将linux日志转换为csv

Question

I'm newbie on linux. I'm so sorry for asking this question again. But I am really appreciate if someone could help me on this. I have trouble on how to convert my linux log to csv file for more readable.

I have apache log as bellow:

[Sun Mar 01 06:01:30 2015] [error] [client 123.456.789.012] File does not exist: /var/www/html/

How can I separate them by column, using: Date ( Sun Mar 01 06:01:30 2015 ), IP ( 123.456.789.012 ) only IP, Error Message ( File does not exist ) and Target ( /var/www/html/ )?

Thank you

There are many ways t achieve it in shell script. Will describe the method in detail and will give a sample example.

You have to identify the delimiter to partition your string and either you can use awk or sed command to partition the fields according to the delimiter

For example in you case you can consider ']' as delimiter s to break the line using the delimiter command will be as follows:

cat logfile | awk -F']' '{print "$1, $2, $3"}' > new_log_file.csv
