NAME

addts − add timestamps at the beginning of each line

SYNOPSIS

addts [−asu] [−f FMT] [−w CHR] [FILE]

addts −?

DESCRIPTION

Reads standard input and writes it to standard output, adding a timestamp at the begginning (or end) of each line. If FILE is suppied, writes to it instead. Typical usage is for Apache forensic log:

ForensicLog "|/usr/bin/addts -a /var/log/httpd/forensic.log"

To add timestamps to the end of each line, formatting it as an additional header:

ForensicLog "|/usr/bin/addts -a -s -f ’|X-TS:%c’ /var/log/httpd/forensic.log"

OPTIONS

−a

Append to FILE. Without this option, FILE is truncated after opening.

−f FMT

Define timestamp format. FMT is a strftime(3) format string, with an additional format conversion specifier %@, which is replaced with micronseconds.

See also −w, below.

−s

Add timestamp to the end of each line (suffix mode).

−u

Report times in UTC.

−w CHR

Replace each occurrense of character CHR in format string with single whitespace. Use this option if your Apache version is unable to correctly process quoted arguments in the ForensicLog statement. Example usage (newlines added for readability):

ForensicLog "|/usr/bin/addts -w_ -f %Y-%m-%d_%H:%M:%S.%@:_ \
              -a /var/log/httpd/forensic.log"

BUGS

Formatted timestamp cannot be longer than 511 bytes.

Empty lines are left unchanged (no timestamp added).

SEE ALSO
