But I get: 1 00 00 00 01 8F 09 FE 51 8F 09 FE 51 8F 09 FE 51 8F 09 FE 5C 0 1 00 01 00 01 8F 09 FE 50 00 0A 0E 1F 0F F1 FE 51 4F 09 FE 55 8 I did sed -e 's/../_& /g' And I got: _:1 _00 _00 _00 _01 _8F _09 etc... _:1 _00 _01 _00 _01 _8F _09 etc... which makes sense... but when I try to do just with a space, it fails. >How-To-Repeat: Make a file with this content: :1000000018F09FE518F09FE518F09FE518F09FE5C0 :1000100018F09FE50000A0E1F0FF1FE514F09FE558 or take any intel .hex file, and run " sed 's/../& /' " on it. >Fix: I could not find the problem >Release-Note: >Audit-Trail: >Unformatted:
