Shell Programming and Scripting

Hi all,

I have a script that creates folders depending on what variables i enter when calling the script. This all works as expected but what i want to do is add some additional data into another file so that other scripts are aware of this file.

I've found the following sed command which works to my needs. It enters the given details into a given line

Code:

sed "36a\mv -v $foo/"$SHOW"\ $bar/$SHOW/" test2.sh > test3.sh

the problem i'm having is that when the sed command has run, $SHOW displays still in the new file as $SHOW. Is there something i'm doing wrong as to why $SHOW wont "resolve" to the text i need to to be?

also is there an easier way to output the results of SED back into the original file? Instead of having to manipulate it in such a way that i end up with the original file name?

Would you mind showing us a sample input and output? Thanks

First part is unclear what you are trying to do.

Second part solution is "sed -i" if your version of sed supports it.

This may be solved by other solution than sed.
Show your input and what you like to get out, and what algorithmic you use to get the output.

Your command works perfectly once the variables are correctly set. This does not mean it can't be improved...

So my initial script has a case command in which calls up functions according to which option i select. Within one of those functions i have the sed code which is to take the input of $SHOW and apply it into the file.

so say $SHOW = test foobar
then the sed command should should run like:

Code:

sed "36a\mv -v $foo/"test foobar"\ $bar/test foobar/" test2.sh > test3.sh

So in tesh3.sh i should see around line 36 the following:

Code:

mv -v $foo/"test foobar"\ $bar/test foobar/

but i always get $SHOW appear in the final file and it never takes the input from $SHOW and replaces it. $foo and $ bar are part of the test3.sh script so all they need to do is be entered into the test3.sh file.

Other parts of the function works when $SHOW is called its just sed that doesn't like the input.

Hope that helps.

It would help to show a complete test script.

Also, use code tags.
