The shell traverses the folder and executes the command

Background:

There is a source package that contains many subdirectories and makefile, and the packed package is too large to be deleted and then packaged by all the binaries created by make.

Demand:

Therefore, make clean is required to clear all the target files in all the recursive subdirectories of the catalog.

Code:

Wrote a simple shell script with two features:

1. Traverse all subdirectories and execute make clean if there is makefile (more can be done, of course);

2. list files in all subdirectories that are larger than 10M (and of course you can specify other values).

Words not much to say on the code:

#!/bin/Bashrun_make () {#如果该目录下存在Makefileif[-F"Makefile"]; Then            Echo ""            Echo===================== FOUND ===================pwd; Echo=============================================== MakeClean ; fi}run_ls () {pwd; #列出大于10M的文件 #ls-L |awk '{if ($ > 10485760) {print $}}'        ls-L |awk '{if ($ > 10485760) {print "--", $9,$5}}'                Echo ""}myfunc () {CD $1;        #run_make;        Run_ls;  forXinch$(ls .)
