How do I insert x'0D' ?

rchuttke · #1 (**permalink**) 03-26-2008

I'm directing output to a *.dat file. The first byte is a variable, the second must be a carriage-return (x'0D'). Is there a UNIX equivalent of an ASCII command that will allow me to output this byte?

Nothing really easy is thoroughly standardized. Most systems these days would come with a printf(1) command. If you want to be 1970s compliant then maybe something like

Code:

echo | tr '\012' '\015'

(In case this is not obvious, a lone echo prints just a newline, and the tr converts it to something else; the codes understood by tr are, regrettably, in octal.)

That did it! Thanks!
