Re: Including a simple regex with -param
Use single quotes around the param value so that shell does not interpret the "|" . (in case of bash shell)

$ cat t.pig
matches '.*\\b($keyword)\\b.*';

$ java -Xmx500m -cp pig.jar org.apache.pig.Main -dryrun -x local        -param keyword='abc|def' t.pig

I'm having trouble finding a way to include a simple regex string with the -param flag.

Example: pig -f myscript.pig -param keyword=buy|price|sell|sale|discounts

I've tried a mix of quotes, escapes, etc and nothing seems to work. The corresponding line in my pig script looks something like

matches '.*\\b($keyword)\\b.*';

Any help or comments would be appreciated.
