Align columns: Difference between revisions

=== Using <tt>column(1)</tt> ===

Note that the left-justified case can be handled trivially by the <tt>column</tt> command, which ships with modern Linux and macOS systems:

<lang sh>tr '$' ' ' | column -t</lang>

{{Out}}

<pre>Given a text file of many lines, where fields within a line

are delineated by a single 'dollar' character, write a program

that aligns each column of fields by ensuring that words in each

column are separated by at least one space.

Further, allow for each word in a column to be either left

justified, right justified, or center justified within its column.</pre>
