Question Changing Special Characters Using Sed
Hi. Does anyone know how to use the sed command to change the special border characters on this .per file. I have to edit about 80 .per files. I need a sed script to change the below 3 and A characters.

You have more funky characters in that file than the two that you mentioned. You may want to change them as well.

I will show you how I would approach something like this. I am using ksh as my interactive shell. That is important because my solution depends on the echo statement.

Let's say that I want to change all of my Ä characters to be a hyphen character. It is possible that a simple "sed s/Ä/-/g" would work, But I don't like to use non-ascii characters.

First I need to know the octal value for Ä and I will use od -c for that.
od -c < funky.txt
OK, it is 304.

Now I need an echo statement to create a single instance of that character. I will test the echo statement to be sure it's working:
echo \\0304\\c ; sleep 5
The sleep 5 gives me some time to view the character before my prompt overwrites it.

Now I can construct the sed statement:
sed "s/$(echo \\0304\\c)/-/g" < funky.txt

Perderado,

Can I use the same procedure for the Bash shell?

It looks like
echo -e \\304\\c
will work in bash.

Perderabo,

Thanks. The echo command returned the character.
