Thanks.
I am writing a shell script, which will not accept any arguments. But
in this xcript, i want to run a command with many arguments, such as
send the same mail to many peope:
"mail person1@site1 person2@sit2 person3@site3 ...... < mymail"
I am wondering how many addresses i can give to mail, which is related
to the max command line legth.
According to what you said, in this situation the limit is 128K?
Do you think so?
