Another handy option is --om-separator=text (only matching separator) which specifies a separating string. For example, --om-separator=", " separates matches by commas

pcregrep 8.41 (installed with apt-get install pcregrep on Ubuntu 16.03) doesn't recognize the -Ei switch. It works perfectly without it, though. On macOS, with pcregrep installed via homebrew (also 8.41) as @anishpatel mentions above, at least on High Sierra the -E switch is also not recognized.

On macOS, brew install pcre. Also note that Homebrew's zsh depends on pcre, so you may already have pcre if you installed that.

yeah, very help, e.g. echo 'r123456 foo 2016-03-17' | pcregrep -o1 'r([0-9]+)' 123456

@WAF sorry, guess I should have included that info in my comment. I'm on Centos 6.5 and the pcregrep version is apparently very old: 7.8 2008-09-05.

i can't reproduce it. probably the impl of this pcregrep is different. could you provide more info? what about the difference between this and grep -P? not even in man page: linux.die.net/man/1/pcregrep

My pcregrep doesn't seem to understand the digit after the -o: "Unknown option letter '1' in "-o1". Also no mention of that functionaliy when looking at pcregrep --help

pcregrep is not available by default in Mac OS X which is what the OP uses
