lathavim / pludi, thank you for your super-fast reply!
DukeNuke2 - apologies for not giving correct subject text!

lathavim / pludi - If I was running either of your commands manually it would work perfectly as I would be able to enter the name of the file I want to modify, however, remember my filename changes each month and I want to automate this.

Using either

sed -e '2,1d' file >file.tmp&&mv file.tmp file
or
perl -ni -e 'print if !/^\s*$/;' file.txt

requires me to enter the filename - but like I said, it changes each month and I want to automate the process. I need the script to actually fill in the filename for me. The file will always start with Myfile, and it will be the only file in the directory starting like this.

I had thought of using

ls Myfile* > nameholder

This creates a file called nameholder, within which is the name of the current months file to be modified.

If I could then somehow get the script to read that file and save the value as a parameter I could then use that parameter in the sed or perl command

sed -e '2,1d' $myfile >file.tmp&&mv file.tmp $myfile

Thanks for your excellent suggestions though.

Any thoughts?

set_color

set_color(1)                                                           fish                                                           set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
