[Linux指令] 如何抓取FTP目錄下的資料夾

Linux下的 ftp 工具可以用 mget 來抓取複數檔案,但是遇到資料夾時卻行不通,面對一層層的資料夾,要怎樣才能簡單的快速抓取全部檔案呢?

使用 wget 就可以了! 可以參考以下的指令:
wget -r ftp://user:pass@server//absolute/path/to/directory
user 要換成你的帳號,pass 則是密碼
如果是匿名登入不需要帳密,將 user:pass@ 省略,只留下路徑即可

wget -r -nH --cut-dirs=5 -nc ftp://user:pass@server//absolute/path/to/directory
多出來幾個選項,而且server後面多一條斜線(\),可以讓 wget 的行為更合理

Install climate data operators (cdo) on Ubuntu with netCDF4 and hdf5 support

Nikolay Koldunov
CDOs can be installed from Ubuntu repositories, but they are compiled without netCDF4 and HDF5 support. As a result you can get:

Unsupported file type (library support not compiled in)

error. To solve this we have to compile cdo by ourselves.

Uninstal cdo if you have them installed from Ubuntu repositories:sudo apt-get purge cdo

Install netcdf andf HDF5 libraries:sudo apt-get install libnetcdf-dev libhdf5-dev

Download latest stable version of cdo from here

Unpack it

cd to unpacked directory

If you want to install cdo in to your system directory:./configure --enable-netcdf4 --enable-zlib --with-netcdf=/usr/ --with-hdf5=/usr/ make sudo make install

If you don't have administrative rights, of would like to have installation of cdo in other folder for any other reason, you can provide prefix:./configure --enable-netcdf4 --enable-zlib --prefix=/dir/where/to/put/cdo --with-netcdf=/usr/ --with-hdf5=/usr/ make make install

In the last case you should also add this path to your $PATH in .bashrc file:export PATH=/dir/where/to/put/cdo/bin:$PATH

note bin at the end!

Hope it will work for you :)
