我正在尝试在 bash 脚本中解压缩文件，但是在重复输出“解压缩代理文件”消息后，我收到“段错误（核心转储）”错误。

请参阅下面的脚本：

cat /usr/local/bin/release-agent.sh
#! /bin/bash -e

source functions.sh

        else

                        exit 0
                else

                        if [[ ${ext} != "zip" ]]; then

输出函数只是为了使输出更容易而编写的，下面仅供参考：

output() {
#
# Useage output "string" [colour] {flash}
#

if [[ $3 == "flash" ]]; then
        _blink=";5"
else
        _blink=""
fi

case $2 in
        grey)
                echo -e "\e[30;1${_blink}m${1}\e[0m"
                ;;
        red)
                echo -e "\e[31;1${_blink}m${1}\e[0m"
                ;;
        green)
                echo -e "\e[32;1${_blink}m$1\e[0m"
                ;;
        yellow)
                echo -e "\e[33;1${_blink}m$1\e[0m"
                ;;
