Look-ahead for even number of quotes:

$_ = q[cd / ; /path/to/R/R_latest --vanilla --args "fName='rGSDPlan';j
+obCode=682718;jobId=6827181;" < job682718.R > job_6827181.txt];

say s/;(?=[^"]*(?:"[^"]*"[^"]*)*$)/&&/gr;

Output:

cd / && /path/to/R/R_latest --vanilla --args "fName='rGSDPlan';jobCode
+=682718;jo
bId=6827181;" < job682718.R > job_6827181.txt

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
