How to use a Shell Script for specific commands

I have a set of commands that I am using to copy specific areas of source code in a Cold Fusion document and export the code into recreations of the original files into a sub-directory. Here are the 3 commands I am using:

mkdir ./out && for x in *.cfm; do awk '{FS="<!-- InstanceBeginEditable name=\ "title\" -->";
  RS="<!-- InstanceEndEditable -->"; print "<!-- InstanceBeginEdit able name=\"title\" -->" $2  "<!-- InstanceEndEditable -->"}' $x > ./out/$x; done

for x in *.cfm; do awk '{FS="<!-- InstanceBeginEditable name=\"content\" -->" ; RS="<!-- InstanceEndEditable -->";
 print "<!-- InstanceBeginEditable name=\"c ontent\" -->" $2  "<!-- InstanceEndEditable -->"}' $x >> ./out/$x; done

for x in *.cfm; do sed -i -e 's/<!-- InstanceBeginEditable name="title" -->ht ml<!-- InstanceEndEditable -->//'
 -e 's/<!-- InstanceBeginEditable name="title"  --><!-- InstanceEndEditable -->//' -e 's/<!-- InstanceBeginEditable name="cont ent" --><!-- InstanceEndEditable -->//'
 -e 's/<!-- InstanceBeginEditable name=" content" -->html<!-- InstanceEndEditable -->//' ./out/$x; done

The first command is making the sub-directory. It is also printing the area of code I want that is in between the two comment tags and exporting it into the same file name that the extraction was done, only into that sub-directory.

The second command is doing the exact same thing as the first command (minus the make directory command), except this one is aimed for a second comment phrase.

The third command is to delete unnecessary comment strings that would appear after using the first two commands.

I am very illiterate when it comes to this type of stuff. How I have gotten this far is by help of a co-worker. I understand the commands listed above, but that is basically all I know (exceptions are basic commands like pwd, ls, echo, etc.). I am using Cygwin on Windows XP Pro.

Now to the point of things. I want to be able to put these commands in a shell script so I do not have to keep typing them in every for every single web directory that I will use these commands on. Is there any simple way to do this? And can I use Notepad++ to create/edit the shell script?

Just for you, I've downloaded and installed Cygwin!

I've been using it for about three minutes, and it's driving me up the wall already!

Copy your code into an editor (preferably not notepad!) and save it somewhere. If you use the script often, then /usr/bin, why not?

(let's assume notepad!)
cd /usr/bin
notepad cfCopy

Paste your code, save and exit.

Now, Notepad, being clever, will call your file cfCopy.txt, so...

mv cfCopy.txt cfCopy

Now you can "cd" to anywhere and run cfCopy.

If you chose to put the script somewhere else, not in your path (like /usr/bin), edit your bash profile:

vi .bash_profile

and at the end, add the line:

"vi .bash_profile" doesn't work, as it seems cygwin doesn't come with vi (maybe it does, but I didn't have a good look yet). I would download WinVi and put it in /usr/bin! Like I just did. Then you'll never have to use notepad again.

Hope this helps!

scottn, thank you for the reply!

I did as you said, but when I tried to run it I got the following error:

/usr/bin/cfm: line 4: syntax error: unexpected end of file

What do I seem to be doing wrong?

I also renamed the command file to and Im getting the exact same error.

I had the exact same problem at first.

After installing cygwin I wrote a "hello world" equivalent script to test it:


Which gave this error.

Then I fiddled with it adding blank lines at the end, etc.

But I eventually got it working (I've had colds that came and went quicker) by using WinVi (again with some fiddling).

I can't believe I'm the first person to write a script in Cygwin (I most certainly am not).

But I can say that what I wrote does work! I got it to work by "fiddling".....

Can anyone here from the Cygwin community - if there is such a thing - recommend something, anything, that means we can write a basic script without having to muck around for ages pampering to every of Windows' short-comings in relation to saving a basic text file to disk?!

I am using Cygwin because my co-worker said to use it. Is there any other Unix command line interfaces for Windows that might work better than Cygwin?

From the scripting perspective, there's not a problem. For me the problem is from the Windows (DOS) side. We must be doing something wrong.

Just "fiddle" until a Cygwin guru turns up...

I've just played around some more, and it seems that (in notepad) adding a blank line at the very end makes it work.

I will have to Wikipedia the origins of CRLF. For the life of me I can't see why both are neccessary. UNIX didn't have both for 40 years, and noone died!

I have done that as well and I get the same exact error. Not sure what I am doing wrong.
