How to record operation logs on linux Terminals

How to record the operation logs under linux terminal-Linux general technology-Linux programming and kernel information, the following is a detailed description. On a linux terminal, we can record operation logs to facilitate the check of possible errors and avoid screen scrolling restrictions. Commonly used tools include screen, script, and tee.

1. screen -- screen manager with VT100/ANSI terminal emulatio

> Screen-L
Here is our operation
> Exit
A file name like this will be generated after the end: screenlog.0
> More screenlog.0
In this way, you can view the operations you just performed and find possible problems.

2. script -- make typescript of terminal session

> Script
Our operations
> Exit
Generate a file like this: typescript
> More typescript

3. tee -- read from standard input and write to standard output and files

This command can read the terminal input and output to the terminal or file. Sometimes it can be used to record the possible output of make and other commands to a large amount of content output to the terminal to the file. This allows you to easily record the logs of these commands.

> Make 2> & 1 | tee make. log
Of course, we can also directly redirect to a file.
> Make. log

PS: 2> & 1 is used to record error logs
If you want to filter the control symbols, try to use the "col" command like this:

$ Cat screenlog.0 | col-B> screenlog

Or

$ Cat typescript | col-B> scriptlog
