Add single quotes in string
Hi All, I love this site, it helps newbie people like me and I appreciate everyone's help!
Here is my questions.
I am trying to concatenate a single quote into a character/string from a text file for each line (lets say ABC should look like 'ABC').
I tried to use awk print command to do this, but it always gives me syntax error (i followed the awk document as it says).
Is there a unix short cut command to do this ?
thanks a lot!
