suspect that this is simple but will ask anyway. I have a client that has a problem with their ISDN and we want to keep the connection alive - so we would probably want to ping an internet address once every 30 seconds. I read man ping and found that I can ping address -i30 -q but I want that process in the background so I get a shell prompt so I add an ampersand to the line to make it... ping (address) -i30 -q & but it still doesn't return to the shell prompt unless I hit return a second time - why? can anyone clue in the clueless? Is this a reasonable way to do this? ----:----|----:----|----:----|----:----|----:----|----:----| - Craig White - PO Box 8634 - Scottsdale, Arizona - 85252 - e-mail address ................ - CraigWhite@AzApple.com - world wide web address ........ - http://www.AzApple.com - e-mail my pager address ....... - 6023779752@airtouch.net - cellular phone ................ - (602) 377-9752 - voice/facsimile ............... - (480) 945-8445 ----:----|----:----|----:----|----:----|----:----|----:----|
