Shell Programming and Scripting

Hi guys

I having som problem trying to use sed to get a file and insert inside another one. I'll try to explain better.

I have a base.txt and using sed(having a array variables) I'm chaging some strings inside this file and saving as base1.txt. until here okay.
Then, I have to get this base1.txt and insert it inside another file called script.txt.
Well, If I didn't have any looping so far so good. Then, when the script restart, it has to change the base file again, with a different variable(until here okay), and then get this base1.txt again and insert at the same old file script.txt.

The problem is, Sed cleans out the file when I overwrite it. I tried to rename files, but I just can't reach the logic of doing this...
Any suggestion would be a lot appreciatted.

Thank you in advance.

Post an example of the original content of the files and the expected output you want.

Hi Franklin,

Thanks for your attention.

this is the code

# Changing the Strings
sed -e s/INICIO/$startframe/g \
-e s/FIM/$endframe/g \
-e s/TEMPOINICIAL/$TEMPO1/g \
-e s/TEMPOFINAL/$TEMPO2/g \
-e s/epXXX/ep${EP}/g \
-e s/scXXX/sc${SC}/g \
-e s/shXXX/sh${SH}/g \
-e s/NAME/${i}/g < ${tmpFolder}filesin_line.txt > ${tmpFolder}filesin_line1.txt
sed '$ r' '${tmpFolder}filesin_line1.txt'' < ${tmpFolder}filesin_line1.txt > ${tmpFolder}filesin_lineNEW.txt
rm ${tmpFolder}filesin_line1.txt
done
exit

-------
filesin_line.txt ( this is the first file that has to be inserted into the next one (filesin_lineNEW.txt ))

I don't know if I'm explaining right. But when the looping happens, sed can't overwrite the file (filesin_lineNEW.txt) and I don't know what do it to make sed add the previous modified file.

Please let me know if explanining well...sorry.
Thanks

It's still not clear to me, do you want to append filesin_line1.txt to filesin_lineNEW.txt?
In that case you can do something like:

Code:

cat filesin_line1.txt >> filesin_lineNEW.txt

If not, clarify your question.

Hi Franklin

I did a small test here outside the script with your line using cat and it seems it worked. Wow! That's great! Sometimes are so many commands that I get confused what to use...
Thanks a lot for your help and your attention Franklin.
