Shell Programming and Scripting

It will create new file "runx"

I want to see the result at line number 211 in run file:
main file to edit "run": *include idemo.axe;btxt=demotxt

i want to change demotxt to "Power Tools or Accessories" and again I have few more things to pass,

after this I am using file run.do which will update run file as runx with the help of file source where i am passing all the parameters

Please let me know if you need anything else...

The problem throughout this thread is the single quote characters. You cannot nest single quote characters. They are treated in pairs. In fact the middle two single quotes are not required in any of the sed commands posted.

sed 's/brdtxt/'$3'/g'
Thus the substitition parameter $3 is left outside of the scope of either pair of quotes. It sort of works until there are space characters in $3 - then the sed command errors.

Code:

Consider these simplified examples:

echo "brdtxt"|sed 's/brdtxt/'Banana'/g'
Banana

echo "brdtxt"|sed 's/brdtxt/'Power Tools or Accessories'/g'
sed: Function s/brdtxt/Power cannot be parsed.


Now we remove the middle two single quote characters and it starts working.

echo "brdtxt"|sed 's/brdtxt/Power Tools or Accessories/g'
Power Tools or Accessories

echo "brdtxt"|sed 's/brdtxt/"Power Tools or Accessories"/g'
"Power Tools or Accessories"

Thnaks for letting me know the system present at your end, I will keep this in mind from next time.

Thanks Methyl! But I want to pass about 50 brand text in this file and hence was trying to pass them from outside, if it is not posible to pass a sentence with SHELL then I will have to use the method you have suggested but it really will not shorten the script which i want to.

Thanks & Regards,

That was only an example to justify removing the inner pair of single quotes.
However once we are inside a shell script we need to lose the single quotes completely or they will stop the substitution of $3.

Code:

sed 's/brdtxt/'$3'/g'
Change to:
sed -e "s/brdtxt/$3/g"

Obviously the same error is in all the "sed" statements but it only goes wrong of the parameter contains space characters.

Thanks Methyl, it's now working, thanks very much!
