Publish or Perish command line tools

Overview of the command line version of Publish or Perish

For command line use and advanced users only we provide an edition of the Publish or Perish software that can be used in manual and automated scenarios to perform publication searches.

The use of this software edition requires that you are familiar with command line use on the platform of your choice, in particular with the applicable rules for the quoting of meta characters and other text that has special meaning to the command shell. (If that doesn't mean anything to you, then please use the GUI version of Publish or Perish.)

Note: In contrast to the GUI edition, the command line tool does not have the ability to display Google Scholar CAPTCHAs. If you perform too many queries and Google Scholar requires you to solve a CAPTCHA, the command line search will simply terminate. If that happens, start the GUI edition of Publish or Perish and perform a Google Scholar search to trigger and solve the CAPTCHA, then exit the GUI edition and retry the command line search.

Configuration

Some data sources, for example Microsoft Academic and Scopus, require an API key for their use. The command line edition of Publish or Perish uses the same configuration settings as the GUI edition, so we recommend that you use the GUI version of Publish or Perish to set up the desired API keys before using the command line edition.

If there is no GUI edition of Publish or Perish for your platform, then you can copy the settings.json file from another platform; the configuration settings are platform-independent.

Use the pop8query --info command to see where the settings.json file is stored for the command line tool (and the GUI edition, if any).

Syntax

  • pop8query --help
  • pop8query --info [--all|datasource] [outfile]
  • pop8query options [datasource] [outfile]

With --help the program prints a syntax summary, then exits; no search is performed.

With --info the program prints its configuration information, then exits; no search is performed. By default only version and path information are included; to see data source settings, use --all for all data sources or specify a data source (see next) to see information about that data source only.

Without either --help or --info a publication search is performed. By default Google Scholar is used as the data source, but you can specify another data source through the following data source options:

--crossref
Crossref search
--gsauthor
Google Scholar Profile author search
--gscholar
Google Scholar search
--gsciting
Google Scholar citing references search
--gsprofile
Google Scholar Profile retrieval
--masv2
Microsoft Academic v2 search
--openalex
OpenAlex search
--pubmed
PubMed search
--scopus
Scopus search
--semscholar
Semantic Scholar search
--wos
Web of Science search

After the publication search the results are optionally sorted, then written to outfile if specified, else to stdout. Any diagnostic information and all progress information is written to stderr, so you can redirect them separately if desired.

The data output format is the first of:

  1. the format specified by the --format option (see below)
  2. the extension of outfile, if any:
    .csv   CSV (comma-separated values)
    .json  JSON (JavaScript object notation)
    .jsonl  JSON Lines (JSON with 1 whole record per line)
    .rtf   RTF (full search report as Rich Text)
    .tsv   TSV (tab-separated values)
  3. the default, which is currently CSV output.

For publication searches, the following query field options are available. Please note that:

  • Not all data sources support all query fields. Unsupported fields are reported, but otherwise ignored.
  • The per-field syntax is similar to the one used in the GUI edition and may include "quotes" and boolean operators such as AND and OR -- but see the next point.
  • If entered on a shell command line (as opposed to a programmatically constructed command line or an argument file used with the -f option, below) you may have to use additional quoting to prevent the shell from eating or misinterpreting "quotes" or other special characters. The details depend on the shell in question, but for most shells enclosing the entire field expression (but not the --option itself) in an additional set of 'single' quotes will be sufficient.

Query fields:

--affiliation affiliation
Specify the author affiliation(s) for which to search. This is not widely supported.
--author authorspec
Specify the author(s) for which to search.
--citedid identifier
Specify the data source's document ID for the document that you want to retrieve the citing references for. This is currently only supported for --gsciting
--field fieldofstudy
Specify the field(s) of study for which to search. This is not widely supported and the field names are often idiosyncratic.
--issn issn
Specify the ISSN for which to search.
--journal journalname
Specify the journal(s) for which to search.
--keywords words
Specify the keyword(s) for which to search; these may occur in the abstract, full text, or even (also) in the title; the details depend on the data source.
--raw syntax
Use syntax verbatim for the query; if this options is used, all other query fields are ignored. The syntax must fit the data source in question.
--title words
Specify the title word(s) for which to search.
--years from-to
Specify the first and last years of the publications in which you are interested.

Executive options:

--direct
Bypass the Publish or Perish cache and submit the query directly to the data source, even if the query would otherwise be satisfied from the cache.
--dryrun
Perform all actions except submitting the query to the data source. This is useful to check that the configuration is correct.
-f argfile
Read additional options from argfile (one option per line) and process them at that point of the command line. This allows more complicated options to be specified without additional quoting and also allows annotation of options with comments (comment lines start with a # character). Note that you must use an equals sign '=' between the option name and its value when specifying options in the file (this is also allowed, but not required, on the command line). Example file contents:
# This is a comment
--author="a harzing" AND "d adams"
--keywords=publish perish
--years=2000-2018
--max number
Retrieve no more than number results, even if more would be available.
Note: Because of the granularity of the request size (typically 10, 20, or 100, depending on the data source), the final number of results may be rounded up to the next multiple of the request size.
--maxage hours
Submit the query directly to the data source if the query's cached data are older than hours hours. This overrides the builtin cache period.
--syntax
Create an appropriate query, then print the resulting query syntax as it would be sent to the data source. No query is actually submitted.
Note: Some data sources treat year ranges as a separate filtering option instead of a query field. The value of the --years option may therefore be missing from the query syntax; this does not mean that it was somehow "forgotten". It just means that it is a non-syntax parameter for the data source in question.
--wait secs
Pause for secs seconds between query requests. This is a simple form of rate limiting and is mainly useful to spread the requests over a longer period than Publish or Perish's builtin adaptive rate limiter would do.

Output options:

--append
Append to 'outfile' instead of overwriting. This is useful to collate the output of several separate batch searches into a single file, but is less appropriate for some forms of output, such as rich text (RTF) search reports, that each contain their own document headers and trailers.
--format apa|bibtex|chicago|csiro|csv|harvard|isi|json|jsonl|mla|ris|rtf|rtfshort|tsv|vancouver
Write the results in the given format. This overrides the default or implied (through the extension of outfile, if any) data format. For further processing the json format is recommended, because that contains the most complete information available.
--sort [-]author|title|source|year|cites|cites_annual|cites_norm|rank
Sort the output in ascending or descending (if prefixed with '-') according to the given field. The default results order is rank because that is simply the order in which the results are returned by the data source.

Miscellaneous options:

--help
Print a syntax summary and exit the program with exit code 0.
--version
Print the program's version and exit the program with exit code 0.

Exit codes

The program returns one of the following exit codes:

0
Success: one or more matches for the query. If --info is specified, this exit code merely means "no errors".
1
An error occurred in the command line parameters or in the program execution generally.
2
Syntax error in the query parameters; this includes missing or empty query fields (but not unsupported fields -- those are simply ignored without generating an error code).
3
The query could not be executed, for example because the data source was unavailable.
4
The query returned no matches.

Support Publish or Perish

The development of the Publish or Perish software is a volunteering effort that has been ongoing since 2006. Download and use of Publish or Perish is and will remain free (gratis), but your support toward the costs of hosting, bandwidth, and software development are appreciated. Your support helps further development of Publish or Perish for new data sources and additional features.
