bc

Each abuse is GTFOBins's category and the options and words it uses; the full write-up is on GTFOBins's page for bc.

bc -s /path/to/input-file
quit

The command the identifier reads trips no Sigma process-creation rule. This command is, with GTFOBins’ notes, from GTFOBins, at commit acd524623f9c of 2026-05-27, under the GPL-3.0, with no warranty. Changed: Markdown is shown formatted. The source is in lolbas-gtfobins-commands.json.gz, and the full entry is on GTFOBins’s page for bc. The identifier reads the line that runs bc.

None of the 3 examples the identifier reads matches GTFOBins abuse or trips a Sigma process-creation rule.
