tcat
: Table Concatenater
tcat
is a tool for concatenating tables one after the other.
If you have two tables T1 and T2 which contain similar columns, and you
want to treat them as a single table, you can use tcat
to produce a new table whose metadata (row headings etc) comes from T1
and whose data consists of all the rows of T1 followed by all the rows
of T2. This will only work if the columns of the two tables to be
joined have the same or compatible types in the same order;
if they do not, you must use the icmd
parameters to
preprocess the input tables so that the column sequences are compatible.
In the current release of STILTS, tcat
is rather
rudimentary: you can only join two tables at once, you must arrange
for the columns to be in the right order, and you may end up with
an unhelpful error if the columns in matching positions are not of
compatible types. Behaviour will be improved in a future release.
