Git hook commit-msg 以确保提交消息包含符合正则表达式的字符串答案

【问题描述】：

我正在尝试将 bash 脚本用作 git commit-msg 挂钩。本质上，我想确保提交消息包含与正则表达式匹配的字符串。我的正则表达式是正确的，但我不确定如何检查 .git/COMMIT_EDITMSG 中包含的消息是否与正则表达式匹配。

#!/bin/sh
#
# This hook verifies that the commit message contains a reference to a tfs item

RED=$(tput setaf 1)
NORMAL=$(tput sgr0)
# Regex to validate a string contains "#" followed by 4 or 5 digits anywhere in the commit message
regex="#[0-9]{4,5}($|[^0-9])"

# I NEED TO FIGURE OUT HOW TO READ THE CONTENTS OF THIS FILE AND ENSURE IT MATCHES THE REGEX
echo "MSG = $1" # This prints "MSG = .git/COMMIT_EDITMSG"

# If the commit message does not match the regex
if ! [[ $1 =~ $regex ]]; then
  echo "${RED}ERROR - Missing tfs item in commmit message.$NORMAL"
  exit 1
else
  echo "MESSAGE IS GOOD?"
fi

exit 0

【问题讨论】：

您是否寻求帮助以确保此代码适用于所有情况？（这就是我的解释）。我们必须更多地了解你试图诱捕的案件。照原样，一件事可能会导致您的代码出现问题。我建议将线路更改为 if ! [[ "$1" =~ "$regex" ]]; then 。祝你好运！
我只是想弄清楚如何读取文件的内容并针对我的正则表达式运行它。

我是这样想的：

#!/bin/sh
#
# This hook verifies that the commit message contains a reference to a tfs item

RED=$(tput setaf 1)
NORMAL=$(tput sgr0)
# Regex to validate a string contains "#" followed by 4 or 5 digits anywhere in the commit message
regex="#[0-9]{4,5}($|[^0-9])"
file=`cat $1` # The file that contains the commit message

# If the commit message does not match the regex
if ! [[ $file =~ $regex ]]; then
  echo "${RED}ERROR - Missing tfs item in commmit message.$NORMAL"
  exit 1
else
  echo "MESSAGE IS GOOD?"
fi

exit 0
