Decompressing gz SQL file

Question

So I want to decompress my something.gz file. Whenever I try to do this by using gunzip it ends after a little while saying there was an unexpected end of the file. The file itself is about 4gb.

Would appreciate any help regarding this problem.

Command: gunzip < db-20180518060048.sql.gz > db-20180518060048.sql

Response: gzip: stdin: unexpected end of file

Ends at: ('250

Answer 1

You have to use -d to decompress:

Your command would be:

gunzip -d db-20180518060048.sql.gz

Edit due to comment:

To test validity of your archive you can run

gunzip -t db-20180518060048.sql.gz

-t --test test compressed file integrity

The correct is only no output. Any other means that your archive is damaged.
