How do I pass hex characters to printf in a script command?
How do I get printf to output hex characters when run from a script?
Suppose I am at the prompt and type printf "x41x42" the output I get
AB%
However if I have a script containing that line i.e. cat test.sh produces
printf "x41x42"
But executing the script ./test.sh produces
x41x42%
How do I get the script to produce the same results as from the shell prompt?
Try using the external printf utility:
/usr/bin/printf "x41x42"
You have probably have a bash shell but as your interactive shell, while sh is linked to dash.
The dash built-in printf doesn’t know xNN, so you have to use octal values, NN, instead.
