shell腳本決議器錯誤雙引號關閉，即使關閉-有解無憂

#!/data/data/com.termux/files/usr/bin/bash
basedir=$(dirname "$0")

#unset LD_PRELOAD in case termux-exec is installed. If termux-exec is also installed inside the jail it will set again.
unset LD_PRELOAD

command="proot"
command =" -r $basedir/termux-fs"
command =" -b /system"
command =" -b /dev/"
command =" -b /sys/"
command =" -b /etc/"
command =" -b /proc/"
command =" -b /vendor"
command =" -b /data/dalvik-cache/"
command =" -b /property_contexts"
if [ -n "$(ls -A "$basedir"/binds)" ]; then
    for f in $basedir/binds/* ;do
        . "$f"
    done

command =" PREFIX=/data/data/com.termux/files/usr"
command =" TMPDIR=/data/data/com.termux/files/usr/tmp"
com="$@"

if [ -z "$com" ];then
    eval "exec $command login"
else
    eval "exec $command login -c "$com""
fi

錯誤


./start.sh: line 39: unexpected EOF while looking for matching `"'
./start.sh: line 41: syntax error: unexpected end of file

每個雙引號都關閉了為什么它不斷拋出錯誤嘗試通過 sh 而不是 bash 但仍然錯誤

它還在 command =" -b /system" 上顯示關于關閉雙引號的錯誤誰能解釋一下？

你不需要eval. 使用陣列來存盤命令的引數。

#!/data/data/com.termux/files/usr/bin/bash
basedir=$(dirname "$0")

#unset LD_PRELOAD in case termux-exec is installed. If termux-exec is also installed inside the jail it will set again.
unset LD_PRELOAD

command="proot"
command_args=( 
  -r "$basedir/termux-fs"
  -b /system
  # etc
)

command_args =(-b /property_contexts)

shopt -s nullglob
for f in "$basedir"/binds/*; do . "$f"; done

command_args =(
  -w /data/data/com.termux/files/home/
  /data/data/com.termux/files/usr/bin/env -i
  HOME=/data/data/com.termux/files/home  
  PATH=/data/data/com.termux/files/usr/bin:/data/data/com.termux/files/usr/bin/applets
  "TERM=$TERM"
  # etc
  login
)
    
if (( $# == 0 )); then
  command_args =( -c "$@" )
fi

exec "$command" "${command_args[@]}"

重新檢查字串：

eval "exec $command login -c "$com""

你必須在 shell 中轉義雙引號。
