I want to put `tail -f filename | grep -i -E 'error|warning'` into a variable and construct an e-mail that report any lines that contain "error" or "warning", after that, I will send the mail to the address specified in the RECIPIENT shell variable which is defined within the script.
I have tried `tail -f filename | grep -i -E 'error|warning'` in the terminal, there is no problem that it displayed last(sorry it is not the 'first' I just posted) 10 lines of the file which contain "error" and "warning" firstly, and then wait for the file to grow and check the next line if it is contain the keywords.
also , the `grep -i -E 'error|warning'`, is it correct that it can grep all the "error" or "warning" in any combination of upper and lower case letters?
Thanks!

NAME
script - make record of a terminal session
SYNOPSIS
script [-a] [filename]
DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
record is saved in the file typescript. See WARNINGS.
The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
when the forked shell exits or when Control-d is typed.
OPTIONS
The following option is supported:
-a Appends the session record to filename, rather than overwriting it.
NOTES
script places everything that appears on the screen in filename, including prompts.

privileged user, that is, root. Be sure that typescript is not a link before running script.
