I'm new to Unix and have bought today a copy of "The Unix Programming Environment". I'm trying out the stuff from the book. But some of them are not working as expected like : To kill a line and re-type it again, @ character should be used :
book
$ ddtae@
date
Thu Nov 28 18:12:47 IST 2013
my terminal
$ ddtae@
ddtae@: command not found
Another example is to use # to erase last character
book
$ dd#att#e#e
which comes out as date and print it.
my terminal
$ dd#att#e#e
dd#att#e#e: command not found
in my system # is used for commment
Although they have mentioned that these characters are system dependent. How can i find the characters for my system to perform above two tasks.
