svn提交添加注释设置

导读	当我们用tortoisesvn，提交代码时，有很多人不喜欢写注释的，代码版本多了，根本搞不清，哪个版本改了什么东西？所以如果加一些注释的话，我们看起来，也方便很多。所以在提交的时候，我会强制要求，写注释。

1, cd /home/administrator/www/svn_test svn_test是一个代码仓库

2,mv ./hooks/pre-commit.tmpl ./hooks/pre-commit 将代码仓库根目录下，hooks文件夹中的pre-commit.tmpl文件重命名为pre-commit

3,vim ./hooks/pre-commit

REPOS="$1"
TXN="$2"

# Make sure that the log message contains some text.
SVNLOOK=/usr/bin/svnlook
$SVNLOOK log -t "$TXN" "$REPOS" | \
grep "[a-zA-Z0-9]" > /dev/null || exit 1

# Exit on all errors.
set -e

# Check that the author of this commit has the rights to perform
# the commit on the files and directories being modified.
"$REPOS"/hooks/commit-access-control.pl "$REPOS" $TXN \
"$REPOS"/hooks/commit-access-control.cfg

# All checks passed, so allow the commit.
exit 0

上面是修改前的，看一下，下面的，修改后的。

REPOS="$1"
TXN="$2"

# Make sure that the log message contains some text.
SVNLOOK=/usr/bin/svnlook

LOGMSG=`$SVNLOOK log -t $TXN $REPOS | wc -m` //定义个变量，注意这里不是单引号

#$SVNLOOK log -t "$TXN" "$REPOS" | \ //把这一行和下面的一行注释掉
# grep "[a-zA-Z0-9]" > /dev/null || exit 1

echo $LOGMSG > /home/administrator/www/aaa.txt //为了测试变量用的，查看$LOGMSG有没有值,最后要注释掉
if [ "$LOGMSG" -lt 48 ] //这里为什么是48呢，一个汉字对应16个字符
then
echo "\n至少输入4个汉字" >&2 //必须填四个汉字
exit 1
fi

# Exit on all errors.
#set -e

# Check that the author of this commit has the rights to perform
# the commit on the files and directories being modified.
#"$REPOS"/hooks/commit-access-control.pl "$REPOS" $TXN \ //把这一行和下面的一行注释掉。
# "$REPOS"/hooks/commit-access-control.cfg

# All checks passed, so allow the commit.
exit 0

4,保存后，我们要给pre-commit这个文件，加可执行权限chmod +x pre-commit,有一点在说一下就是$SVNLOOK 前面的不是单引号，
