[Solved] How to refer to input file in code?
This may be a dumb question, but googling is not giving me an answer. I'm trying to figure out how to refer to an input file in my code.
Lets say i run a script in bash:
"sh shellscript.sh inputfile"
(Inputfile will be variable...whatever file i run the script on)
I wanted to make variables like "DIR=dirname inputfile" and "BASE = basename inputfile" so that I can use those to make subsequent files based off of the basename and put them in directories based on the dirname rather than having to cd to the directory to run the script and keep the output files in that folder. The problem is that I don't know how to refer to the inputfile to initially set these variables.
Also, if I set these variables at the beginning of the whole shell script, they will stay throughout for all of the other commands I am performing, right?

prophet::cli::command
Prophet::CLI::Command(3pm) User Contributed Perl Documentation Prophet::CLI::Command(3pm)
Registering argument translations
This is the Prophet CLI's way of supporting short forms for arguments, e.g. you want to let '-v' be able to used for the same purpose as
'--verbose' without dirtying your code checking both or manually setting them if they exist. We want it to be as easy as possible to have
short commands.
To use, have your command subclass do:
sub ARG_TRANSLATIONS { shift->SUPER::ARG_TRANSLATIONS(), f => 'file' };
You can register as many translations at a time as you want. The arguments will be translated when the command object is instantiated. If
an arg already exists in the arg translation table, it is overwritten with the new value.
require_uuid
Checks to make sure the uuid attribute is set. Prints an error and dies with the command's usage string if it is not set.
edit_text [text] -> text
Filters the given text through the user's $EDITOR using Proc::InvokeEditor.
edit_hash hash => hashref, ordering => arrayref
Filters the hash through the user's $EDITOR using Proc::InvokeEditor.
No validation is done on the input or output.
If the optional ordering argument is specified, hash keys will be presented in that order (with unspecified elements following) for edit.
If the record class for the current type defines a "immutable_props" routine, those props will not be presented for editing.
False values are not returned unless a prop is removed from the output.
edit_props arg => str, defaults => hashref, ordering => arrayref
Returns a hashref of the command's props mixed in with any default props. If the "arg" argument is specified, (default "edit", use "undef"
if you only want default arguments), then "edit_hash" is invoked on the property list.
If the "ordering" argument is specified, properties will be presented in that order (with unspecified props following) if filtered through
"edit_hash".
prompt_choices question
Asks user the question and returns 0 if answer was the second choice, 1 otherwise. (First choice is the default.)
prompt_Yn question
Asks user the question and returns true if answer was positive or false otherwise. Default answer is 'Yes' (returns true).
print_usage
Print the command's usage message to STDERR and die. Commands should implement "usage_msg", which returns the usage message.
If the usage message method needs arguments passed in, use a closure.
get_cmd_and_subcmd_names [no_type => 1]
Gets the name of the script that was run and the primary commands that were specified on the command-line. If a true boolean is passed in
as "no_type", won't add '<record-type>' to the subcmd if no type was passed in via the primary commands.
