Hi, I'm writting a simple shell script that can do the following thing:

$strA = abc-def, and my question is how to loop the string till it reaches the " - ", then save the "def" as a new string, $strB = def

Thanks all,

Sun

$ export strA=abc-def
$ echo $strA
abc-def
$ export strB=`echo $strA | cut -d"-" -f2`
$ echo $strB
def

Best regards.

Thanks for your quick replied, Frank!!

May be I didn't state my question clearly in which the $strA could be "abcdef-ghijk" or "abcdefghij-klmnop", etc , so I'm looking for a way that could do some looping till it reaches
" - " ( no idea where the " - " appear on the $strA ), and save whatever comes after " - " into the $strB.

$strA = abcdef-ghijk
$strB = ghijk

or

$strA = abcdefghij-klmnop
$strB = klmnop

Best Regards,

Sun
