需要将.log.1结尾的文件更改为.log
命令如下：
# for file in $(ls -lh | awk ‘$NF~/log/{print $NF}‘);do newfile=$(echo $file | sed ‘s/.1//g‘); mv $file $newfile; done
# 美化一下
for file in $(ls -lh | awk ‘$NF~/log/{print $NF}‘); do
newfile=$(echo $file | sed ‘s/.1//g‘)
mv $file $newfile
done
法二：
# ls *.1 | sed -r "s#(.*).1#mv & 1#" | bash
注：
sed替换标记：
1表示前面第一个左括号所表示的内容,2表示前面第二个左括号中表示的内容，以此类推
&表示前面匹配到的内容
