=head1 COMPLETION

This script has shell tab completion capability with support for several
shells.

=head2 bash

To activate bash completion for this script, put:

 complete -C create-random-file create-random-file

in your bash startup (e.g. F<~/.bashrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is recommended, however, that you install modules using L<cpanm-shcompgen>
which can activate shell completion for scripts immediately.

=head2 tcsh

To activate tcsh completion for this script, put:

 complete create-random-file 'p/*/`create-random-file`/'

in your tcsh startup (e.g. F<~/.tcshrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is also recommended to install L<shcompgen> (see above).

=head2 other shells

For fish and zsh, install L<shcompgen> as described above.

=head1 CONFIGURATION FILE

This script can read configuration files. Configuration files are in the format of L<IOD>, which is basically INI with some extra features.

By default, these names are searched for configuration filenames (can be changed using C<--config-path>): F</home/u1/.config/create-random-file.conf>, F</home/u1/create-random-file.conf>, or F</etc/create-random-file.conf>.

All found files will be read and merged.

To disable searching for configuration files, pass C<--no-config>.

You can put multiple profiles in a single file by using section names like C<[profile=SOMENAME]> or C<[SOMESECTION profile=SOMENAME]>. Those sections will only be read if you specify the matching C<--config-profile SOMENAME>.

You can also put configuration for multiple programs inside a single file, and use filter C<program=NAME> in section names, e.g. C<[program=NAME ...]> or C<[SOMESECTION program=NAME]>. The section will then only be used when the reading program match...

You can also filter a section by environment variable using the filter C<env=CONDITION> in section names. For example if you only want a section to be read if a certain environment variable is true: C<[env=SOMEVAR ...]> or C<[SOMESECTION env=SOMEVAR ...

To load and configure plugins, you can use either the C<-plugins> parameter (e.g. C<< -plugins=DumpArgs >> or C<< -plugins=DumpArgs@before_validate_args >>), or use the C<[plugin=NAME ...]> sections, for example:

 [plugin=DumpArgs]
 -event=before_validate_args
 -prio=99
 
 [plugin=Foo]
 -event=after_validate_args
 arg1=val1
 arg2=val2

 

which is equivalent to setting C<< -plugins=-DumpArgs@before_validate_args@99,-Foo@after_validate_args,arg1,val1,arg2,val2 >>.

List of available configuration parameters:

 format (see --format)
 interactive (see --interactive)
 naked_res (see --naked-res)
 name (see --name)
 overwrite (see --overwrite)
 patterns (see --pattern)
 random_bytes (see --random-bytes)
 size (see --size)

=head1 ENVIRONMENT

=head2 CREATE_RANDOM_FILE_OPT

String. Specify additional command-line options.

=head1 FILES

=head2 /home/u1/.config/create-random-file.conf

=head2 /home/u1/create-random-file.conf

=head2 /etc/create-random-file.conf

=head1 EXAMPLES

=head2 Create a file of size 1MB containing random bytes

 % create-random-file file1 1M

=head2 Like the previous example (--random-bytes is optional)

 % create-random-file file2 2M --random-bytes

=head2 Create a file of size 3.5KB containing repeated pattern

 % create-random-file file3 3.5K --pattern AABBCC

=head2 Create a file of size 4KB containing random sequences of A, B, C

 % create-random-file file4 4K --pattern A --pattern B --pattern C
