    Hi all.
    Was after some more help and advice. My little project just keeps on growing and I always get side tracked when I wish to learn summet new.

    What I would like to know is,,,,,

    Is it possible to add lines to an existing .txt file...

    Exaample if i had this text doc

    (my "makelist.cmd" gave me this .txt.....hark at me...)

    i want to add for example "= 1980,,,,,,,1980,0,0" to each line and end up with the following .txt

    I have been doing it one line at a time and some of my .txt have quite a few lines in them so being able to run a .cmd and have the lines added and a new .txt file made would be great.

    tried to find how to do this on the net but all I see is gobbeldy gook and I dont understand it....

    So any help,tips and pointer will be fantatstic....

    I would use powershell, heres an example that will replace = with = 1980,,,,,,,1980,0,0 in a file named test.txt:

    Code:
    type test.txt | powershell -Command "$input | ForEach-Object { $_ -replace \"=\", \"= 1980,,,,,,,1980,0,0\" } > test.txt"
    ;)

    Hi Aphawaves...

    This works fine and wow,it's prety cool. butttttttttttt

    One ikkle problem....The lines on my text file do not end with "=" They are just the file name and ext "viahub3.cat"

    If I manually add a "=" to each line your code works a treat.

    Been looking at it and it uses "-replace". i have been looking at powershell commands and there is an "add-content"

    I have no idea if this will work,I have tried just replacing repalce with add-content but no luck.
    I simply removed the "=" from your code and the gates of hell open up in the test.txt.
    i tried "" and all the lines dissapear,like magic.....

    I will read up more on the power shell commands....never even heard of them till just now...

    cheers..

    Ok try this to append each end of line:

    Code:
    type test.txt | powershell -Command "$input | ForEach-Object {$_ -replace \"$\", \" = 1980,,,,,,,1980,0,0\"} | out-file test.txt"
    ;)
