how to decompress gzip file with extension .cif?
 

i have a file which is gzip compressed and the extension is .cif.
when trying to decompress it using the command " gunzip -df abc.cif " it says
unknown suffix ignored. can u suggest a solution for this?

first execute the file utility ( 'file abc.cif' ) to make sure that it is a gzip file ... if it is then simply rename the file ( 'mv abc.cif abc.zip' (or is it .gz) ) and then unzip as usual.
