generating line numbers

hello All

Do anybody know how to generat number line
that is puting the number of lines at the begining of a new line, with d bracket by the side
say
1)
2)
3)

any help would be nice

The "Similar Threads" at the bottom of this page would be a good place to start. (Too bad the forums don't display that until you have posted your question.)

I kjnow the cat -n works but puting the ) after each number line is complicated bit
# 4  
Code:
cat -n "$file" | sed -e 's/^ *[1-9][0-9]*/&)/'

The regular expression matches start of line, zero or more spaces, and a nonzero positive integer, and sed replaces any match with whatever matched (& is the "magic" character which does this) and a right parenthesis.

Actually this is probably easier in awk.

Code:
awk '{ print NR ") " $0 }' "$file"

NR is the current line number and $0 is the input line.
