我有一个包含60多个netCDF（* .nc）文件的文件夹。我需要找到所有60多个数据文件的平均值，但是我的终端出现错误。
因此，我只需要知道平均60多个文件的平均值并将结果保存在output.nc文件中（我知道如何一次处理2或3个文件，但是有没有60种以上的方法？）
这是我尝试的方法：'ncra data_ncfiles/* dataaverage.nc-> *应该告诉Linux该文件夹中的所有60个文件平均。
我得到的错误是：ncra: ERROR nco_sng_sntz() reports character '' from unsanitized user-input string "CbPM_ncfiles/" is not on whitelist of acceptable characters. For security purposes NCO restricts the set of characters appearing in user input, including filenames, to: "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890_-.@ :%/". NB: This restriction was first imposed in NCO 4.7.3 (February, 2018), and may cause breakage of older workflows. Please contact NCO if you have a real-world use-case that shows why the character '*' should be white-listed. HINT: Re-try command after replacing transgressing characters with innocuous characters.
我也尝试了没有星号的方法，但没有用
更新：我再次尝试：
ncra data_ncfiles/* dataaverage.nc
并收到此错误：
ncra: ERROR no variables fit criteria for processing ncra: HINT Extraction list must contain at least one record variable that is not NC_CHAR or NC_STRING. A record variable is a variable defined with a record dimension. Often the record dimension, aka unlimited dimension, refers to time. To change an existing dimension from a fixed to a record dimensions see http://nco.sf.net/nco.html#mk_rec_dmn or to add a new record dimension to all variables see http://nco.sf.net/nco.html#ncecat_rnm
答案 0 :(得分：1)
此命令
ncra data_ncfiles/* dataaverage.nc
依靠shell globbing来扩展文件名列表。如果ls data_ncfiles/*提供相同目录中的预期文件列表，它将起作用。您的帖子尚不清楚，但是您可能已通过使用引号关闭了glob。
下一个错误ERROR no variables fit criteria for processing通常在您的输入缺少记录维时发生。令人敬畏的错误恰好指向有关如何解决此问题的说明。请遵循那些说明。
