Perl Help - Assigning variables to text file contents
I am looking to create a perl script which will take numbers from a simple text file, convert them from decimal to hex, and then rewrite those values in the file or create a new file with the hex numbers(whichever's easier).

My text document for example would be something as simple as

1312
4646
4231
3566
1341
2331

I know how to use sprintf, but I don't know how to make the function convert an entire file. I can only get it to convert one number that I input by myself. Does anyone know how to do this? Any help would be appreciated

	 colortest-python

DESCRIPTION

       Displays 256, 88 and 16 color tables depending on what the terminal supports. Also provides for conversion between 256 and 88 color values.

       The program automatically detects 8, 16, 88, 256 color capabilities (via ncurses) and displays the appropriate color charts. Program can
       display the colors as blocks or 2d cubes optionally with color values overlaid in int or hex values, it can show the full rgb text string
       and show the display with a vertical (default) or horizontal orientation.

       In addition to the color charts it can also convert between 256 and 88 color values. This can be useful when converting various terminals
       like between urxvt and xterm-256.
