line 1: ?#!/usr/bin/sh: not found when trying to execute a shell script
提问by Don
I have a script called autoinstall:
我有一个名为autoinstall的脚本：
#!/usr/bin/sh
echo "Installasi membutuhkan free space minimal 2MB, pastikan ada punya cukup space di router anda"
read -p "Anda yakin ingin melanjutkan installasi?(y/n) " -n 1 -r
echo ""
if [[ $REPLY = ^[Yy]$ ]]
then
cd /
cd /tmp/
tar -xvf OpenWrt_Angel_Beats_Edition_v1.3.3.tar -C /
chmod -R 744 /root/crt
chmod 744 /www/wget/wget_download.sh
chmod 744 /usr/bin/gsm
chmod 744 /usr/bin/profile
opkg update && opkg install elinks
cp /etc/rc.local /etc/rc.local.backup
cat > /etc/rc.local << END
#!bin/sh
# /etc/rc.local: Local system initialization script.
#
# Put any local startup commands in here. Also, if you have
# anything that needs to be run at shutdown time you can
# make an /etc/rc.d/rc.local_shutdown script and put those
# commands in there.
sh /www/wget/wget_download.sh > /dev/null 2>&1 &
exit 0
END
killall sh /www/wget/wget_download.sh
sh /www/wget/wget_download.sh > /dev/null 2>&1 &
echo "File backup /etc/rc.local.backup telah dibuat, gunakan file ini untuk mengembalikan konfigurasi rc.local anda yang dulu jika diperlukan"
echo "Installasi selesai. Jangan lupa di akun openvpn yang digunakan (/root/crt/xxx.ovpn) tambahkan baris ini:
script-security 2
up client-connect.sh"
else
echo ""
echo "Installasi dibatalkan"
fi
Every command that I put in the first line always gets the error above (line 1:xxx not found) and I'm sure I've typed in the correct command, even echogives the error like that, how do I solve this?
我放在第一行的每个命令总是得到上面的错误 ( line 1:xxx not found) 并且我确定我输入了正确的命令，甚至echo给出了这样的错误，我该如何解决这个问题？

The file might have been edited with an editor that insert a Unicode BOM (Byte Order Mark).
该文件可能已使用插入 Unicode BOM（字节顺序标记）的编辑器进行了编辑。
Have a look to the first line contents with:
看看第一行的内容：
od -c autoinstall | head -1
or
或者
hd -n 16 autoinstall
If you see unexpected characters before #!/usr/bin/sh, you might try one of the methods described here Using awk to remove the Byte-order markto remove the BOM.
如果您之前看到意外字符#!/usr/bin/sh，您可以尝试使用此处描述的方法之一使用 awk 删除字节顺序标记以删除 BOM。

There can be two problems here:
这里可能有两个问题：
The file doesn't exist. Usually, for
sh, the path is/bin/sh, so it should be#!/bin/shYou're editing the file on Windows. Windows uses CR+LF as line ending. Unix (and Linux) uses just LF. So for Linux, the command reads "execute
/bin/sh<CR>andsh<CR>doesn't exist.
该文件不存在。通常，对于
sh，路径是/bin/sh，所以应该是#!/bin/sh您正在 Windows 上编辑文件。Windows 使用 CR+LF 作为行尾。Unix（和 Linux）只使用 LF。因此，对于 Linux，该命令显示为“执行
/bin/sh<CR>并且sh<CR>不存在。
Solution: When editing the file, make sure you use Unix line endings.
解决方案：编辑文件时，请确保使用 Unix 行结尾。
