What I did were as follows step by step:
Git clone go-ethereum project to my local PC. It is located in D:\GOPATH\src\github.com\ethereum\go-ethereum. It is the source code of go-ethereum
Note: The OS is windows 7. Go has already been installed. And GOPATH env has already been set to "D:\GOPATH"
cd /d D:\GOPATH\src\github.com\ethereum\go-ethereum. Then execute "go install". Some exe files were genereated under D:\GOPATH\bin directory, and many pkg file with suffix .a were generated under D:\GOPATH\pkg directory. Everything seems no problem.
- Execute "go clean -n -r -i github.com/ethereum/go-ethereum..." to remove all the generated exe files and .a files. But something very interesting happened:
In the command's log, it showed that some files are deleted, but actually they are not deleted from disk.
For example, event.a exists under D:\GOPATH\pkg\windows_amd64\github.com\ethereum\go-ethereum, but the log of "git clean" shows:"rm -f D:\GOPATH\pkg\windows_amd64\github.com\ethereum\go-ethereum\event.a"
The detailed information is in the attached images.
It is very strange. The log does not match with the actual result:
A small segment of go clean command is as follows(since there are more than 1300 lines in log, I can not paste all of it):
cd D:\GOPATH\src\github.com\ethereum\go-ethereum\event
rm -f event.test event.test.exe
rm -f D:\GOPATH\pkg\windows_amd64\github.com\ethereum\go-ethereum\event.a
cd D:\GOPATH\src\github.com\ethereum\go-ethereum\common\mclock
rm -f mclock.test mclock.test.exe
rm -f D:\GOPATH\pkg\windows_amd64\github.com\ethereum\go-ethereum\common\mclock.a
cd D:\GOPATH\src\github.com\ethereum\go-ethereum\vendor\github.com\aristanetworks\goarista\monotime
rm -f monotime.test monotime.test.exe
rm -f D:\GOPATH\pkg\windows_amd64\github.com\ethereum\go-ethereum\vendor\github.com\aristanetworks\goarista\monotime.a
cd D:\GOPATH\src\github.com\ethereum\go-ethereum\accounts\abi
rm -f abi.test abi.test.exe
rm -f D:\GOPATH\pkg\windows_amd64\github.com\ethereum\go-ethereum\accounts\abi.a
cd D:\GOPATH\src\github.com\ethereum\go-ethereum\accounts\abi\bind
rm -f bind.test bind.test.exe
rm -f D:\GOPATH\pkg\windows_amd64\github.com\ethereum\go-ethereum\accounts\abi\bind.a
But some of the files remain:
