Ps: displays the processes currently running in the system/usr/bin/ps [Option]-e: displays a complete list of each currently running process-f

Actual Operation:
--------------------------------------

1. The sshclient connects to the 10.5.1.55system (see the remote client startup instructions for securecrt.doc).

$ Cd/home/bea2/user_projects/csdomain/bin

2. view the weblogic92 service process

$ Ps-eaf | grep weblogic

Bea2 327926 331940 0 13:08:45 pts/4 grep weblogic

Description: view the logon user as prompted.Bea2Start the process, pay attention to the redBea2For processes,491796Process ID

3. Run the following command to kill the process:

$ Kill-9 491796 (find the system process number based on 2 Operations)

Note: After you execute the $ ps-eaf | grep weblogic command, the weblogic process with this process number is not displayed.

4. Start the service

$./QuickRun. sh

-------------------------------------------------------------------
2. ant-buildfile CMS_MainTrunk.xml // build package

3. vi test.txt // browse the File Content
I {insert write input}
Esc exit insert
: Wq! Write: Save and exit vi Mode
: Q! Exit vi mode without saving

4. I usually use the ps-ef command to view the server processes displayed in the form of a list; Use the command pstree to view the server processes, so that the server processes displayed in the form of a tree are displayed.
The advantage of the Pstree command is that you can immediately find the parent process of a process. You may need to use the-p option to display the PID of each process, and the-u option to display the user name that starts the process.
In general, this tree structure is relatively long, so you need to execute pstree-up | less, which will allow you to view the entire process tree structure.

5. secureCRT garbled solution: Options-> SessionOptions-> Appearance-> font to default into the UTF-8, you can display the Chinese font.
 
6. hostname: Check hostname

7. ifconfig query Host IP Address

8. use ctrl + c and ctrl + v in the S-CRT:
Options --- Global Options --- Edit default Settings, click Terminal --- Emulation, click Mapped Keys, click "use windows copy and paste key", and click "OK.

 

9. Run the following command to access vi:
Vi filename: open or create a file and place the cursor at the beginning of the first line
Vi + n filename: open the file and place the cursor at the beginning of line n
Vi + filename: open the file and place the cursor at the beginning of the last line
Vi +/pattern filename: open the file and place the cursor at the first string matching pattern

10. move the cursor command:
}: Move the cursor to the beginning of the paragraph
{: Move the cursor to the end of the paragraph
NG: move the cursor to the beginning of line n
N +: move the cursor down n rows
N-: Move n rows above the cursor
N $: move the cursor to the end of line n
H: move the cursor to the top line of the screen
M: move the cursor to the middle line of the screen
L: move the cursor to the last line of the screen
0: (Note the number is zero) move the cursor to the beginning of the current row
$: Move the cursor to the end of the current row

11. Screen tumble commands:
Ctrl + u: half screen at the beginning of the file
Ctrl + d: Flip the half screen to the end of the file
Ctrl + f: Flip the screen to the end of the file // It seems to be r
Ctrl + B; open a screen at the beginning of the file
 
12. SEARCH command:
/Pattern: Search for pattern from the beginning of the cursor to the end of the file
? Pattern: Search for pattern from the beginning of the cursor
N: Repeat the previous search command in the same direction.
N: Repeat the previous search command in the reverse direction.

Postgres usage:
1. Enter the SQL running environment.
[Test @ test bin] $./psql-n dbname-U usrname
Stay81 = # select count (*) from table1;
Count
-------
5986
(1 row)

2. Exit. Exit after use. Otherwise, the connection will be suspended.
Stay81 = # \ q

3. postgres data export.
[S @ test bin] $./pg_dump-U postgres-t testTable-d testDB> testTable. dump
Or [S @ test bin] $./pg_dump-U postgres-d testDB-t testTable-F c-v> testTable. dump

4. S data import.
[S @ test bin] $./psql-U postgres-d testDB <testTable. dump
Or [S @ test bin] $./pg_restore-U postgres-d testDB <testTable. dump

5. One host dumps the database directory to another.
Pg_dump-h host1-p 5432 dbname | psql-h host2-p post1 dbname
Or./pg_dump-U postgres-d testDB1-t testTable |./psql-U postgres-d testDB2
-U is the user name,-d is the DB name, and-t is the table name. This option is not required if the entire database is exported.

6. php Execution.
[Test @ test bin] $/usr/bin/php-q./batchstart. php

Practice:
/Home/absys6 $ ls
Dvlp dvlp_bak20090413 personal tmp
/Home/absys6 $ cd dvlp
/Home/absys6/dvlp $ ls
/Home/absys6/dvlp $ cd SV_POLICY
/Home/absys6/dvlp/SV_POLICY $ ls
Include src
/Home/absys6/dvlp/SV_POLICY $ cd src
/Home/absys6/dvlp/SV_POLICY/src $ ls
/Home/absys6/dvlp/SV_POLICY/src $ ls * pc // filter files
/Home/absys6/dvlp/SV_POLICY/src $ grep VIP * pc // code that lists all. pc files containing VIP.
/Home/absys6/dvlp/SV_POLICY/src $ vi PlyPrmCnt. pc // view the entire file.
