hi,

i have powershell script returns series of strings variables such as:

sql-instance1-<some more text>

sql-instance2-<some more text>

sql-instance3-<some more text>

i want pass of string to, not including last hyphen new variable, trim off <some more text> part, so for example the value of variables 'sql-instance1',  'sql-instance2' , 'sql-instance3'

i have used lastindex of return values after last hyphen struggling returning values last hyphen.
