UNIX for Dummies Questions & Answers

hi
i would be grateful for some help on the following q.

"Write a script that takes two arguments. The first being a line of text, the second being your newly created file. The script should take the first argument and insert it into the very top ( the first line) of the file named in your second argument.

Note! The file must retain the original name

thanks a million

i have a feeling its involving sed

Give this a try:

Code:

#!/usr/bin/sh

touch $2
echo $1 > $2

Then :

Code:

# ./your_script HELLO myfile

I need to add text on top of an original file, this method deleted my file and just left HELLO on top..

Any suggestions

Sounds like you tested this on an important file...don't do that.

">" will overwrite your file, ">>" will add to your file.

that worked fine to append to end of line, how do you append on top of file, or in the middle say 5 lines down. Thanks for the quick response

Now you are asking questions beyond parameters and simple redirection. This kind of question comes up alot, try searching the forums for examples using "sed". Once you have searched a few times, you'll find your own answers very quickly. If you get really stuck, post your question again, there is alot of help here.

thanks tmarikle
