Fail on alpine 9 (Docker - Chrominum)

[mnadeau2]

When running in Docker using Alpine 9 image, the chrome-finder fail by expecting a parameter not available in grep. (See official Chrome puppeter documentation for example image). The current work around is to detect docker/unsupported grep and conditionnaly use chrome-finder (not ideal)

The following code:
const chromeFinder = require("chrome-finder"); chromeExecutablePath = chromeFinder();
fail with an exception and console ouput:
`
grep: unrecognized option: R
BusyBox v1.26.2 (2018-05-30 13:51:20 GMT) multi-call binary.

Usage: grep [-HhnlLoqvsriwFE] [-m N] [-A/B/C N] PATTERN/-e PATTERN.../-f FILE [FILE]...

Search for PATTERN in FILEs (or stdin)

    -H      Add 'filename:' prefix
    -h      Do not add 'filename:' prefix
    -n      Add 'line_no:' prefix
    -l      Show only names of files that match
    -L      Show only names of files that don't match
    -c      Show only count of matching lines
    -o      Show only the matching part of line
    -q      Quiet. Return 0 if PATTERN is found, 1 otherwise
    -v      Select non-matching lines
    -s      Suppress open and read errors
    -r      Recurse
    -i      Ignore case
    -w      Match whole words only
    -x      Match whole lines only
    -F      PATTERN is a literal (not regexp)
    -E      PATTERN is an extended regexp
    -m N    Match up to N times per file
    -A N    Print N lines of trailing context
    -B N    Print N lines of leading context
    -C N    Same as '-A N -B N'
