How to strip extra characters off of a string

I need to be able to just extract the number that is right Under blocks in this example it is the number 57070. This was generated by the quota -g groupname command. Disk quotas for group site53 (gid 165): Filesystem blocks quota limit grace files quota limit grace /dev/hda4 57070 307201 307200 1146 0 0 I have tried using some of the string functions like I used $test=strstr ($test, "hda"); $test= substr("$test",7); This well get me up to the start of the number but now I need to get read of every thing after the number. Is there a better way of getting this info or for striping all the other stuff away. -- Best regards, rdkurth mailto:rdkurth@starband.net
