5行：警告：此处文档位于第2行，由文件结尾分隔（通缉'EOF'）） ................ bash:line 3:EOF:command not found@j.a.我确实按照建议更新了我的代码，它确实起了作用，但我仍然看到上面的警告，不知道为什么？为什么要使用
sudo su
而不是
sudo-u
？我在问题中添加了更新后的脚本
java -cp "$CP" JavaRunCommand foo bar baz quux

#!/bin/bash
sudo su marshell <<EOF
CP=/home/marshell/sanity_test_scripts/ # The classpath to use
java -cp "\$CP" JavaRunCommand $@
EOF

sudo -u marshell java -cp /home/marshell/sanity_test_scripts/ JavaRunCommand "$@"
