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 {} \;

gzip produces different output from the same input

Hi there, I'm puzzled. Compressing the same file (same name, same md5sum) at two different times will produce a different output. I mean the md5sum of the resulting .gz files are different. Does it make any sens to any of you? I'd like some explanations if you know what's going on. Thanks... (4 Replies)

NAME
znew - recompress .Z files to .gz files SYNOPSIS
znew [ -ftv9PK] [ name.Z ... ] DESCRIPTION
Znew recompresses files from .Z (compress) format to .gz (gzip) format. If you want to recompress a file already in gzip format, rename the file to force a .Z extension then apply znew. OPTIONS
-f Force recompression from .Z to .gz format even if a .gz file already exists. -t Tests the new files before deleting originals. -v Verbose. Display the name and percentage reduction for each file compressed. -9 Use the slowest compression method (optimal compression). -P Use pipes for the conversion to reduce disk space usage. -K Keep a .Z file when it is smaller than the .gz file; implies -t. SEE ALSO
gzip(1), zmore(1), zdiff(1), zgrep(1), zforce(1), gzexe(1), compress(1) BUGS
Znew does not maintain the time stamp with the -P option if cpmod(1) is not available and touch(1) does not support the -r option. ZNEW(1)
