pmjson − Performance Co-Pilot JSON dumping utility

SYNOPSIS

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

DESCRIPTION

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

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 superfluous 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 stream.

−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

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