Shell Programming and Scripting

I am trying to edit a file in shell script using sed. I need to get the input from command line
suppose

script.sh

Code:

sed"/s place=/place=california/g" > /root/user/mark.txt
echo " place changed "

the above code searches for string place in the file mark.txt and replaces with place= california.

Now I need california to be entered manually when it runs the script and return back to the next commands in the script

supose when I run the script it should run as follows

enter place = california (user should give the input)

This? Note that if you alread have place=Arizona and that you enter California, it will output place=CaliforniaArizona.

above code mix the html code and wrong way to use s function in sed. Here is the correction.

Code:

VALUE="california"      # or use command read as above 
sed "s/place=/place=$VALUE/g" /root/user/mark.txt  > other_output.txt
echo " place changed to $VALUE"

I think the code send by frans is fine.But can you please test it and resend. its not working

Fine? I don't think so.

Are you really test frans's code? I don't think you can get right result.

I think it won't
if you already have place=Arizona and you enter California, it will output place=CaliforniaArizona.
How does the file look like? if place=<PLACE> is alone on its line, first you don't need the g (global) option of sed substitution, second you can write

Code:

sed "s/place=.*/place=$VALUE/"

You should post a sample of your data file.
