I am facing issue with gzip.

As far my knowledge gzip coomand zip the file and replaces xxx.gzip over original file.

But here it zip the file and keeps both files original and zipped file. so wastage of disk space.

My server is B.11.23

Pleas suggest on this..

Hi

What is your command? And don't use the -c option. Just 'gzip file'.

"man gzip" might extend your knowledge.

Where is "here"?

A fair question.

in fact while gziping, it creates a new file and remove the original one if it is a success

gzip toto
will first open a toto.gz then compress outputing to toto.gz, and if there is no error
remove toto

so at a time toto and toto.gz size must be available

if you don't have enough available space locally, you can do the following

gzip /somewherewithspace/gzipfile.gz

Hi Admins,

Thanx for your responses and sorry for my delayed response.

Actually issue is not with OS side.Everyday syncing and splitting is happening between PROD and Backup servers.During this time file will be overwritten in backup server from prod server.But some files are not overwritten,only appeneded.

Perhaps you should start by explaining
exactly what you're doing, and then exactly
what you see happening.

Please check ypu permisions, it sounts like the user that is zipping the file has enauf permisions to remove the file.
does a normal rm works (not -f) of the file you have zipped (from same server, user) as the zip command is running.

besides the mounting/privilages cause I do not know if there can be someting els.

Hi,
I am not sure if there is an option for deleting the original file after compressing it ,but you can create a script that compress the file ,then deletes the original file ,like:
gunzip
rm

Hello Himacs,

yes you are correct gzip compress the file and then remove the original one, but while compressing the file it will consume the double size on the device, when it compress successfully then it will remove the original file and only xxx.gzip file remain.

you can check:-

just create a temporary file and gzip them after zipped the file try to call that one it will never list with the original file.

Please correct me if I am wrong. :)

Rahul Rai.

Hopefully not double. :-)
You can check this by using tusc.
