Linux Management files and directories

The Linux file is rooted as the starting point, the Linux/Representative start is the root, because Linux is the inverted root you can directly understand as a tree upside down, first the roots, then the trunk, then the branches finally reach the leaves such as:/home/user/1.txt

Let's take a look at the path to the file.

[Email protected] user]# Ls/home/user/1.txt/home/user/1.txt

First, the common documents and directories of the management order it!

LS: List files

[Email protected] user]# Ls1.txt

CD: Switch directories such as

[[email protected] user]# pwd/home/user[[email protected] user]# cd/usr/local/[[email protected] local]# pwd/usr/local

PWD: Displays the current directory location

[Email protected] user]# Pwd/home/user

mkdir: Creating a Directory

[[email protected] user]# ls1.txt[[email protected] user]# mkdir Test[[email protected] user]# ll total dosage 4-rw-r--r--1 root ro OT 0 September 22:06 1.txtdrwxr-xr-x 2 root root 4096 September 22:10 test

CP: Copying Files or directories

[[email protected] user]# ls test/[[email protected] user]# CP 1.txt test/[[email protected] user]# ls test/1.txt

MV: Cut or rename

[[email protected] user]# ls test/1.txt[[email protected] user]# ls1.txt test[[email protected] user]# mv 1.txt 2.txt[[em AIL protected] user]# ls2.txt test[[email protected] user]# mv 2.txt test/[[email protected] user]# Lstest[[email Protect ed] user]# ls Test/1.txt 2.txt

RM: Deleting files or directories

[[email protected] user]# ls test/1.txt 2.txt[[email protected] user]# RM test/1.txt RM: Delete normal empty file "Test/1.txt"? Y[[email protected] user]# ls test/2.txt[[email protected] user]# rm-r test/rm: Do you want to enter the catalog "test"? YRM: Do you want to delete the plain empty file "Test/2.txt"? YRM: Do you want to delete the directory "test"? Y[[email protected] user]# Ls[[email protected] user]#

Second, File view

Cat: View the contents of the file, starting with the first line

[email protected] user]# cat 1.txt the IS Test page. The IS Test Page2. The IS Test page3.

TAC: View the content file, starting with the last line

[Email protected] user]# TAC 1.txt the is Test page3. The IS Test Page2. The IS Test page.

NL: View content file, display the line in passing

[[email protected] user]# nl 1.txt 1The is Test page.     2The is Test Page2. 3The is Test page3.

More: View content, split screen display, the command in the file content when the use of the effect is intuitive, omitted some of the content ~ Note--more--(25%) A screen shows One-fourth of the content

[Email protected] user]# More/etc/man.config # Generated automatically from man.conf.in by the# configure script....# T He keyword FHS would cause this behaviour (and overrides Fsstnd). # explicitly given Catdirs override.--more--(25%)

Less: Like more but less can go upside down

Head: You can view the first few lines

[Email protected] user]# Head/etc/man.config # Generated automatically from man.conf.in by the# configure script.## man  . conf from man-1.6f## For more information on this file, see the Man pages of Man (1) # and man.conf (5). # * # This file is read By mans to configure the default Manpath (also used

Tail: see only the last few lines (default 10 rows)

[Email protected] user]# tail/etc/man.config # enable/disable Makewhatis database cron updates.# If makewhatisdbupdates Variable is uncommented# and set to N or N, cron scripts #/etc/cron.daily/makewhatis.cron#/ETC/CRON.WEEKLY/MAKEWHATIS.C ron# would not update Makewhatis database.# Otherwise The database would be updated.# #MAKEWHATISDBUPDATESn

Of course, you can also use the head and tail combination to view specific rows, such as I just want to see the second line of 1.txt:

[email protected] user]# cat 1.txt the IS Test page. The IS Test Page2. The IS Test page3. [Email protected] user]# Head-2 1.txt | Tail-1the is Test Page2. [Email protected] user]#

This simple file and Directory Management view command basically OK pull
