Hello. I have an external program called Lin.exe. This program accept (read) one file and write to another file. In windows cmd this can be done as follows:

Lin.exe /f command_file.txt /o output_file.txt

In matlab windows, I can do this as:

 yourCommand2 = strcat('"C:\Program Files (x86)\Lin.exe"',' /f',' "','command_file.txt, '"', ' /o', ' "','output_file.txt', '"');
 system(yourCommand2);

There is a Linux version of this exe file that is ./Lin.exe. The file located in "/global/storage/./Lin.exe". I want to use use matlab in linux to be able to run this program using "unix" command. However, this only can run Lin.exe and does not read any file or write to any file given.

yourCommand=['"/global/storage/./Lin.exe"'  ' /f ' '"/home/merakpeep.rwd"'  ' /o '  '"test.txt"' ]
unix( yourCommand);

Can you please help on this?

在 MATLAB Online 中打开

Please try

! /global/storage/Lin.exe --?

and see if it gives output.

I would tend to suspect that a Linux version would use Linux option notation such as

   cmd = '/global/storage/Lin.exe' 
  infile = '/home/merakpeep.rwd'
  outfile = fullfile(pwd, 'test.txt')
  YourCommand = sprintf('"%s" -f "%s" -o "%s"', cmd, infile, outfile) 
  unix(YourCommand)

Or perhaps with

YourCommand = sprintf('"%s" < "%s" > "%s"', cmd, infile, outfile)
