Common Commands under Linux

1. Delete a folder

Delete a directory in Linux very simple, many people are still accustomed to use rmdir, but once the directory is not empty, it fell into deep distress, now use the RM-RF command can be resolved.
Direct RM is available, but add two parameters-rf that is: RM-RF   directory Name
-R is recursive down, no matter how many levels of directory, delete
-F is directly forcibly deleted, without any hint of meaning

To delete a folder instance: rm-rf/var/log/httpd/access
The/var/log/httpd/access directory and all files and folders under it will be deleted

Need to be reminded: Use this RM-RF must be extra careful, Linux does not recycle Bin, once deleted is not recoverable.

Of course, RM has more parameters and usage, and man RM can view the

Delete File Usage instance: Rm-f/var/log/httpd/access.log
This file will be forcibly deleted/var/log/httpd/access.log
2. wget whole Station Download
Because the winter vacation back home no nets, Jekyll manual can not be used online, just want to save it, a page a page Ctrl s too slow, think of the wget command
I used the following code, the entire site to download all down, including CSS and JS

Wget-p-np-k-R http://jekyllcn.com/

The entire site is automatically saved as a jekyllcn.com folder

-P (--page-requisites)

Download all the resources needed to display the entire page, including the embedded image and CSS style files.

-NP (--no-parent)

Downloads only the files in the given directory, not the files in its parent directory, even if there are connections to files in the parent directory on some pages. This is more necessary, if not qualified, would have only wanted to download www.example.com/blog/in the blog post, it is likely that the entire www.example.com have been downloaded.

-K (--convert-links)

This option will fix the links between HTML, CSS, image and other resources after the entire site is downloaded, so that they all point to the downloaded local file, which is suitable for local browsing.

-R (--recursive recursion) specify recursive download. (Specify recursive download)

3. Compress and decompress zip files

Zip [parameters] [file name after packaging] [packaged directory path]

linux zip command argument list:
