This can be handled several ways:

• using qsv:

  1. Starting with qsv v0.42.0, with input, using the --skip_lastlines option (ping @pkptzx)
  2. Alternatively, set QSV_COMMENT_CHAR env var to a character like #, and then have the last line start with that char.

• with sed:
  sed -i '$d' <file>

• with head:
  head --lines=-1
