For compressing, just add the z option.
For excluding directories, add their names to the exclude file.
for the compressing, is it similiar with
Code:
tar -cvf - /jfma/test1 | compress -c > test.tar.Z

Some will accept the -z flag as part of the tar command, some will not and you have to pass the output to a compression program afterwards, but the default compression programs can vary depending on your OS too, e.g. compress, gzip, bzip, etc.

If none of the above posts have given you an answer, please post your OS and version and we can find the appropriate process for you.

NAME
comprez - safely (un)tar and (de)feather files and directories SYNOPSIS
comprez [ -t | -T ] [ -v | -V ] [ -l | -L ] [ -gz | -z | -I | -lz | -Z | -zip | -jar ] [ -# ] [ -s suffix ] [ -m mode ] [ -p | -P ] [ -h ] [ -- ] file ... DESCRIPTION
Comprez is a simple, safe and convenient front-end for the compress(1), uncompress(1), gzip(1), bzip2(1), lzip(1), tar(1), zip(1) and unzip(1) utilities for compressing and uncompressing files and directories. It processes each of its arguments according to the type of the file or directory given: If the argument is a plain file, then the file is compressed, ie, feathered. If the argument is a compressed file with a name ending in .Z, .gz, .z, .bz2, .lz, .zip or .jar, then the file is uncompressed, ie, defeathered. If the argument is a directory, then the directory is archived into one tar or zip file which is then compressed, ie, tarred and feathered. If the argument is a compressed tar or zip archive with a name ending in .{tar.,tar,ta,t}{Z,gz,z,bz2,lz} or .{zip,jar}, then the archive is uncompressed and untarred, ie, untarred and defeathered. The new compressed or uncompressed version will be in the same directory as the original. A compressed file is always uncompressed into a file with the same name sans the feather suffix. A compressed tar or zip archive is always unpacked into a subdirectory with the same name as the archive sans the tar and feather suffix, even if the archive did not itself contain such a subdirectory. OPTIONS
-- Interprets all following arguments as files instead of options. -# Where # is a digit from 1 through 9. This option is passed on to gzip(1), bzip2(1), lzip(1) and zip(1) when feathering with them. --fast may be used instead of -1 and --best instead of -9. -gz Uses gzip(1) and a .gz compression suffix when feathering. -h Prints a helpful usage message. -I Uses bzip2(1) and a .bz2 compression suffix when feathering. -l Lists the file or directory name created resulting from each argument. -L Does not report created files or directories. Default. -lz Uses lzip(1) and a .lz compression suffix when feathering. -m mode Apply the given chmod(1) mode argument to any created tar and feather files. Before this argument is applied, the files have the same read and write permissions as the directories from which they were created. For security, the default argument is go-rwx. If the mode is -, then no argument is applied. See chmod(1) for all other allowable formats of this argument. -p Preserves modes when untarring by giving the p flag to tar(1). Default. -P Doesn't preserve modes when untarring by not giving the p flag to tar(1). This option may be necessary on systems where ordinary users are allowed to run chown(2). -s suffix Creates tar and feather files using the given suffix style. The default suffix style is .tar.Z. Note that the suffix style does not dictate the program used for feathering nor the compression suffix. -t Only lists the table of contents of the given files. Does not make any changes. -T (Un)tars and (de)feathers the given files according to their type. Default. -v Verbose output. For example, reports compression ratios when feathering. -V Non-verbose output. Does not report compression ratios. Default. -q is a synonym. -z Uses gzip(1) and a .z compression suffix when feathering. -Z Uses compress(1) and a .Z compression suffix when feathering. Default. -zip, -jar Uses zip(1) and a .zip or .jar compression suffix when tarring and/or feathering. The zip format combines tarring and feather- ing. WARNING: zip does not preserve complete Unix filesystem information for the files it archives, such as links, some permis- sions, etc. A tar(1)-based format should be used if this is required. ENVIRONMENT VARIABLES
ZOPTS This variable may be set to a string of the above options to supersede the default settings. They may still be overridden by options given on the command line. GZIP This environment variable for gzip(1) is not passed on by comprez so that gzip's behavior is standard and predictable. ZIPOPT, UNZIP These environment variables for zip(1) and unzip(1) are not passed on by comprez so that their behavior is standard and pre- dictable. BUGS
There should be an option to allow the use of another directory for temporary files needed during the (un)tarring and (de)feathering pro- cesses. This would make comprez more useful when the quota or disk is nearly full. There should be -k and -K options for keeping the original input files or not. CAVEATS
Comprez is written to work with gzip versions 1.2.3 and 1.2.4, bzip2 versions 0.9.0 and 1.0.0, Unix zip version 2.0.1 and Unix unzip ver- sion 5.12. Other versions will probably work safely, too, but should still be checked for compatibility. Every effort has been made to assure that the use of this program will not lead to the inappropriate deletion or corruption of any files. However, there are never any guarantees, so please use at your own risk. VERSION
