busybox hexdump -R hack

[Pascal Bellard]

Hello,

Please find attached a patch to add 'hexdump -R' a non-standard switch.
It does the reverse of 'hexdump -Cv' ie :
$ hexdump -Cv file.bin > file.ascii
$ hexdump -R file.ascii > file.bin

Usefull to 'edit' binary files with an ascii editor or sed, awk...

Hope it helps,

-pascal
