Full Discussion: Parsing and timestamp a pattern in log

It gets tricky when there are adjacent errors, unless you report the time in the middle twice, one at the end of the first and once at the beginning of the second. You could write a pretty simple sed script to pull all the lines from timestamp N to timestamp N+1 into the buffer, check for error and write to output or side file if any, get rid of all but the last line, and loop back to filling the buffer up to the next time stamp.

It would be easy to make the buffer load into one line before writing it out, so they can be handled more simply after.

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.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
