Getting RECFM and LRECL of a file on Unix

[Magdalena318]

Dear community,

How could I get the values of RECFM and LRECL of an arbitrary file on Unix. 

I know that on Windows I could simply use foptname function but on Unix these options are not available.

Thank you in advance!

What are you trying to achieve with the file?

The options used depend very much on what you need to do with it..

UNIX (like Windows) does not have the concept of file organization, this is strictly a feature of older mainframe systems like z/OS (MVS, previously OS/360). To UNIX and Windows, a file is simply a stream of bytes.

Therefore the FINFO function cannot give you this information, as it does not exist.

For the purpose of reading a specially formatted file, the programmer needs to supply these parameters, and for this he/she needs the documentation of the fiie.
