compressing files

[Waqar Razi]

How can we compress files?

[Pete Randall]

Have a look at the man page for compress.

Hi Wagar, you can you gzip or compress commands. The most used is gzip.

For further information use man gzip.

This is the command used by me:

#gzip -9 filename

with -9 you have the best compress but the slowest compression method. The default compression level is -6.

Best regards.

As mentioned by Pete, there is compress(1) and uncompress(1). And by Ernesto, there is gzip and gunzip, in /usr/contrib/bin/. This is much better than simple compress.
You could also download zip/unzip.

I use file compression programs, like gzip,
bzip2, and Zip.

Which files? Why?

Individual files, or whole directory trees,
or what?

The best way to do what you want may depend
on exactly what you would like to do, and my
psychic powers are too weak to tell me that.

bzip2 often compresses better (and more
slowly) than gzip. Zip may be more
convenient if you're sending the files to a
non-UNIX system.

HI,
If you don't have access to an zipping utility, (or if you want install it) you can use the jar command, included in included "bin" directory of the Java, as long as it is reachable from your executable path.
jar -? for the option

HTH,
