./MakeOVPN.sh：第 12 行：[!-fDanielIphone.crt]：找不到命令

Question

我正在尝试在我的 raspberry pi 上使用开放式 vpn 创建一个 VPN，我目前正在使用终端输入一个文件来为我要连接的设备。使用 BBC 的分步指南。我已经尝试解决这个问题大约一个小时了，但我一直收到同样的错误，请帮忙。

#!/bin/bash
DEFAULT="Default.txt"
FILEEXT=".ovpn"
CRT=".crt"
KEY=".3des.key"
CA="ca.crt"
TA="ta.key"

echo "Please enter an existing Client Name:"
read NAME

if [!-f$NAME$CRT]; then
echo "[ERROR]: Client Public Key Certificate not found: $NAME$CRT"
exit
fi
echo "Client's cert found:$NAME$CR"
if [!-f$NAME$KEY]; then
echo "[ERROR]: Client 3des Private Key not found:$NAME$KEY"
exit
fi
echo "Client's Private Key found:$NAME$KEY"

Error From Code

Answer 1

尝试在您的 if 语句中添加额外的空格：

if [ ! -f $NAME$CRT ]; then

现在完整的脚本是：

#!/bin/bash
DEFAULT="Default.txt"
FILEEXT=".ovpn"
CRT=".crt"
KEY=".3des.key"
CA="ca.crt"
TA="ta.key"

echo "Please enter an existing Client Name:"
read NAME

if [ ! -f $NAME$CRT ]; then
echo "[ERROR]: Client Public Key Certificate not found: $NAME$CRT"
exit
fi
echo "Client's cert found:$NAME$CR"

这里有一个展示它有效的演示：

$ chmod +x ./myscript 

$ touch foo.crt

$ ./myscript 
Please enter an existing Client Name:
foo
Client's cert found:foo

$ ./myscript
Please enter an existing Client Name:
bar
[ERROR]: Client Public Key Certificate not found: bar.crt

Answer 2

Try this 

#!/bin/bash
`DEFAULT="Default.txt"
FILEEXT=".ovpn"
CRT=".crt"
KEY=".3des.key"
CA="ca.crt"
TA="ta.key"

echo "Please enter an existing Client Name:"
read NAME

if[ !-f $NAME$CRT ]; then
echo "[ERROR]: Client Public Key Certificate not found: $NAME$CRT"
exit
fi
echo "Client's cert found:$NAME$CR"

Answer 3

我所做的只是在 if 之后添加一个 space 并且它已经超越了你的错误。

#!/bin/bash
DEFAULT="Default.txt"
FILEEXT=".ovpn"
CRT=".crt"
KEY=".3des.key"
CA="ca.crt"
TA="ta.key"

echo "Please enter an existing Client Name:"
read NAME

if [ ! -f $NAME$CRT ]; then
echo "[ERROR]: Client Public Key Certificate not found: $NAME$CRT"
exit
fi
echo "Client's cert found:$NAME$CR"
