hi, thanks to all for your replies, i understand the principle if IFS if not the implementation jipe! and your addition below david explains all the 'bad interpreter' errors! all said i can see that my only book on shell programming is woefully basic, so, i went into waterstones today to see what they had, not a lot, and my acid test of looking IFS up in the index to see what it could tell me failed in all of them, i was rather hoping there would be an o'reilly book but i couldn't find one, what would people recommend? amazon list an o'reilly book devoted just to bash, can one fill a book about bash without discussing a lot about programming? would this be a good choice? i welcome peoples advice on reading matter, online docs are all very well but i do like a proper book and also i can take a book to work but not my computer! bascule On Saturday 15 September 2001 6:39 am, you wrote: > Hi, > > I forgot to add, you have to put: > > #!/path/to/perl > > as the first line of the script I posted; (on standard mandrake 8 install, > that would be #!/usr/bin/perl) �also "chmod +x scriptname" without quotes. > > David Charles
