Common SecureCRT commands

Common commands: 1. ls only lists file names (which is equivalent to dir and dir can also be used)-A: lists all files, including hidden files. -L: a list that contains most attributes of a file. -R: recursive display. -- Help: the help of this command. II. change the cd directory cd/: Enter the root directory...

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
Webadmin 421908 368956 0 Sep 24-/usr/java5_64/bin/java-Xms256m-Xmx512m-da-Dplatform. home =/home/weblogic/bea/weblogic92-Dwls. home =/home/weblogic/bea/weblogic92/server-Dwli. home =/home/weblogic/bea/weblogic92/integration-Dweblogic. management. discover = true-Dwlw. iterativeDev = false-Dwlw. testConsole = false-Dwlw. logErrorsToConsole =-Dweblogic. ext. dirs =/home/weblogic/bea/patch_weblogic923/profiles/default/sysext_manifest_classpath-Dweblogic. name = AdminServer-Djava. security. policy =/home/weblogic/bea/weblogic92/server/lib/weblogic. policy weblogic. server

Note: Follow the prompts above to view the processes started by the login user bea2. Note that bea2 marked in red is owned by the process and 491796 is the process number.
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.

 

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