## chomp

```

usage: chomp [-h] [FLAGS]

Receives input from STDIN

Removes extra whitespace characters from the beginning/end of lines

Removes lines which have just whitespace (no content)

Flags:

  -max-capacity int

    	Maximum capacity for each line in kilobytes. Can also set through CHOMP_MAX_CAPACITY environment variable. (default 64)

```

This is essentially a portable (and 3x faster):

```

sed -E -e 's/^\s*//; s/\s*$//; /^\s*$/d'

```

[I use this in scripts](https://gist.github.com/seanbreckenridge/02bf00bc50b3ad6a35088fb75e41e9e6) when trying to remove spaces from user input/command output. Its also often helpful when data wrangling, to be able to quickly ignore lines/spaces I'm not interested in.
