Additional parameters
For the not-so-inpatient user, the self-extractable archive supports few command line
parameters, described in the following table.
DescriptionParameter
Prints the short help messages.--help
This will print archive information, such as the title, the default target
directory, the embedded script to be run after unpacking, the
--info
compression method used, the uncompressed size, the date of
packaging.
This option will print the content of the embedded archive. The listed
files are the engines, the program binaries, the embedded
--list
documentation, the install and uninstall script along with their size and
permissions.
This is one of the most useful options, because it enables the user to
verify the package integrity, as stated above. The integrity is checked
--check
comparing theembedded md5 checksum (generatedduring packaging)
with the one computed the moment of checking. If they match, the
output will be the following:
MD5 checksums are OK. All good.
If not, an error message will be shown, displaying the unequal stored
and computed checksums, such as
Error in MD5 checksums: X is different from Y
The user will be asked to confirm every step of the install process.--confirm
By default, the archive content is extracted to a temporary directory,
which will be removed after the embedded installer exits. Passing this
parameter to the script will not remove the directory.
--keep
You can specify another directory to extract the archive to, if you don't
want to use the default name. Note that this target directory will not be
removed.
