bash：意外标记‘

我有这个 bash

#!/bin/bash
set -o nounset

if [ $# != 2 ]
then
    echo "Invalid arguments."
    echo "Try: $0 <Project Name> <Version>"
    exit
fi

if [ -d ./$1 ]; then
    echo "Error: Project $1 exists."
    exit
fi

vivado -mode batch -source create_vivado_proj.tcl -tclargs $1 $2

xsdk -batch -source create_sdk_proj.tcl $1 $2

curr_dir=`pwd`
project_dir="$curr_dir/$1"

# Create bootable files
mkdir "$project_dir/boot"
fsbl_path="$project_dir/$1.sdk/fsbl/Debug/fsbl.elf"
bit_path="$project_dir/$1.runs/impl_1/system_wrapper.bit"
config_path="$project_dir/$1.sdk/sysconfig/Debug/sysconfig.elf"
bif_path="$project_dir/boot/boot.bif"

echo "the_ROM_image:"               > $bif_path
echo "{"                            >> $bif_path
echo "     [bootloader]$fsbl_path"  >> $bif_path
echo "     $bit_path"               >> $bif_path
echo "     $config_path"            >> $bif_path
echo "}"                            >> $bif_path

# Create BOOT.bin
bootgen -image "$bif_path" -o i "$project_dir/boot/BOOT.bin"

echo "Generate BOOT.bin at"
echo "$project_dir/boot/BOOT.bin"

但是当我在终端运行此代码时

./build.sh <Project ov7670_VDMA_VGA><v3>

我收到这个错误

bash: syntax error near unexpected token `<'

答案1

正如两个人所评论的那样，调用脚本的语法使用了不按字面意思理解的字符。以下是尖括号：

<Project Name> <Version>

暗示项目名称和版本是必需参数。这在 shell 脚本代码中得到了证实，它明确检查了两个参数：

if [ $# != 2 ]
then
    echo "Invalid arguments."
    ...

调用脚本的正确方法是：

./build.sh "Project ov7670_VDMA_VGA" v3

...我引用了第一个参数，以便“Project”和“ov7670_VDMA_VGA”之间的空格不会误解作为两个独立的论点。
