Unix Adding Text to corresponding lines...

[thaiZilla]

grep $USER xx >> filenorman.thai

i used the above command to gain a searched list for a user and put it into a file called filenorman.thai , the following is a bit of its contents...

USER=norman.tha i
MAIL=/var/spool/mail/norman.thai
PWD=/home/norman.thai
HOME=/home/norman.thai

My question is, how do i add the corresponding line number as well as a bracket to make the text look like this:-

1)USER=norman.t hai
2)MAIL=/var/spool/mail/norman.thai
3)PWD=/home/norman.thai
4)HOME=/home/norman.thai

awk '$0=++c")"$0' filenorman.thai>_tmp&&mv _tmp filenorman.thai

[thaiZilla]

awk '$0=++c")"$0' filenorman.thai>_tmp&&mv _tmp filenorman.thai

Is there a method without awk cos i'm learning from the basics and i've used tmp files before but i want a way without using a tmp file. Thanks

It uses temporary file implicitly though ...

(rm file&&nl -s\) -w1>file)<file

i was told to look into loops. I'm new tho i'll have a crack at what you put in.

Hey thanks for your time, both codes you provided for me work, i vaguely understand the last one...i just don't understand why my tutorials would ask me to look at loops.

If you have any time could you explain the nl -s\ command and w1 in your coding - (rm file&&nl -s\) -w1>file)<file

Thanks again you have been helpful

Sure,
man nl says:

nl - number lines of files
[...]
-s, --number-separator=STRIN G
add STRING after (possible) line number
[...]
-w, --number-width=NUMBER
use NUMBER columns for line numbers



The -s option let you specify the character after the number:
")" in our case, we need to escape it,
because it's special for the shell, the -w option let you specify
the number of columns for the line numbers, try the command
without it to see the difference.
