Linux下通過script命令記錄數(shù)據(jù)庫操作教程

  對(duì)DBA而言,經(jīng)常碰到升級(jí)數(shù)據(jù)庫或是apply patch,以及有些時(shí)候需要運(yùn)行大量的腳本。對(duì)于這些操作我們希望現(xiàn)在在屏幕同時(shí)又輸出的文件以備后續(xù)查詢過程中曾經(jīng)丟失的步驟或錯(cuò)誤。接下來是小編為大家收集的Linux下通過script 命令記錄數(shù)據(jù)庫操作教程,希望能幫到大家。

  Linux下通過script 命令記錄數(shù)據(jù)庫操作教程

  1、script命令描述

  復(fù)制代碼

  代碼如下:

  script命令會(huì)記錄所有的操作到文件同時(shí)在屏幕上輸出,直到終止登陸的會(huì)話,或使用CRTL+D,或使用exit退出則停止記錄。

  這個(gè)命令對(duì)于數(shù)據(jù)庫的升級(jí)或是重要設(shè)置的情形下使用可以用于后續(xù)查詢操作成功或失敗。

  用法: $ script [upgrade.log]

  如果未指定日志文件名的情形,自動(dòng)生成日志文件名為typescript。

  如果需要輸出到已經(jīng)存在的日志文件,則使用 -a 參數(shù),再接已經(jīng)存在日志文件名。

  如果需要在輸出到日志文件的同時(shí),也可以查看日志文件的內(nèi)容,可以使用 -f 參數(shù)。

< p># script 幫助描述

  robin@SZDB:~> man script

  NAME

  script - make typescript of terminal session

< p>SYNOPSIS

  script [-a] [-c COMMAND] [-f] [-q] [-t] [file]

< p>DESCRIPTION

  Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of

  an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1).

< p> If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the

  file typescript.

< p> Options: < p> -a Append the output to file or typescript, retaining the prior contents. < p> -c COMMAND

  Run the COMMAND rather than an interactive shell. This makes it easy for a script to capture the output of a pro-

  gram that behaves differently when its stdout is not a tty.

< p> -f Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and

  another can supervise real-time what is being done using `cat foo'.

< p> -q Be quiet. < p> -t Output timeing data to standard error. This data contains two fields, separated by a space. The first field indi-

  cates how much time elapsed since the previous output. The second field indicates how many characters were output

  this time. This information can be used to replay typescripts with realistic typing and output delays.

  2、script命令用法示例

  復(fù)制代碼

  代碼如下:

  a、script命令后接日志文件名

  robin@SZDB:~> script test_logfile.log #啟用script

  Script started, file is test_logfile.log

< p> .................#中間操作省略

  robin@SZDB:~> exit #停止script

  exit

  Script done, file is test_logfile.log

< p>#查看剛剛生成的日志文件

  robin@SZDB:~> more test_logfile.log

  EXIT;

  if [ -z "$RETVAL" ]; then

  echo "No rows returned from database"

  exit 0

  else

  echo $RETVAL
