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

Question

我正在尝试将 bash 脚本用作 git commit-msg 钩子。 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.git/COMMIT_EDITMSG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

我想出了这个：

#!/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
