Script to check a file and replace some of the contents
Hi
I have a file that looks like this:
What i am aiming to do is with a script and an input value of a number between 0-3 is to change the elephant to dog so running the script with ./script.sh 2 will change the file so it looks like this
So far i have this but it fails on "if [ $i -eq $CHANGE ]; then"
I am not sure how to test if the line with Line 2 actually contains the value 2 in it, i'm guessing grep would be handy but i'm not really a scripter so I am a bit stuck. When the correct line with Line x is found then set NEXTLINE and go to the next line thru the for statement and then use sed to change the value.
I have had the following sugguested
but don't understand how to use it.
Any help would be much appreciated.
Note: I have change the value of the data in the inputfile to something generic.
