I have compressed files compressed using different techniques (especially unix compress). So I want to have a module that reads any of these (.Z,.bz,.tgz files) files and manipulates the data.
The data has a syntax.It contains
HEADER (some information)
BODY (some information)
FOOTER (some information)
If it were a normal text file I can get the values corresponding to HEADER BODY and FOOTER by open function.
But here the files are in different format .Z , .bz ,.tgz,.gz .But I know these are the only formats.Also I cannot rely upon the extensions of the file (a .Z file can have no extension at all).Is there a way to identify which file am I reading and then read it?If so how to read it?
Thanks and Regards,
