linux 中删除当前目录下指定文件外所有的文件

1、ls + grep + xargs  实现

a、

root@DESKTOP-1N42TVH:/home/test# touch test{1..10}.txt
root@DESKTOP-1N42TVH:/home/test# touch abc{1..10}.csv
root@DESKTOP-1N42TVH:/home/test# touch kk.map mn.ped
root@DESKTOP-1N42TVH:/home/test# ls
abc1.csv   abc2.csv  abc4.csv  abc6.csv  abc8.csv  kk.map  test1.txt   test2.txt  test4.txt  test6.txt  test8.txt
abc10.csv  abc3.csv  abc5.csv  abc7.csv  abc9.csv  mn.ped  test10.txt  test3.txt  test5.txt  test7.txt  test9.txt
root@DESKTOP-1N42TVH:/home/test# ls | grep -v "kk.map"
abc1.csv
abc10.csv
abc2.csv
abc3.csv
abc4.csv
abc5.csv
abc6.csv
abc7.csv
abc8.csv
abc9.csv
mn.ped
test1.txt
test10.txt
test2.txt
test3.txt
test4.txt
test5.txt
test6.txt
test7.txt
test8.txt
test9.txt
root@DESKTOP-1N42TVH:/home/test# ls | grep -v "kk.map" | xargs rm -rf   ## 删除除kk.map外以外的所有文件
root@DESKTOP-1N42TVH:/home/test# ls
kk.map

 

b、

root@DESKTOP-1N42TVH:/home/test# ls
root@DESKTOP-1N42TVH:/home/test# touch test{1..10}.txt
root@DESKTOP-1N42TVH:/home/test# touch abc{1..10}.csv
root@DESKTOP-1N42TVH:/home/test# touch kk.map mn.ped
root@DESKTOP-1N42TVH:/home/test# ls
abc1.csv   abc2.csv  abc4.csv  abc6.csv  abc8.csv  kk.map  test1.txt   test2.txt  test4.txt  test6.txt  test8.txt
abc10.csv  abc3.csv  abc5.csv  abc7.csv  abc9.csv  mn.ped  test10.txt  test3.txt  test5.txt  test7.txt  test9.txt
root@DESKTOP-1N42TVH:/home/test# ls | grep -E -v "kk.map|mn.ped"
abc1.csv
abc10.csv
abc2.csv
abc3.csv
abc4.csv
abc5.csv
abc6.csv
abc7.csv
abc8.csv
abc9.csv
test1.txt
test10.txt
test2.txt
test3.txt
test4.txt
test5.txt
test6.txt
test7.txt
test8.txt
test9.txt
root@DESKTOP-1N42TVH:/home/test# ls | grep -E -v "kk.map|mn.ped" | xargs rm -rf  ## 删除除kk.map和mn.ped以外的所有文件
root@DESKTOP-1N42TVH:/home/test# ls
kk.map  mn.ped

 

2、find实现

a、

root@DESKTOP-1N42TVH:/home/test# ls
root@DESKTOP-1N42TVH:/home/test# touch abc{1..10}.csv
root@DESKTOP-1N42TVH:/home/test# touch kk.map mn.ped
root@DESKTOP-1N42TVH:/home/test# touch test{1..10}.txt
root@DESKTOP-1N42TVH:/home/test# ls
abc1.csv   abc2.csv  abc4.csv  abc6.csv  abc8.csv  kk.map  test1.txt   test2.txt  test4.txt  test6.txt  test8.txt
abc10.csv  abc3.csv  abc5.csv  abc7.csv  abc9.csv  mn.ped  test10.txt  test3.txt  test5.txt  test7.txt  test9.txt
root@DESKTOP-1N42TVH:/home/test# find ./ -name "kk.map"
./kk.map
root@DESKTOP-1N42TVH:/home/test# find ./ ! -name "kk.map"
./
./test8.txt
./abc1.csv
./abc8.csv
./abc3.csv
./test6.txt
./test10.txt
./test2.txt
./abc10.csv
./test1.txt
./test9.txt
./test5.txt
./abc7.csv
./test7.txt
./abc2.csv
./abc6.csv
./abc4.csv
./test3.txt
./abc5.csv
./abc9.csv
./mn.ped
./test4.txt
root@DESKTOP-1N42TVH:/home/test# find ./ ! -name "kk.map" -exec rm -rf {} \; #删除除kk.map文件以外的所有文件
rm: refusing to remove '.' or '..' directory: skipping './'
root@DESKTOP-1N42TVH:/home/test# ls
kk.map

 

b、

root@DESKTOP-1N42TVH:/home/test# touch kk.map mn.ped
root@DESKTOP-1N42TVH:/home/test# touch test{1..10}.txt
root@DESKTOP-1N42TVH:/home/test# touch abc{1..10}.csv
root@DESKTOP-1N42TVH:/home/test# ls
abc1.csv   abc2.csv  abc4.csv  abc6.csv  abc8.csv  kk.map  test1.txt   test2.txt  test4.txt  test6.txt  test8.txt
abc10.csv  abc3.csv  abc5.csv  abc7.csv  abc9.csv  mn.ped  test10.txt  test3.txt  test5.txt  test7.txt  test9.txt
root@DESKTOP-1N42TVH:/home/test# find ./ ! -name "kk.map" ! -name "mn.ped"
./
./test8.txt
./abc1.csv
./abc8.csv
./abc3.csv
./test6.txt
./test10.txt
./test2.txt
./abc10.csv
./test1.txt
./test9.txt
./test5.txt
./abc7.csv
./test7.txt
./abc2.csv
./abc6.csv
./abc4.csv
./test3.txt
./abc5.csv
./abc9.csv
./test4.txt
root@DESKTOP-1N42TVH:/home/test# find ./ ! -name "kk.map" ! -name "mn.ped" -exec rm -rf {} \;   ## 删除除kk.map和mn.ped以外的所有文件
rm: refusing to remove '.' or '..' directory: skipping './'
root@DESKTOP-1N42TVH:/home/test# ls
kk.map  mn.ped

 

3、rm !实现

a、

root@DESKTOP-1N42TVH:/home/test# touch kk.map mn.ped
root@DESKTOP-1N42TVH:/home/test# touch test{1..10}.txt
root@DESKTOP-1N42TVH:/home/test# touch abc{1..10}.csv
root@DESKTOP-1N42TVH:/home/test# ls
abc1.csv   abc2.csv  abc4.csv  abc6.csv  abc8.csv  kk.map  test1.txt   test2.txt  test4.txt  test6.txt  test8.txt
abc10.csv  abc3.csv  abc5.csv  abc7.csv  abc9.csv  mn.ped  test10.txt  test3.txt  test5.txt  test7.txt  test9.txt
root@DESKTOP-1N42TVH:/home/test# rm !(kk.map)   ## 删除除kk.map文件以外的所有文件
root@DESKTOP-1N42TVH:/home/test# ls
kk.map

 

b、

root@DESKTOP-1N42TVH:/home/test# touch kk.map mn.ped
root@DESKTOP-1N42TVH:/home/test# touch test{1..10}.txt
root@DESKTOP-1N42TVH:/home/test# touch abc{1..10}.csv
root@DESKTOP-1N42TVH:/home/test# ls
abc1.csv   abc2.csv  abc4.csv  abc6.csv  abc8.csv  kk.map  test1.txt   test2.txt  test4.txt  test6.txt  test8.txt
abc10.csv  abc3.csv  abc5.csv  abc7.csv  abc9.csv  mn.ped  test10.txt  test3.txt  test5.txt  test7.txt  test9.txt
root@DESKTOP-1N42TVH:/home/test# rm !(kk.map|mn.ped)   ## 删除除kk.map和mn.ped以外的所有文件
root@DESKTOP-1N42TVH:/home/test# ls
kk.map  mn.ped
