Hello am24,
Not sure about your complete requirement but storing whole file's content into a single variable doesn't seems to be a good method, in spite of that you could read a file line by line by using while loop or you could use awk, sed to accomplish your requirements, if you have any queries please do let us know complete requirement with sample Input_file and expected output, hope this helps.
Thanks,
R. Singh

demos::widget_lib::trace2(3pm) perl/Tk Documentation demos::widget_lib::trace2(3pm)
NAME
Tk::TraceText - Text contents defined by a traced variable.
SYNOPSIS
$tt = $parent->TraceText(-option => value, ... );
DESCRIPTION
Create a new TraceText widget that is derived from the standard Text widget. Because it inherits all the base options and methods it
behaves just like a Text widget. Additionally, TraceText adds a -textvariable option, which is a reference to a Perl scalar that defines
the contents of the widget.
Based on the Tcl/Tk TracedText "overridden widget" by Kevin Kenny.
-textvariable
A scalar reference. The value of the variable defines the contents of the TraceText widget. Using the keyboard to insert or delete
text changes the value of the variable, and changing the variable alters the contents of the TraceText widget.
METHODS
Standard Text widget methods.
ADVERTISED SUBWIDGETS
None.
EXAMPLE
my $tt = $mw->TraceText( -textvariable => $scalar );
