condor_transform_ads man page

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

Synopsis

condor_transform_ads [ -help [rules] ]

condor_transform_ads -rules rules-file [ -in[:<form>] infile ] [ -out[:<form>[, nosort]] outfile ] [ <key>=<value> ] [ -long ] [ -json ] [ -xml ] [ -verbose ] [ -terse ] [ -debug ] [ -unit-test ] [ -testing ] [ -convertoldroutes ] [ infile1 ...infileN ]

Note that exactly one rules file, and at least one input file, must be specified. 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 file, and outputs the resulting transformed ClassAds.

See https://htcondor-wiki.cs.wisc.edu/index.cgi/wiki?p=TjsAdTransformLanguagefor a description of the transform language.

Options

-help [rules]
Display usage information and exit. -help rules displays information about the available transformation rules.
-rules rules-file
Specifies the file containing definitions of the transformation rules.
-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 transform rules as they are executed.

-terse

Disable the -verbose option.

-debug

More information needed here.

-unit-test

More information needed here.

-testing

More information needed here.

-convertoldroutes

More information needed here.

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:

 # File: my_input
 ResidentSetSize = 500
 DiskUsage = 2500000
 NumCkpts = 0
 TransferrErr = false
 Err = "/dev/null"

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

 # Command:
 condor_transform_ads -rules my_rules -in my_input

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