stripchart - draws diagrams from data with PHP SYNOPSIS
The script is expected to be called as a CGI script but also works from the command line. DESCRIPTION
Stripchart prepares a series of diagrams directly from raw data. It is handy for web pages that need some graphics without too much over- head. OPTIONS
-i input FILE name of input data file (mandatory) -o output FILE name of output .gif file (default: STDOUT) -O output FILE name of output .gif file, also dumps to STDOUT -f from TIME stripchart with data starting at TIME (default: 24 hours ago) -t to TIME stripchart with data ending at TIME (default: now) -r range RANGE stripchart data centered around "from" time the size of RANGE (overrides -t) -l last LINES stripchart last number of LINES in data file (overrides -f and -t and -r) -T title TITLE title to put on graphic (default: FILE RANGE) -x column X time or "x" column (default: 2) -y column Y value or "y" column (default: 3) -Y column Y' overplot second "y" column (default: none) -b baseline VALUE overplot baseline of arbitrary value VALUE -B baseline-avg overrides -b, it plots baseline of computed average -d dump low VALUE ignore data less than VALUE -D dump high VALUE ignore data higher than VALUE -v verbose puts verbose runtime output to STDERR -L log makes y axis log scale -c colors "COLORS" set gnuplot colors for graph/axisnts/data (default: "xffffff x000000 xc0c0c0 x00a000 x0000a0 x2020c0" in order: bground, axisnts, grids, pointcolor1,2,3) -C cgi output CGI header to STDOUT if being called as CGI -s stats turn extra plot stats on (current, avg, min, max) -j julian times time columns is in local julian date (legacy stuff) -V version print version number and exit -h help display this help NOTES
* TIME either unix date, julian date, or civil date in the form: YYYY:MM:DD:HH:MM (year, month, day, hour, minute) If you enter something with colons, it assumes it is civil date If you have a decimal point, it assumes it is julian date If it is an integer, it assumes it is unix date (epoch seconds) If it is a negative number, it is in decimal days from current time (i.e. -2.5 = two and a half days ago) * All times on command line are assumed to be "local" times * All times in the data file must be in unix date (epoch seconds) * RANGE is given in decimal days (i.e. 1.25 = 1 day, 6 hours) * if LINES == 0, (i.e. -l 0) then the whole data file is read in * columns (given with -x, -y, -Y flags) start at 1 * titles given with -T can contain the following key words which will be converted: FILE - basename of input file RANGE - pretty civil date range (in local time zone) the default title is: FILE RANGE AUTHORS

date(1) General Commands Manual date(1) Name date - print date and time Syntax date [-c | -u] [ +format ] [[yy[mm[dd]]]hhmm[.ss][-[-]tttt][z]] Description If no argument is given, or if the argument begins with +, the current date and time are printed. Otherwise, the current date is set. The first mm is the month number; dd is the day number in the month; hh is the hour number (24 hour clock); the second mm is the minute number; .ss the second; -[-]tttt is the minutes west of Greenwich; a positive number means your time zone is west of Greenwich (for example, North and South America) and a negative number means it is east of Greenwich (for example Europe); z is a one letter code indicating the dst cor- rection mode (n=none, u=usa, a=australian, w=western europe, m=middle europe, e=eastern europe); yy is the last 2 digits of the year number and is optional. The following example sets the date to Oct 8, 12:45 AM: date 10080045 The current year is the default if no year is mentioned. The system operates in GMT. The takes care of the conversion to and from local standard and daylight time. If the argument begins with +, the output of is under the control of the user. The format for the output is similar to that of the first argument to All output fields are of fixed size (zero padded if necessary). Each field descriptor is preceded by % and is replaced in the output by its corresponding value. A single % is encoded by %%. All other characters are copied to the output without change. The string is always terminated with a new-line character. Options -c Perform operations using Coordinated Universal Time (UCT) instead of the default local time. The UCT does not use leap seconds so UCT is the same as GMT. -u Perform operations using Greenwich Mean Time (GMT) instead of the default local time. + format The following is a list of field Descriptors that can be used in the format (Note: date exits after processing format information) : %a Locale's abbreviated weekday name %A Locale's full weekday name %b Locale's abbreviated month name %B Locale's full month name %c Locale's date and time representation %d Day of month as a decimal number (01-31) %D Date (%m/%d/%y) %h Locale's abbreviated month name %H Hour as a decimal number (00-23) %I Hour as a decimal number (01-12) %j Day of year (001-366) %m Number of month (01-12) %M Minute number (00-59) %n Newline character %p Locale's equivalent to AM or PM %r Time in AM/PM notation %S Second number (00-59) %t Tab character %T Time (%H/%M/%S) %U Week number (00-53), Sunday as first day of week %w Weekday number (0[Sunday]-6) %W Week number (00-53), Monday as first day of week %x Locale's date representation %X Locale's time representation %y Year without century (00-99) %Y Year with century %Z Timezone name, no characters if no timezone %% % Examples The following command line date +%m/%d/%y generates the following output 04/02/89 The following command line date +"DATE: %m/%d/%y%nTIME: %H:%M:%S" generates the following output DATE: 04/02/89 TIME: 14:45:05 The quotes (") are necessary because the format contains blank characters. Use single quotes (') to prevent interpretation by the shell. Diagnostics Failed to set date: Not owner You are not the super-user and you tryed to change the date. Do not change the date while the system is running in multiuser mode. Restrictions An attempt to set a date to before 1/1/1970 will result in the date being set to 1/1/1970. Files /dev/kmem date(1)
