NAME         top

       pmjson - Performance Co-Pilot JSON dumping utility

SYNOPSIS         top

       pmjson [-mpqyV?]  [-i infile] [-o outfile]

DESCRIPTION         top

       pmjson is used to manipulate JSON (JavaScript Object Notation)
       formatted text used in the Performance Co-Pilot (PCP toolkit).  It
       can produce minimal and human readable output formats when it is
       supplied with valid JSON input.

OPTIONS         top

       The available command line options are:

       -i infile, --in=infile
            JSON formatted input infile - path to a file from which input
            should be read.  If this option is omitted, then pmjson will
            read from the standard input stream.

       -m, --minimal
            Produce JSON output with all superflous whitespace removed from
            the resulting JSON string.

       -o outfile, --out=outfile
            Formatted output is written to the named outfile.  If this
            option is omitted, then pmjson will write to the standard output

       -p, --pretty
            Produce JSON output in a human-readable format.

       -q, --quiet
            Verify the input as valid JSON only, no output is produced.

       -V, --version
            Display version number and exit.

       -y, --yaml
            Produce YAML-like output, a human-readable format with less
            syntactic sugar than JSON.

       -?, --help
            Display usage message and exit.


       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
       configuration file, as described in pcp.conf(5).
