Hi,

I wrote a script, but it's not working. Please advise. I want to add the text at the end of the file. Should I use sed or awk. Not sure any thing is fine with me.

#!/usr/bin/ksh
DATE=`/usr/bin/date '+%m%d%y'` 
cp -p /etc/inittab /etc/inittab_$DATE
sed's/$/"hobbit:234:once:/etc/rc.hobbit start"/g' /etc/inittab

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

if you want to add text to the end of a file why not use ">>" to do this?

echo "hobbit:234:once:/etc/rc.hobbit start" >> /etc/inittab

you want to add at the end of the file or the at the end of last line of the file??

This is what I did and it's working fine but curious to learn if I can do this in a different ways?

#!/usr/bin/ksh
DATE=`/usr/bin/date '+%m%d%y'` 
cp -p /etc/inittab /etc/inittab_$DATE
cat "hobbit:234:once:/etc/rc.hobbit start"  >>  /etc/inittab

as allways there are more than one way to do things in a script. the art is to know which is best for your case .
tools you should look at are maybe sed/ed/awk. but make sure to know the smaller and faster tools like grep/cut/>/>> and so on.
