Description

Function name Description
copy() A function to copy a single file, and give the same permission as the source.
1 つのファイルをコピーする関数．コピー元のファイルと同一のパーミッションを付与します．
cp() A function to copy files and directories, and give the same permission as the source.
複数のファイルやディレクトリをコピーする関数．コピー元のファイルやディレクトリと同一のパーミッションを付与します．

options
- n: (n: no overwrite) do not to overwrite the existing file.
- p: (p: permission) copy file with the same permission and timestamp.
- u: (u: update) update the file only when the dst file is older than src file.

Usage

copy(): copy a file

  • main.cpp 
    #include <sstd/sstd.hpp>

int main(){
    sstd::mkdir("./tmp");
    sstd::system("dd if=/dev/urandom of=./tmp/rand.bin bs=1M count=10 > /dev/null 2>&1");

    sstd::copy("./tmp/rand.bin", "./tmp/rand_copy.bin");
    sstd::system("ls ./tmp");
    sstd::system("sha256sum ./tmp/rand.bin | cut -d \" \" -f 1");
    sstd::system("sha256sum ./tmp/rand_copy.bin | cut -d \" \" -f 1");

    sstd::rm("./tmp");
}
  • Execution result
