Placing numbers 1

[Guest_imported]

Hi,

I've created a script that prints an output like:

@Participants: Tom
@ID: Tom
@Participants: Cathy, Peter
@ID: Cathy
@ID: Peter
@Participants: Bart, Karen, Lizzy
@ID: Bart
@ID: Karen
@ID: Lizzy

I want to add numbers before a line that matches @Participants so that my output becomes:

1. @Participants: Tom
@ID: Tom
2. @Participants: Cathy, Peter
@ID: Cathy
@ID: Peter
3. @Participants: Bart, Karen, Lizzy
@ID: Bart
@ID: Karen
@ID: Lizzy

Does anyone know how I should do this? Thanks!

Hi Univ,

You can prepend the string like this:

awk '{

if ( $0 ~ /Participants/ ) {
$1 = ++i". "$0
print
} else {
$1 = " "$0
print
}

}' infile > outfile

Hope this helps

If the poster wanted to sequentially number the "Participants" lines in the file, there is a bug in the proposed solution:

{

if ( $0 ~ /Participants/ ) {
$0 = ++i"."$0
print
} else {
$0 = " "$0
print
}
}

If the poster wanted to count the number of corresponding items for a given "Participants" line, the solution might be:

{

if ( $0 ~ /Participants/ ) {
$0 = split(substr($0, index($0, ":&quot+1), tmp, ",&quot"."$0
print
}
else {
$0 = " "$0
print
}
}

Input:

@Participants: Tom
@ID: Tom
@Participants: Bart, Karen, Lizzy
@ID: Bart
@ID: Karen
@ID: Lizzy
@Participants: Cathy, Peter
@ID: Cathy
@ID: Peter

Output:

1.@Participants: Tom
@ID: Tom
3.@Participants: Bart, Karen, Lizzy
@ID: Bart
@ID: Karen
@ID: Lizzy
2.@Participants: Cathy, Peter
@ID: Cathy
@ID: Peter
