在使用SVN進行項目管理的過程中，為了對各版本送出狀況進行了解，我們需要在SVN送出過程中強制使用者輸入一定的日志。
下面介紹一下如何來限制使用者SVN送出時必須輸入日志。
步驟：
1、進入SVN倉庫的hooks目錄，把pre-commit.tmpl檔案重命名為pre-commit
2、修改pre-commit檔案
修改前：
REPOS="$1" TXN="$2" # Make sure that the log message contains some text. SVNLOOK=/usr/bin/svnlook $SVNLOOK log -t "$TXN" "$REPOS" | \ grep "[a-zA-Z0-9]" > /dev/null || exit 1 # Check that the author of this commit has the rights to perform # the commit on the files and directories being modified. commit-access-control.pl "$REPOS" "$TXN" commit-access-control.cfg || exit 1 # All checks passed, so allow the commit. exit 0 複制
修改後：
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 # Check that the author of this commit has the rights to perform # the commit on the files and directories being modified. #commit-access-control.pl "$REPOS" "$TXN" commit-access-control.cfg || exit 1 LOGMSG=`$SVNLOOK log -t "$TXN" "$REPOS" | grep "[a-zA-Z0-9]" | wc -c` if [ "$LOGMSG" -lt 10 ];#要求注釋不能少于10個字元 then echo -e "\n注釋不能為空，且字數必須大于10個字元." 1>&2 exit 1 fi # All checks passed, so allow the commit. exit 0 複制
其實就是把源檔案中的以下3行進行注釋：
$SVNLOOK log -t "$TXN" "$REPOS" | \ grep "[a-zA-Z0-9]" > /dev/null || exit 1 commit-access-control.pl "$REPOS" "$TXN" commit-access-control.cfg || exit 1 複制
然後添加以下幾行指令：
LOGMSG=`$SVNLOOK log -t "$TXN" "$REPOS" | grep "[a-zA-Z0-9]" | wc -c` if [ "$LOGMSG" -lt 10 ];#要求注釋不能少于10個字元 then echo -e "\nLog message cann't be empty! you must input more than 10 chars as comment!." 1>&2 exit 1 fi 複制
3、把pre-commit檔案修改為755
chmod 755 pre-commit 複制
修改完後，測試了一下，在沒有輸入日志時送出SVN，提示錯誤
Commit failed (details follow): Commit blocked by pre-commit hook (exit code 1) with output: 注釋不能為空，且字數必須大于10個字元 複制
輸入一定的字數後送出成功！
這裡的錯誤提示可以修改echo 裡面輸出的内容：
echo -e "\nLog message cann't be empty! you must input more than 10 chars as comment!。" 1>&2 複制
