SVN 预提交挂钩以限制文件扩展名被提交

在 Collabnet SVN 的预提交脚本中使用以下代码来限制特定文件扩展名的提交，但它会提交所有文件。你能告诉我哪里错了吗？

#!/bin/sh

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

SVNLOOK=/home/csvn/csvn/bin/svnlook

LOGMSG=`$SVNLOOK log -t "$TXN" "$REPOS" | grep "[a-zA-Z0-9]" | wc -c`

if [ "$LOGMSG" -lt 10 ];
then
  echo -e "\n===========================================================" 1>&2
  echo -e "|| COMMENTS ARE MADE MANDATORY.PLEASE ENTER RELEVANT COMMENT & COMMIT AGAIN Sanjeev sas||" 1>&2
  echo -e "===========================================================" 1>&2
  exit 1
fi

$SVNLOOK changed -t $TXN $REPOS | awk '
BEGIN {
FILTER=".(sh|xls|xlsx|pdf|jpg|JPG|gif|GIF|png|PNG|doc|DOC|docx|DOCX|mpg|swf|avi|mp3|mp4|zip|rar|gz|csv|o|obj|tar|gz|JPEG|jpeg|WMV|wmv|DAT|dat|3GP|3gp|MPEG|mpeg|VOD|vod|ear|jar|war|exe|ppt|PPT|PPTX|pptx|7z|iso|ISO|EAR|WAR|JAR|msg|MSG|rtf|RTF|xlsm|XLSM|vsd|VSD|dot|DOT|camrec|ECF|ecf|mff|MFF|class|CLASS)$"
}
{
 for (i = 1; i < 2; i++) $i = ""; sub(/^ */, "");
 if(match(tolower($1),FILTER))
 { 
     print "File" $1 "is not allowed file type to commit" 
     exit 1
 }
}'    

exit 0

下面的脚本对我有用！ 请让我知道你的想法

#!/bin/bash

REPOS=$1
TXN=$2
AWK=/bin/awk
SVNLOOK="/usr/bin/svnlook";

#Put all the restricted formats in variable FILTER
FILTER=".(sh|xls|xlsx|exe|xlsm|XLSM|vsd|VSD|bak|BAK|class|CLASS)$"

# Figure out what directories have changed using svnlook.
FILES=`${SVNLOOK} changed ${REPOS} -t ${TXN} | ${AWK} '{ print $2 }'` > /dev/null

for FILE in $FILES; do

#Get the base Filename to extract its extension
NAME=`basename "$FILE"`

#Get the extension of the current file
EXTENSION=`echo "$NAME" | cut -d'.' -f2-`

#Checks if it contains the restricted format
if [[ "$FILTER" == *"$EXTENSION"* ]]; then
    echo "Your commit has been blocked because you are trying to commit a restricted file." 1>&2
    echo "Please contact SVN Admin. -- Thank you" 1>&2
    exit 1

fi

done
exit 0
