I have been following the video self-study for several days Python full stack development, today decided to listen to the teacher, began to write a blog, heard that the great God has come back to write a blog to record their growth. I particularly seriously follow this video to learn, (they start before the guarantee, I also wrote a copy, hahaha ...) I am now a quasi-college student, ready to learn programming, to be a programmer in the future, hahaha. I heard the programmer is very hard, but it seems to earn a lot of AH.       And I seem to like only computer this aspect, so I want to shine in this industry. Some days ago, I learned some Linux commands:
  1. PWD View your current directory/root= computer/e-disk
  2. /is the root directory
  3. Switch CD 111 switch to 111 for CD (change directory)
  4. LS view files in the current directory
  5. /rwxr-xr-x-File D directory
  6. Ls-l listing the current directory detail file information
  7. LS-LH user-friendly display file list h =human LS-LH 111 See how many files
  8. Ls-a Show hidden files
  9. Cd.. Return to the previous level directory CD. /.. /.. /Return to Level Three
  10. Vim. Test Create a hidden file (not a folder) press I into insert (insert mode) to finish writing the file press ESC to exit, and then press shift+: then enter WQ and then hit enter to save and exit.
  11. Cat 111 shows this file
  12. More 111 slowly look at this file enter (a line of the look) space (one page to see)
  13. mkdir 111 Creating 111 folders
  14. Mkdir-p creation of Cn/hebei/xingtai recursion
  15. MV 111 222/move 111 to 222
  16. Tree 111 shows the structure of the 111 directory
  17. DF View disk Size
  18. Df-h user-friendly display disk usage
  19. Date system time
  20. Kill 27317 (Process number) Enter End 27317 Program
  21. Top View system Performance Q exit
            cpu:                       user: User processes account for cpu                  System: The operating system itself accounts for cpu  & nbsp               IDLE:CPU idle rate                   Iowait:cpu time to wait for IO than          MEM (Memory):                & nbsp;total:1000m                  usage: Memory usage   800m                  FREE: Memory idle  200M                &NBS P Buffered: Cache   500m            Total Free mem = free + cached +buffered =740m  &nbs P          total usage = 1000m-740m=260m
    1. Find/-name *111* fuzzy query by file name
    2. Find/-size +90m |xargs ls-lh view files by size
    3. RM Delete File rm-rf111 (Basic unrecoverable delete)
Well, that's a lot of statistics. To keep the habit of blogging. Keep going. Come on!
