Grep Log Files for a Pattern

Crawls through log files and reports jobs with lines matching the pattern. See showLog for an example.

grepLogs(
  ids = NULL,
  pattern,
  ignore.case = FALSE,
  fixed = FALSE,
  reg = getDefaultRegistry()
)

`ids`	[`data.frame` or `integer`] A `data.frame` (or `data.table`) with a column named “job.id”. Alternatively, you may also pass a vector of integerish job ids. If not set, defaults to the return value of `findStarted`. Invalid ids are ignored.
`pattern`	[`character(1L)`] Regular expression or string (see `fixed`).
`ignore.case`	[`logical(1L)`] If `TRUE` the match will be performed case insensitively.
`fixed`	[`logical(1L)`] If `FALSE` (default), `pattern` is a regular expression and a fixed string otherwise.
`reg`	[`Registry`] Registry. If not explicitly passed, uses the default registry (see `setDefaultRegistry`).

[data.table] with columns “job.id” and “message”.
