echo --version

[download]
output 
--version

[download]
input 
code="\tcode"
echo $code

[download]
output 
tcode

instead of the version details and also \n\a\c\b\x are not working well right now i am reading shell scripting so is this book too old and amendments are made in shell script? or am i doing something wrong

In reply to OT: unable to use the options of echo in my shell terminal bash ofcourse by ramachandrajr
