yargs

yargs aims to be the xargs equivalent to tabular input. It borrows from awk the its ability to work on columns of text and allows for arbitrary commands to be applied per column in a similar way to xargs.

The columns are called fields. The command to execute on each field is called an y-arg.

Usage

passing column yargs as fields

foo_cmd | yargs --field-1='basename {}'  --field-2="awk { print $1 }"
foo_cmd | yargs -f1 'basename {}' -f2 'awk { print $1 }'

Passing yargs as positional arguments

foo_cmd | yargs 'basename {}' 'awk { print $2 }'

skipping fields

foo_cmd | yargs 'basename {}' - 'awk { print $2 }'
# keeps the second field unchanged

Example

input:

         field #1                 field #2
|--------------------------|   |--------------|
/long/path/to/some/ebook.pdf   | Title Of Ebook
                                 ____
                                   |
example usage:                     | y-arg
--------------                     |                     
                      ----------------                       
yargs 'basename {}' "awk { print $1 }"
                                                

#OR
yargs -f1 'basename {}' -f2 'awk { print $1 }'

would output: ebook.pdf | Title

use colon as delimiter

yargs -d':' -f1 '...'
