I am working with car radio. OS here is QNX, and command set is very limited: enter image description here

I need to modify file in HEX. I've found sed command, which can do it, but as I've tried to use it, I've stuck.

I need to replace this byte order: 8A 00 00 0A B8 90 4B to -> 8A 00 00 1A B8 90 4B and I have no luck. I have found some codes on stackoverflow like sed ':a;N;$!ba;s/\n//g' file which removes 0A, so maybe possible to remove and append 1A. Are there any chances? Thanks in advance.

newline sed command replace

You were already very close. With GNU sed:

sed ':a;N;$!ba;s/\n/\x1A/g' file

or

sed ':a;N;$!ba;s/\x0a/\x1A/g' file
