Using piped input to gzip
Can anyone tell me why does'nt the following command work?

Code:
find /gfp1/home/arijit -name "*.sas7bdat" | gzip


I am trying to compress all files with extension sas7bdat with gzip.

It gives error message

Code:
gzip: compressed data not written to a terminal. Use -f to force compression.
For help, type: gzip -h

When piping to gzip it will compress the data stream it receives, not read a list of file names to compress. As such, it won't write the compressed stream to a TTY, you'll have to redirect either to another program or a file.

To do what you want, use this:
Code:
find /gfp1/home/arijit -name "*.sas7bdat" -exec gzip {} \;

Here is correct approch
Code:
find /home/test/  -type f -name "file*"  -exec gzip {} \;

OR in your case
Code:
find /gfp1/home/arijit -name "*.sas7bdat"  -exec gzip {} \;

find /gfp1/home/arijit -name "*.sas7bdat" | xargs gzip

Depending on your OS you can also check whether your gzip version support the -@ option
