I need to remove several characters from the end of a line, how do I do it? For example, let’s remove two letters from JJohnDoe and leaving JJohnD. Any suggestions?

I needed to remove the first character, so I adapted Alan’s code (by the way, thanks Alan!):

x=JJohnDoe;
echo $x
x=$(echo ${x:1});
echo $x

On a file you could just run:

sed -n ‘s/.$//p’ filename.txt

to print each line in the file without the last character. I don’t see much usage in it though :)

People would rather expect to have something that can apply to any last character. Whether it is an a or any other letter.

This code will do it

x=JohnDoee;
echo $x
x=$(echo $x | rev); x=$(echo ${x:1} | rev);
echo $x

Enjoy
