Pipe尾output进列

Question

I'm trying to tail a log file and format the output into columns. This gives me what I want without tail:

cat /var/log/test.log | column -t -s "|"

How can I pipe the output of tail -f var/log/test.log into column ?

EDIT: Here's an excerpt from the file. I'm manually adding the first line of the file so it could be used as the column headers, but I could format it differently if necessary.

timestamp|type|uri|referer|user_id|link|message

You can't do it with the -f option to tail . column can't produce any output until it receives all its input, since it needs to calculate the number of rows and columns by examining all the input. tail -f never stops writing, so column doesn't know when it's done.

You can use

tail -n 100 test.log | column -t -s "|"

to format the last 100 lines of the log.
