我有这个简单的脚本:
#!/bin/bash
SOURCE_USER=$USER
DESTINE_USER=$1
id -u $SOURCE_USER > /dev/null 2>&1
if [ "$?" == "1" ] || [ -z $SOURCE_USER ]
then
printf "Error: Invalid source user '$SOURCE_USER'\\n"
exit 1
fi
if [ -z $DESTINE_USER ]
then
printf "Error: Invalid destine user '$DESTINE_USER'\\n"
exit 1
fi
SOURCE_GROUPS=$(id -Gn ${SOURCE_USER} | sed "s/${SOURCE_USER} //g" | sed "s/ ${SOURCE_USER}//g" | sed "s/ /,/g")
SOURCE_SHELL=$(awk -F : -v name=${SOURCE_USER} '(name == $1) { print $7 }' /etc/passwd)
id -u $DESTINE_USER > /dev/null 2>&1
if [ "$?" == "1" ]
then
printf "Creating destine user %s\\n" "$DESTINE_USER"
useradd --groups ${SOURCE_GROUPS} --shell ${SOURCE_SHELL} --create-home ${DESTINE_USER}
passwd ${DESTINE_USER}
xhost '+si:localuser:$DESTINE_USER'
sudo usermod -G "$SOURCE_USER" "$DESTINE_USER"
else
printf "Updating destine user '%s' with groups '%s' and shell '%s'\\n" "$DESTINE_USER" "$SOURCE_GROUPS" "$SOURCE_SHELL"
sudo usermod -a -G "$SOURCE_GROUPS" "$DESTINE_USER"
sudo chsh -s "$SOURCE_SHELL" "$SOURCE_USER"
fi
sudo runuser sublime_vanilla -c "${@:2}"
我像这样运行它:
$ bash run_as_user.sh sublime_vanilla /usr/bin/subl -n "./New Empty File"
但是当我运行它时,我收到了这个错误:
runuser: invalid option -- 'n'
Try 'runuser --help' for more information.
但如果我用sudo runuser sublime_vanilla -c "${@:2}"
取代sudo runuser sublime_vanilla -c "\"$2\" \"$3\" \"$4\" \"$5\" \"$6\" \"$7\" \"$8\" \"${@:9}\""
然后,Sublime Text在新窗口中正确打开文件"./New Empty File"
。
如何使runuser
正确理解所有参数与可变数量的命令行参数,即没有硬编码"\"$2\" \"$3\" \"$4\" ..."
?
这与your last question略有不同,因为您必须将参数扩展为-c选项的单个字符串。
bash printf formatter %q是你的朋友:
cmd=$( printf '%q ' "${@:2}" )
sudo runuser sublime_vanilla -c "$cmd"
另一方面,通过runuser手册页快速浏览表明:
sudo runuser -u sublime_vanilla "${@:2}"
另一个想法:sudo runuser -u sublime_vanilla -- "${@:2}"
用双连字符表示runuser选项的结束。
