How to resolve this?

you obviously have to figure out, what format the file you downloaded is in. for example, whether it is plain tar without compression, or has a different non-gzip compression or was corrupted and thus is in no discernible file format. keep in mind, that typically a file name must not be correlated with the file format that its data is stored in. a good way to heuristically determine (known) file formats is the ‘file’ command.

at any rate, this is impossible to debug and thus give any specific advice on from remote.

Respected Sir,

Following is the result of 'file ’ command.

[anilman@…8128… lammps_22aug2018]$ file
Usage: file [-bchikLlNnprsvz0] [–apple] [–mime-encoding] [–mime-type]
[-e testname] [-F separator] [-f namefile] [-m magicfiles] file …
file -C [-m magicfiles]
file [–help]

Whether it give any clue about the file format or anything that can resolve the issue?
