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 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.
