OPENGREP_LOG_FILE

Also spelled

SEMGREP_LOG_FILE

Value

a file path

See also

--debug, --verbose, OPENGREP_LOG_LEVEL

A file that receives a copy of the logs that Opengrep writes to standard error, at the same level. At the default level, these are the warnings and the summary; --verbose, --debug and OPENGREP_LOG_LEVEL raise the level for both. Standard error is not affected.

The file is truncated at the start of each run, and missing directories on its path are created. When the file cannot be created, Opengrep logs the warning cannot write the log file of $OPENGREP_LOG_FILE and runs without it.

## Examples
