gzip problem

[Hunki]

I have a script in which gzip is being called and trying to overwrite a file and I am being prompted in the following way:

0501.gz already exists; do you wish to overwrite (y or n)?

Is there a way I can circumvent this so that I don’t get the prompt, I tried passing >/dev/null to the gzip command but that hangs until u press enter.

Add -f to the gzip command:

-f --force
Force compression or decompression even if the file has multiple
links or the corresponding file already exists, or if the
compressed data is read from or written to a terminal. If the
input data is not in a format recognized by gzip, and if the
option --stdout is also given, copy the input data without change
to the standard ouput: let zcat behave as cat. If -f is not
given, and when not running in the background, gzip prompts to
verify whether an existing file should be overwritten.

Hi Hunki,

$ gzip -f ...

A "man gzip" would have revealed the -f option.
