Merging multiple lines to columns with awk, while inserting commas for missing lines
Hello all,
I have a large csv file where there are four types of rows I need to merge into one row per person, where there is a column for each possible code / type of row, even if that code/row isn't there for that person.
In the csv, a person may be listed from one to four times consecutively. Each row in which they are listed has a number of hours and a code (WE, MO, CE, ES) that indicates type of hours
I found a similar thread and a solution to a similar problem. The forum won't let me post links yet, but you can add this to the base URL /shell-programming-and-scripting/208027-merge-multiple-lines-same-file-common-key-using-awk.html to open that thread.
However, the output of that script tacks each of the optional lines on to the end of the first line, but that messes up the csv columns, so that the same data is not in the same place in the merged columns, afterward.
Here is a simplified version of the input data I have, which has a lot of fields per line after these, but where for each person, all fields except for the type-of-hours code, and number of hours are identical between lines the person is listed on:
I need the output, to be in the form
Please let me know how I might get this kind of output from this kind of input using awk. Thanks so much for your help!
Hello,
I have file to work with. It has 5 columns. The first three, altogether, constitutes the position. The 4th column contains some values for downstream analysis and the fifth column contains some values that I want to add to 4th column (only if they happen to be in the same position).

Hello,
I need to insert varying lines (i.e. these lines are an output of another script) between lines starting with certain fields.
An example to make it more clear.
This is the file where I wanna insert lines:

Hi,
1. Each message starts with date
2. There is blank line between each message
3. Each message does not contain same number of lines.
Any help in merging multiple lines in each message to a single line is much appreciated.

INSERT(7) SQL Commands INSERT(7)NAME
INSERT - create new rows in a table
SYNOPSIS
INSERT INTO table [ ( column [, ...] ) ]
{ DEFAULT VALUES | VALUES ( { expression | DEFAULT } [, ...] ) [, ...] | query }
[ RETURNING * | output_expression [ [ AS ] output_name ] [, ...] ]
DESCRIPTION
INSERT inserts new rows into a table. One can insert one or more rows specified by value expressions, or zero or more rows resulting from
a query.
The target column names can be listed in any order. If no list of column names is given at all, the default is all the columns of the table
in their declared order; or the first N column names, if there are only N columns supplied by the VALUES clause or query. The values sup-
plied by the VALUES clause or query are associated with the explicit or implicit column list left-to-right.
Each column not present in the explicit or implicit column list will be filled with a default value, either its declared default value or
null if there is none.
If the expression for any column is not of the correct data type, automatic type conversion will be attempted.
The optional RETURNING clause causes INSERT to compute and return value(s) based on each row actually inserted. This is primarily useful
for obtaining values that were supplied by defaults, such as a serial sequence number. However, any expression using the table's columns is
allowed. The syntax of the RETURNING list is identical to that of the output list of SELECT.
You must have INSERT privilege on a table in order to insert into it. If a column list is specified, you only need INSERT privilege on the
listed columns. Use of the RETURNING clause requires SELECT privilege on all columns mentioned in RETURNING. If you use the query clause
to insert rows from a query, you of course need to have SELECT privilege on any table or column used in the query.
PARAMETERS
table The name (optionally schema-qualified) of an existing table.
column The name of a column in table. The column name can be qualified with a subfield name or array subscript, if needed. (Inserting into
only some fields of a composite column leaves the other fields null.)
DEFAULT VALUES
All columns will be filled with their default values.
expression
An expression or value to assign to the corresponding column.
DEFAULT
The corresponding column will be filled with its default value.
query A query (SELECT statement) that supplies the rows to be inserted. Refer to the SELECT [select(7)] statement for a description of the
syntax.
output_expression
An expression to be computed and returned by the INSERT command after each row is inserted. The expression can use any column names
of the table. Write * to return all columns of the inserted row(s).
output_name
A name to use for a returned column.
OUTPUTS
On successful completion, an INSERT command returns a command tag of the form
INSERT oid count
The count is the number of rows inserted. If count is exactly one, and the target table has OIDs, then oid is the OID assigned to the
inserted row. Otherwise oid is zero.
If the INSERT command contains a RETURNING clause, the result will be similar to that of a SELECT statement containing the columns and val-
ues defined in the RETURNING list, computed over the row(s) inserted by the command.
EXAMPLES
Insert a single row into table films:
INSERT INTO films VALUES
('UA502', 'Bananas', 105, '1971-07-13', 'Comedy', '82 minutes');
In this example, the len column is omitted and therefore it will have the default value:
INSERT INTO films (code, title, did, date_prod, kind)
VALUES ('T_601', 'Yojimbo', 106, '1961-06-16', 'Drama');
This example uses the DEFAULT clause for the date columns rather than specifying a value:
INSERT INTO films VALUES
('UA502', 'Bananas', 105, DEFAULT, 'Comedy', '82 minutes');
INSERT INTO films (code, title, did, date_prod, kind)
VALUES ('T_601', 'Yojimbo', 106, DEFAULT, 'Drama');
To insert a row consisting entirely of default values:
INSERT INTO films DEFAULT VALUES;
To insert multiple rows using the multirow VALUES syntax:
INSERT INTO films (code, title, did, date_prod, kind) VALUES
('B6717', 'Tampopo', 110, '1985-02-10', 'Comedy'),
('HG120', 'The Dinner Game', 140, DEFAULT, 'Comedy');
This example inserts some rows into table films from a table tmp_films with the same column layout as films:
INSERT INTO films SELECT * FROM tmp_films WHERE date_prod < '2004-05-07';
This example inserts into array columns:
-- Create an empty 3x3 gameboard for noughts-and-crosses
INSERT INTO tictactoe (game, board[1:3][1:3])
VALUES (1, '{{" "," "," "},{" "," "," "},{" "," "," "}}');
-- The subscripts in the above example aren't really needed
INSERT INTO tictactoe (game, board)
VALUES (2, '{{X," "," "},{" ",O," "},{" ",X," "}}');
Insert a single row into table distributors, returning the sequence number generated by the DEFAULT clause:
INSERT INTO distributors (did, dname) VALUES (DEFAULT, 'XYZ Widgets')
RETURNING did;
COMPATIBILITY
INSERT conforms to the SQL standard, except that the RETURNING clause is a PostgreSQL extension. Also, the case in which a column name list
is omitted, but not all the columns are filled from the VALUES clause or query, is disallowed by the standard.
Possible limitations of the query clause are documented under SELECT [select(7)].
