1、script命令描述

复制代码代码如下:script命令会记录所有的操作到文件同时在屏幕上输出，直到终止登陆的会话，或使用CRTL+D，或使用exit退出则停止记录。这个命令对于数据库的升级或是重要设置的情形下使用可以用于后续查询操作成功或失败。用法: $ script [upgrade.log]如果未指定日志文件名的情形，自动生成日志文件名为typescript。如果需要输出到已经存在的日志文件，则使用 -a 参数，再接已经存在日志文件名。如果需要在输出到日志文件的同时，也可以查看日志文件的内容，可以使用 -f 参数。</p><p># script 帮助描述robin@SZDB:~> man scriptNAME script - make typescript of terminal session</p><p>SYNOPSIS script [-a] [-c COMMAND] [-f] [-q] [-t] [file]</p><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><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><p> Options:</p><p> -a Append the output to file or typescript, retaining the prior contents.</p><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><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><p> -q Be quiet.</p><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.
