NAME
ts - timestamp input
SYNOPSIS
ts [-r] [-i | -s] [format]
DESCRIPTION
ts adds a timestamp to the beginning of each line of input. The optional format parameter controls how the timestamp is formatted, as used by strftime(3). The default format is "%b %d %H:%M:%S". In addition to the regular strftime conversion specifications, "%.S" and "%.s" are like "%S" and "%s", but provide subsecond resolution (ie, "30.00001" and "1301682593.00001"). If the -r switch is passed, it instead converts existing timestamps in the input to relative times, such as "15m5s ago". Many common timestamp formats are supported. Note that the Time::Duration and Date::Parse perl modules are required for this mode to work. Currently, converting localized dates is not supported. If both -r and a format is passed, the existing timestamps are converted to the specified format. If the -i or -s switch is passed, ts timestamps incrementally instead. In case of -i, every timestamp will be the time elapsed since the last timestamp. In case of -s, the time elapsed since start of the program is used. The default format changes to "%H:%M:%S", and "%.S" and "%.s" can be used as well.
ENVIRONMENT
The standard TZ environment variable controls what time zone dates are assumed to be in, if a timezone is not specified as part of the date.
