Remove Last Character in String Variable

[Michael42]

Hello,

On a Sun Solaris 8 system in a Bourne shell script I have a variable with a string. This string is made up of items that are comma delimited (ITEMS="item1,item2,item3," etc.). The last entry always has a comma.

In my ITEMS string variable, how can I get rid of the last comma?

Thanks,

Michael42

ITEMS=`expr "$ITEMS" : '\(.*\).$'`

Hope This Helps, PH.

The $ isn't really needed for expr in this case.
