sczip

Compress or expand files with ZIP algorithm

Description

sczip can compress and decompress data using the ZIP algorithm (PKZIP). It is not meant to supersede any available packagers but a little helper to decompress SC3 zipped XML formats. Like GZip, sczip can only handle one file and does not support archives. It compresses a byte stream and outputs a byte stream.

Examples

Decompress a file

sczip -d file.xml.zip -o file.xml

sczip -d file.xml.zip -o file.xml

Compress a file

sczip file.xml -o file.xml.zip

sczip < file.xml > file.xml.zip

Generic

-h, --help

show help message.

-V, --version

show version information

--config-file arg

Use alternative configuration file. When this option is used the loading of all stages is disabled. Only the given configuration file is parsed and used. To use another name for the configuration create a symbolic link of the application or copy it, eg scautopick -> scautopick2.

--plugins arg

Load given plugins.

-D, --daemon

Run as daemon. This means the application will fork itself and doesn’t need to be started with &.

--auto-shutdown arg

Enable/disable self-shutdown because a master module shutdown. This only works when messaging is enabled and the master module sends a shutdown message (enabled with –start-stop-msg for the master module).

--shutdown-master-module arg

Sets the name of the master-module used for auto-shutdown. This is the application name of the module actually started. If symlinks are used then it is the name of the symlinked application.

--shutdown-master-username arg

Sets the name of the master-username of the messaging used for auto-shutdown. If “shutdown-master-module” is given as well this parameter is ignored.

Verbosity

--verbosity arg

Verbosity level [0..4]. 0:quiet, 1:error, 2:warning, 3:info, 4:debug

-v, --v

Increase verbosity level (may be repeated, eg. -vv)

-q, --quiet

Quiet mode: no logging output

--component arg

Limits the logging to a certain component. This option can be given more than once.

-s, --syslog

Use syslog logging back end. The output usually goes to /var/lib/messages.

-l, --lockfile arg

Path to lock file.

--console arg

Send log output to stdout.

--debug

Debug mode: –verbosity=4 –console=1

--log-file arg

Use alternative log file.

Mode

-d, --decompress

Decompress.

-o, --output file
