# 删除当前目录下所有 *.txt文件，除了test.txt
rm `ls *.txt|egrep -v test.txt`
#或者
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.1|egrep -v '(access-2010-09-06.log|error-2010-09-06.log)'`
rm -f `ls *.log|egrep -v '(access-2010-09-06.log|error-2010-09-06.log)'`
rm -f `ls *.log|egrep -v '(20100906.log)'`
注意：上面所用的符号是‘`’，而不是单引号
rm -rf
ls |egrep -v bb删除所有，保留bb 目录
# 注意：如下这样的写法不生效，因为带有*
rm -rf `ls /tmp/test/apptf/* | egrep -v upload`
# 这样写才可以
rm -rf `ls /tmp/test/apptf/ | egrep -v upload`
# 具体演示
/tmp/test # cd apptf
/tmp/test/apptf # pwd
/tmp/test/apptf
/tmp/test/apptf # ll
