If that's all you want to do then here's the pertinent sed command to do it:
sed -e 's,www.old_domain_name/user/my_username,my_new_domain_name,'
Syntax is a bit simpler when you don't use slashes as the sed substitute delimiters. You can use anything. Here I used commas.
Actually, it's not fixed. I got excited too quickly after the first file I clicked looked correct--the first file in the subdirectory.
I see no indication in terminal that the process is going or ending--no sense of when I can close terminal and move on.
Checking the directory in finder shows no updates to 'date modified' for any of the files.
So how do I know if it is in progress, or done working, aside from opening random files to see if they're 'done'?
Put it in a text file and trace it (and I don't recommend using textedit, use a real text editor like TextWrangler or BBEdit).
Say you create a text file called my-script. In terminal
chmod +x my_script
Now it's an executable script. You can type my_script from the terminal and execute it.
Of course that's the basic scheme. I leave it to you to get the pathnames corrrect.
All this is leading to the fact that if you place a
at the beginning of the script you will see each command as it is executed. I would do this on a small subset of the data until you fix the problems.
Alternatively it's only about 8 command lines so just type them on the terminal to see what happens that way.
I only gave you the central sed to edit the strings you presented in your original post. I didn't check your script and assumed you could figure out the appropriate placement.
I may have left out a few steps but maybe what I hav below is what you need:
while read f; do
sed -e 's,www.old_domain_name/user/my_username,my_new_domain_name,' < "$1/$f" >"$2/$f"
done< <(ls "$1")
This is a script as I described previously. It takes two arguments. The first is the path to the input directory and the second is the path to the output directory. So if my-script was the name of this script you would execute something like:
my-script WEB new-web
Hope this helps.
(and again it is up to you to specify the pathnames to the script and the input/output directory pathnames correctly)
Note the cryptic while loop is done to allow for the possibility that the filenames in the source directory having special characters (like blanks in them).
