rgb2hexscript

[williams2]

There is a file rgb2hexscript in bionicpup64-8.0

It's possible to use awk to convert numbers to hex.
This should do the same thing as the sh script:

Code: Select all

echo $1 $2 $3 | awk '{printf "%02X%02X%02X\n",$1,$2,$3}'

This allows the script to be used with a pipe:

Code: Select all

#!/bin/ash
if test $# -eq 0
then
  awk '{printf "%02X%02X%02X\n",$1,$2,$3}'
else
  echo $1 $2 $3 | awk '{printf "%02X%02X%02X\n",$1,$2,$3}'
fi

Not a bug.

Possible, but why use awk?

Code: Select all

#!/bin/ash
R=255
G=120
B=10
printf "%02X%02X%02X\n" $R $G $B
