Top Forums Shell Programming and Scripting Shell Script to replace tokens in multiple files Post 302250517 by cbo0485 on Thursday 23rd of October 2008 02:34:45 PM

Okay, I have about, 8 variables(now that I think about it, variable isn't the best name for them. More just tags that I have created in the following format to make it easy to replace them manually, which I am now trying to do with a script). All named in this format


@tag1@
@tag2@
@tag3@
etc
.
.
.
Now the text inside the @..@ tag doesn't follow the naming convention of tag1.2.3.4.... etc, but it was just easier to use that on here.


The file names that hold these tags are as follows:

startTestABC
stopTestABC
deleteABC
rotateABC

A little more information would be that those ABC scripts all set some variable equal to the tag, ie

TEST_NAME="@tag3@"
ANOT_VAR="@tag4@"

That way, when I run the script I can replace all the @...@ tags with what I need, and then the bottom of the script calls everything by the constant variable names.

I was thinking either the script has a header that I could vi it and change it b/c this script will be used over and over with different values for the tags each time. So, either a header section, or even an interactive script where it asks for the values, stores them, then uses those to run the replace command in each script.

Output is obviously the updated ABC script. It doesn't even need to create the new files, all it has to do is modify the existing script, b/c I have my directory which holds these scripts, and then when I use them I always have to move them somewhere else, and then run the replace script from the new directory.
