Please wrap your code/format-sensitive text in
<code> tags so that we can read it. For everyone else's benefit:
------file
vegeta-44
matriz-22
evac-500
fritzilldo-200
teenreality-15
------------
Something simple like this might work for you:
perl -pi.bak -e 's/(?<=vegeta-)(\d+)/$1 + 6/e' memberpoints.txt
I might suggest that you put your data in a "real" data format, such as via
dbmopen or
tie a
DB_File to a hash. Then your changes could be as simple as:
$hash{vegeta} += 6;
Likewise, a
CSV file with
DBD::CSV could be updated with a simple
DBI 'update'.
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.
