tabulate

Align data in columns using heuristics to find suitable column sizes that minimize the amount of wasted space. Useful for files like access logs where some lines have columns that are much larger than than the rest of the lines.

$ cat input.txt aaa bbb ccc a b c aaaaaaaaaaaaaaaaaaaaaaa bb cc aaaaa b ccccc aaa bb ccc aaaa bb cccc aaa bb ccc aaa bb ccc aaaaa b ccccc aaa bb ccc aaa bb ccc aaaaa b ccccc $ tabulate <input.txt aaa bbb ccc a b c aaaaaaaaaaaaaaaaaaaaaaa bb cc aaaaa b ccccc aaa bb ccc aaaa bb cccc aaa bb ccc aaa bb ccc aaaaa b ccccc aaa bb ccc aaa bb ccc aaaaa b ccccc $ tabulate -t <input.txt aaa bbb ccc a b c aaaaaaa… bb cc aaaaa b ccccc aaa bb ccc aaaa bb cccc aaa bb ccc aaa bb ccc aaaaa b ccccc aaa bb ccc aaa bb ccc aaaaa b ccccc

USAGE: tabulate [OPTIONS]

OPTIONS: --column-info Print information about the columns

-c, --compress-cols <RATIO>
        Control how much columns are compressed. Set to 0 to disable column
        compression, i.e. columns are sized to fit the largest value [default:
        1.0]
-d, --delimiter <DELIM>
        Use characters of DELIM as column delimiters [default: " \t"]

-n, --estimate-count <N>
        Estimate column sizes from the first N lines [default: 1000]

-x, --exclude <LIST>
        Select which columns should be excluded from the output. This option
        takes precedence over --include
-h, --help
        Prints help information

-i, --include <LIST>
        Select which columns to include in the output

-s, --strict
        Parse columns as strictly being delimited by a single delimiter

-t, --truncate <LIST>
        Truncate data that does not fit in a column. Takes an optional list of
        columns that should be truncated. If no LIST is given all columns are
        truncated
-V, --version
        Prints version information

LIST should be a comma-separated list of ranges. Each range should be of one of the following forms:

N N'th column, starting at 1 N- from N'th column to end of line N-M from N'th to M'th column -M from first to M'th column ```
