NAME
fetch-reqs.pl
VERSION
version 0.3.1
DESCRIPTION
fetch-reqs.pl is the command-line interface for Sys::OsPackage. It installs prerequisite modules for a named Perl script, or directly installs Perl modules via the OS packaging system. It falls back to installation with CPAN if the module is not packaged for the OS.
USAGE
fetch-reqs.pl [--debug] [--quiet] [--notest] [--sudo] filename|module [...]
cat req-list.txt | fetch-reqs.pl [--debug] [--quiet] [--notest] [--sudo]OPTIONS
The following command-line flags are available.
- --notest
-
Similar to the option in cpanm, --notest installs modules without running automated tests.
- --sudo
-
Similar to the option in cpanm, the --sudo flag enables running commands with "sudo" to run install commands as the root user. The sudo command must be separately installed on the system or container if this is used.
- --quiet
-
When this flag is on, output status is reduced.
- --debug
-
This flag is used for development to print internal details of the program run. If requesting help or submitting a bug report, it is useful to include this output for developers to see what happened on your system.
The files listed on the command line should either be file names of Perl scripts or modules to scan for dependencies, or names of Perl modules to load. Each file's Perl module dependencies or each named Perl module will be installed by Sys::OsPackage using operating system packages if available, or otherwise via CPAN.
If no file or module names are inclued on the command line, then the standard input is read for those parameters, each on their own separate line.
OS PACKAGING DRIVERS
Sys::OsPackage currently contains OS packaging drivers for Fedora/RHEL/CentOS, Debian/Ubuntu, SuSE/OpenSuSE, Arch and Alpine Linux and their derivatives. More drivers can be added by creating new subclasses of Sys::OsPackage::Driver.
EXIT STATUS
Standard Unix program exit codes are used: 0 if no error, 1 if error.
SEE ALSO
Sys::OsRelease is used by Sys::OsPackage to detect the operating system by its ID. For Linux distributions, it also uses ID_LIKE data to detect common distirbutions it is derived from. For example, Linux distributions derived from Debian or Red Hat are not all known, but are recognizable with ID_LIKE.
