pmjson - Performance Co-Pilot JSON dumping utility
pmjson [
-mpqyV?] [
-i infile] [
-o
outfile]
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.
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 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
- 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).
PMWEBAPI(3),
pcp.conf(5) and
pcp.env(5).
