see the following regular expression. Code:
if ( $val =~ m/[,]/) [or] Code:
if ( $val =~ m%,%) you can change the delimiter instead of "/" like %, #, !, | etc., Last edited by ungalnanban; 03-16-2010 at 06:53 AM.. |

what about with a grep if Code:
sample="hello,fool" then Code:
echo "$sample" | grep -c "," returns 1 while Code:
sample1="not here" echo "$sample1" | grep -c "," returns 0 and the result could be put to a variable. |
