# plink doesn't generate a sexcheck-file

I was executing the following command plink.exe --file GWAS --check-sex --noweb Expecthing to get a plink.sexcheck file but I don't get anything. Not even an error. The output is always:

Skipping web check... [ --noweb ]
Writing this text to log file [ plink.log ]
Analysis started: Sat Mar 13 12:24:18 2021

Options in effect:
--file GWAS
--check-sex
--noweb

75 (of 75) markers to be included from [ GWAS.map ]


Do you know what could be the issue there? I have a GWAS.map and GWAS.ped file. Do I need any additional information for this to work?
