CONDOR_TRANSFORM_ADS(1)

NAME
condor_transform_ads - HTCondor Manual

Transform ClassAds according to specified rules, and output the transformed ClassAds.

SYNOPSIS

condor_transform_ads [-help [rules] ]

condor_transform_ads [-rules rules-file] [-jobtransforms name-list] [-jobroute route-name] [-in[:<form>] ** *infile*] [-out[:<form>[, nosort]] ** outfile] [<key>=<value> ] [-long ] [-json ] [-xml ] [-verbose ] [-terse ] [-debug ] [-unit-test ] [-testing ] [-convertoldroutes ] [infile1

Note that one or more transforms must be specified in the form of a rules file or a JOB_TRANSFORM_ or JOB_ROUTER_ROUTE_ name and at least one input file must be specified. Transforms will be applied in the order they are given on the command line. If a rules file has a TRANSFORM statement with arguments it must be the last rules file. If no output file is specified, output will be written to stdout.

DESCRIPTION

condor_transform_ads reads ClassAds from a set of input files, transforms them according to rules defined in a rules files or read from configuration, and outputs the resulting transformed ClassAds.

See the classads/transforms:Classad Transforms section for a description of the transform language.

OPTIONS

-help [rules | convert]
    Display usage information and exit. -help rules displays information about the available transformation rules. -help convert displays information about the -convertoldroutes option.

-rules rules-file
    Specifies the file containing definitions of the transformation rules, or configuration that declares a JOB_TRANSFORM_<name> or JOB_ROUTER_ROUTE_<name> variable for use in a subsequent -jobtransforms <name> or -jobroute <name> argument.

-jobtransforms name-list
    A comma-separated list of more transform names. The transform rules will be read from a previous rules file or the configured JOB_TRANSFORM_<name> values

-jobroute name
    A job route. The transform rules will be read from a previous rules file or the configured JOB_ROUTER_ROUTE_<name> values

-in[:<form>] infile
    Specifies an input file containing ClassAd(s) to be transformed. <form>, if specified, is one of:

•   long: traditional long form (default)

•   xml: XML form

•   json: JSON ClassAd form

•   new: "new" ClassAd form without newlines

•   auto: guess format by reading the input
    If - is specified for infile, input is read from stdin.

-out[:<form>[, nosort] outfile
    Specifies an output file to receive the transformed ClassAd(s). <form>, if specified, is one of:

•   long: traditional long form (default)

•   xml: XML form

•   json: JSON ClassAd form

•   new: "new" ClassAd form without newlines

•   auto: use the same format as the first input
    ClassAds are storted by attribute unless nosort is specified.

[<key>=<value> ]
    Assign key/value pairs before rules file is parsed; can be used to pass arguments to rules. (More detail needed here.)

-long
    Use long form for both input and output ClassAd(s). (This is the default.)

-json
    Use JSON form for both input and output ClassAd(s).

-xml
    Use XML form for both input and output ClassAd(s).

-verbose
    Verbose mode, echo to stderr the transform names as they are applied and individual transform rules as they are executed.

-terse
    Disable the -verbose option.

-debug
    Causes debugging information to be sent to stderr, based on the value of the configuration variable TOOL_DEBUG.

EXIT STATUS

condor_transform_ads will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.

EXAMPLES

Here's a simple example that transforms the given input ClassAds according to the given rules: Input file (my_input).INDENT 0.0

# File: my_input
ResidentSetSize = 500
DiskUsage = 2500000
NumCkpts = 0
TransferrErr = false
Err = "/dev/null"
Rules file (my_rules).INDENT 0.0

# File: my_rules
EVALSET MemoryUsage ( ResidentSetSize / 100 )
EVALMACRO WantDisk = ( DiskUsage * 2 )
SET RequestDisk ( $(WantDisk) / 1024 )
RENAME NumCkpts NumCheckPoints
DELETE /(.+)Err/
Command execution.INDENT 0.0

$ condor_transform_ads -rules my_rules -in my_input
Resulting ClassAd output.INDENT 0.0

DiskUsage = 2500000
Err = "/dev/null"
MemoryUsage = 5
NumCheckPoints = 0
RequestDisk = ( 5000000 / 1024 )
ResidentSetSize = 500
