`Align` is a general-purpose text filter tool that helps vertically align columns in string-separated tables of input text. With whitespace-separated columns, you can often use it without arguments and it'll guess the right thing to do. Otherwise, you can specify arguments to direct how the columns are separated on input and rejoined in the aligned output. For example,
$ head -5 access.log
22.56.17.4 - 04/Dec/2000:04:08:53 GET /pub HTTP/1.0 408 - 23146
hrl.com - 04/Dec/2000:07:17:32 GET /zen HTTP/1.0 404 272 27583
gw.kpmg.ie - 04/Dec/2000:09:37:56 GET / HTTP/1.0 200 8135 658
c1.aici.com - 04/Dec/2000:13:25:00 GET / HTTP/1.1 200 8135 8850
dabs.com - 04/Dec/2000:15:04:29 GET / HTTP/1.1 408 - 12305
$ head -5 access.log | align
22.56.17.4 - 04/Dec/2000:04:08:53 GET /pub HTTP/1.0 408 - 23146
hrl.com - 04/Dec/2000:07:17:32 GET /zen HTTP/1.0 404 272 27583
gw.kpmg.ie - 04/Dec/2000:09:37:56 GET / HTTP/1.0 200 8135 658
c1.aici.com - 04/Dec/2000:13:25:00 GET / HTTP/1.1 200 8135 8850
dabs.com - 04/Dec/2000:15:04:29 GET / HTTP/1.1 408 - 12305
Here, `align` correctly guessed that columns were separated by a single space character and generated an alignment using multiple spaces between columns. Also, the type of alignment within a column can be specified to be "left", "right", "center", "numeric" or "zero-padded numeric".
Also included in this package is `width`, another general-purpose text filter tool that helps you work with the printing width or length of lines of input text. For example, it can print the width, location and/or content for its longest line or lines of input, or for all lines. For example,
% head -5 access.log | width -awnl
63:1:22.56.17.4 - 04/Dec/2000:04:08:53 GET /pub HTTP/1.0 408 - 23146
63:4:c1.aici.com - 04/Dec/2000:13:25:00 GET / HTTP/1.1 200 8135 8850
Running `align -h` and `width -h` will provide complete usage summaries.
---------------------------- INSTALLATION ----------------------------
"align" and "width" are Perl scripts that you should be able to install as-is, ie executable in a directory in your PATH. Edit the first line of the scripts, if necessary, to contain the proper path to your perl executable. Alternately, you can use the supplied Makefile to do all this. Just edit the top of the Makefile to your desires and then run:
make
make install
