Does SEDCMD use PCRE regular expressions?

Question

I know that in general, regular expressions in Splunk use PCRE (or a modified PCRE for matching in props.conf source stanza headings). If I set SEDCMD in props.conf, e.g.:

SEDCMD-example = s/regex/subst/g

is the regex also PCRE? Standard sed uses grep or egrep regexes, not PCRE, so this isn't entirely clear.

Accepted Answer

SEDCMD uses PCRE regex and thus is equivalent to sed -r

props.conf.spec
SEDCMD-<class> = <sed script>
....
* Syntax:
 * replace    - s/regex/replacement/flags
  * where regex is a perl regex (optionally containing capturing groups)
  * replacement is a string to replace the regex match, use \N for backreferences
  * flags can be either: g to replace all matches or a number to replace a specified match
 * substitute - y/string1/string2/
  * substitutes the string1[i] with string2[i]
