android 编译系统阅读与分析(1)-envsetup.sh (editing....)

16lz 2021-01-25

一直想分析一下andoid的整个build系统，苦于菜鸟一个又少有时间，只能蚂蚁搬家似的一点点学，一点点做.....

所谓分析，那是要对结构要有所见解，但因为这样那样的原因，还远没能达到高屋建瓴的水平。所以，得空就学一下linux，

顺便“读”一下有关的android内容，做些笔记。也希望能得到大家的指正，一起进步！～

(sed, awk, cut, wc, bash, gnumake...........RTFM.........~>_<~ )

function help() {
cat <<EOF
Invoke ". build/envsetup.sh" from your shell to add the following functions to your environment:
- croot: Changes directory to the top of the tree.
- m: Makes from the top of the tree.
- mm: Builds all of the modules in the current directory.
- mmm: Builds all of the modules in the supplied directories.
- cgrep: Greps on all local C/C++ files.
- jgrep: Greps on all local Java files.
- resgrep: Greps on all local res/*.xml files.
- godir: Go to the directory containing a file.

Look at the source to view more functions. The complete list is:
