pmdate - display an offset date SYNOPSIS
pmdate [ offset ... ] format DESCRIPTION
pmdate displays the current date and/or time, with an optional offset. An offset is specified with a leading sign (``+'' or ``-''), followed by an integer value, followed by one of the following ``scale'' spec- ifiers; S seconds M minutes H hours d days m months y years The output format follows the same rules as for date(1) and strftime(3). For example, the following will display the date a week ago as DDMMYYYY; pmdate -7d %d%m%Y PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura- tion file, as described in pcp.conf(5). SEE ALSO
date(1), strftime(3), pcp.conf(5) and pcp.env(5). Performance Co-Pilot PCP PMDATE(1)
