如何使用shell脚本创建没有ACL的文件...我只想要chmod 644 {filename}？此脚本采用pgn文件并分离各个游戏分数（pgn国际象棋符号），并根据增加的提供值将游戏写入单个文件.6444.pgn 6445.pgn ... 6446.pgn等此脚本已正常工作就在我从Linux Mint 17升级到LM 18之前。但不再是。

# (Fixes errors in Igor's game submissions and writes the individual gamescores from larger pgn file )
# (And convert xx00 to XXXX.pgn)

offset=$2; dos2unix -q $ULFILE; awk -v RS='^$' -v ORS= '{gsub(/{\n/, "{")} 1' $ULFILE >junk.txt;
(A lot of awk and sed goes here)
cp junk.txt $TARGET;
chmod 644 $TARGET;
cd /home/rmack/www/cccr/games/; csplit -s $TARGET /Event\ / {*}; rm /home/rmack/www/cccr/games/xx00;
for file in xx[0-9]*; do
num0=${file##*x}; num=${num0#0}; (( newnum = num + offset ))
mv $file ${newnum}.pgn; branch=${newnum}.pgn;
echo $newnum; chmod 777 $branch; cat "$AUTHOR" >> "$branch";
echo "$AUTHOR" >> "$branch";
chmod 644 $branch;
done

"If the file or directory has extended security information, the permissions field printed by the -l option is followed by a '+' character."
This generally means the file is encumbered with access restrictions outside of the traditional Unix permissions - likely Access Control List (ACL).
