在OS X中找不到strtonum [英] strtonum in OS X, not found

问题描述

cmp -l "$1" "$2/$1" | awk '{printf "%08X %02X %02X\n", $1, strtonum(0$2), strtonum(0$3)}'

我正在使用上面的命令从shell脚本显示Ubuntu中的二进制差异.但是，这在OS X lion中不起作用，声称找不到strtonum.知道如何在OS X中使用它或将其替换为类似/轻巧的东西吗?

I am using command above to show the binary differences in Ubuntu, from shell script. However, this doesn't work in OS X lion, claiming that strtonum not found. Any idea how to have it in OS X or substitute it with something similar/light?

推荐答案

MacPorts 或 Homebrew 可用于安装awk的GNU版本，其中包括strtonum.为了避免与系统awk发生冲突，他们将GNU版本安装为gawk.

Either MacPorts or Homebrew can be used to install the GNU version of awk which includes strtonum. To avoid conflicts with the system awk, they install the GNU version as gawk.

例如，安装了基本的MacPorts文件:

For example, with the base MacPorts files installed:

sudo port install gawk
