检查提交消息中的特定字符串 - SVN Precommit Hook答案

【问题标题】：Checking for specific string in commit message - SVN Precommit Hook检查提交消息中的特定字符串 - SVN Precommit Hook

【问题描述】：

我期望 svn 提交消息中的格式如下。

描述：（一些变化的描述）
实体：（变更申请号）

如果提交时的评论不符合上述格式，则应抛出错误消息。这个想法是检查提交消息中的关键字符串“描述”和“实体”。我也在检查消息中是否存在评论。

我正在使用以下代码，但无法检查字符串“描述”是否正常工作。（不过，空评论的检查工作正常。）你能告诉我可能做错了什么吗？

REPOS=$1
TXN=$2
LOG="/home/svn/testSVN/logs/precommithook.log"

GREP=/bin/grep
ECHO=/bin/echo
SVN="/usr/bin/svn";
SVNLOOK="/usr/bin/svnlook";

#Logs the current Transaction ID
"${ECHO}" "Transcation Id ${TXN}" >> "$LOG"

$SVNLOOK log "$REPOS" -t "$TXN" | grep "[a-zA-Z0-9]" > /dev/null

GREP_STATUS=$?
if [ $GREP_STATUS -ne 0 ]
then
"${ECHO}" "No Log comments present" >> "${LOG}"
echo "Your commit has been blocked because you didn't give any log message" 1>&2
echo "Please write a log message describing the purpose of your changes and" 1>&2
echo "then try committing again. -- Thank you" 1>&2
exit 1
fi

$SVNLOOK log "$REPOS" -t "$TXN" | grep [a-zA-Z0-9] | grep -q "Description" > /dev/null

GREP_DESCRIPTION_STATUS=$?
if [ $GREP_DESCRIPTION_STATUS –ne 0 ]
then
  "${ECHO}" "Description not found in the comment" >> "${LOG}"
   echo "Your commit has been blocked because you didn't give the Description in  your     commit message" 1>&2
   echo "Please write a log message describing the purpose of your changes and" 1>&2
   echo "then try committing again. -- Thank you" 1>&2
   exit 1
fi
exit 0

我也尝试了简单的 grep "Description" 和 grep -w "Description"。还是收不到。

【解决方案1】：

有一个小的解决方法。二手

LOGMSG=$($SVNLOOK log -t "$TXN" "$REPOS" | grep -w "Description" | wc -c)
if [ "$LOGMSG" -le 0 ]; then echo -e "Please provide a description when committing changes." 1>&2
exit 1
fi
