Lines: 17 My major concern with the use of 'cat' is the very real possibility of leaving the cat process running if the program terminates on it's own (that is, not due to an end of file from the termination of cat). This can result in strange occurrences where some of your input is taken by the cat process and shipped to nowhere while the rest is taken by the shell. Not so. When the program terminates the 'cat' gets a SIGPIPE signal which kills it off. -- spoken: mark weiser UUCP: {seismo,allegra,brl-bmd}!umcp-cs!mark CSNet: mark@umcp-cs ARPA: mark.umcp-cs@UDel-Relay
