rm排除特定文件

删除当前目录下所有 *.txt文件，除了test.txt

rm `ls *.txt|egrep -v test.txt`
rm `ls *.txt|awk '{if($0 != "test.txt") print $0}'`

排除多个文件

rm `ls *.txt|egrep -v '(test.txt|fff.txt|ppp.txt)'`
rm -f `ls *.log|egrep -v '(access.log|error.log)'`
rm -f `ls *.log|egrep -v '(access.log)'`

注意：上面所用的符号不是单引号，是 `

find查找排除

rm `find . -name *.txt | egrep -v ‘（test.txt|fff.txt|ppp.txt)'`
