Subject: [PATCH] rpi-eeprom-update: Use 'tr' instead of 'strings'
|
||
|
|
|
||
|
|
The 'strings' utility is installed by binutils whereas 'tr' belongs with
|
||
|
|
coreutils. Minimal systems will only contain the latter, due to binutils'
|
||
|
|
size (20-50 MB). So, convert all uses of 'strings' to 'tr' so as to
|
||
|
|
avoid the package dependency.
|
||
|
|
|
||
|
|
The second and third 'tr' usage converts non-ASCII characters into newlines
|
||
|
|
so as to isolate the "BUILD_TIMESTAMP=1234567890" statement (similar to what
|
||
|
|
'strings' does). There is no need for this in the first one: non-ASCII
|
||
|
|
characters are simply discarded as DT aliases have a fixed one line
|
||
|
|
format.
|
||
|
