I have two files. One being a schema, and the other a list of data. The schema looks like:
line_name: shot_edit: channel edit: cable_edit and repeats regularly for the number of lines that I have.
The other file is a list of line names and goes:
name1 name2 name3 I'd like to copy all the line names into just after the line_name field, but I'm really not all that good with awk. Could anyone give me some pointers?
Both of these commands give the following output
sed '/line_name/ r linenames' schema awk '{print} /line_name/ {while (getline < "linenames") print}' schema line_name: name1 name2 name3 shot_edit: channel edit: cable_edit This command insert each line of the second file (linenames) after each first line in the file schema
awk '{print} /line_name/ { getline < "linenames" ; print}' schema with this output
line_name: name1 shot_edit: channel edit: cable_edit line_name: name2 shot_edit: channel edit: cable_edit .... This command instead
awk '{print} /line_name/ { getline < "linenames" ; print}' schema | sed ':a;N;$!ba;s/line_name:\n/line_name: /g' Insert the name just after the tag line_name:
line_name: name1 shot_edit: channel edit: cable_edit line_name: name2 shot_edit: channel edit: cable_edit line_name: name3 ... If you want to insert in the same line with line_name:
$ awk '/line_name/{getline name < "linenames";$0 = $0" "name}1' schema line_name: name1 shot_edit: channel edit: cable_edit line_name: name2 shot_edit: channel edit: cable_edit line_name: name3 shot_edit: channel edit: cable_edit 
line_name: name1 name2 name3or do you want something more complex? How many lines more or less? Doescable_editnot have a:? What are the names? Do they contain spaces?
