Bash文件脚本转义用户输入(Bash file script escaping user input)

Bash文件脚本转义用户输入(Bash file script escaping user input)

这个bash脚本在Mac终端上运行时，需要询问用户输入，然后需要检查给定文件中是否存在字符串"PLACEHOLDER_BACKEND_NAME="user-input" ，如果不存在，则应退出脚本。

echo -e "${YELLOW}enter app name${WHITE}" read name line=grep $name /path/to/file/entrypoint.sh if [[ line != "PLACEHOLDER_BACKEND_NAME=\"$name\"" ]] ; then exit 1 fi

它需要很多调整，因为我不太熟悉bash脚本。 有什么建议么？ 谢谢

This bash script when run on Mac terminal, it needs to ask for user input, then it needs to check if a a string "PLACEHOLDER_BACKEND_NAME="user-input" exists in a given file and if not it should exit the script.

echo -e "${YELLOW}enter app name${WHITE}" read name line=grep $name /path/to/file/entrypoint.sh if [[ line != "PLACEHOLDER_BACKEND_NAME=\"$name\"" ]] ; then exit 1 fi

It needs much tuning as I am not very familiar with bash scripts. any suggestions? thx

您的代码需要稍微调整一下：

echo -e "${YELLOW}enter app name${WHITE}" read -r name if ! grep -q PLACEHOLDER_BACKEND_NAME="\"$name\"" /path/to/file/entrypoint.sh; then exit 1 fi

Your code needs a little tweaking:

echo -e "${YELLOW}enter app name${WHITE}" read -r name if ! grep -q PLACEHOLDER_BACKEND_NAME="\"$name\"" /path/to/file/entrypoint.sh; then exit 1 fi
