Delete files other than the specified file

First, delete files and folders under Linux Common commands are as follows:

Delete Files: RM file

Delete folder: Rm-rf dir

It is important to note that rmdir can only delete empty folders.

Ii. Delete all documents other than the development document (folder)?

1, Method 1, the more troublesome practice is:

Copy the files that you want to keep to a different folder, and then delete the directory, and then move it back to what you want to keep.

MV Keep. /#保留文件 (clip) Keep

RM-RF * #删除当前文件夹里的所有文件

Mv.. /keep./#将原来的东西移动回来

2, Method 2, you need to do in the current folder:

Rm-rf! (keep) #删除keep文件之外的所有文件

Rm-rf! (Keep1 | keep2) #删除keep1和keep2文件之外的所有文件

Completely remove files from Linux

Shred how to delete files completely:

$ shred-u File

Shred will overwrite the node and data block where the file resides with some random content, and delete the file (-u parameter).

If you want to clear a bit more thoroughly you can add the-z parameter, which means to fill with random data, and then fill it with 0.

$ shred-u-Z File

In addition shred can also clear the entire partition or disk, such as to completely clear the contents of the/DEV/SDB1 partition can be:

$ SHRED/DEV/SDB1 (note do not add-u parameter)

Detailed parameters of the shred:

-F,--force Change permissions allow write (if necessary)

-N,--iterations=n rewrite n times, default is 3 times

--random-source=file reading data from a specified file

-S,--size=n the file to a fixed size (suffixes such as K, M, C, etc. can be used)

-U,--remove truncate and remove files after rewriting

-V,--verbose show progress

-Z,--zero-add with 0 coverage data
