What is a LESSHST file?
A LESSHST file is a search history file created by less, a terminal pager program for PCs. It contains a record of the search commands a user has entered in less. Less uses its LESSHST file to remember the previous text searches a user has performed.
More Information
Less is a program that allows users to read (but not edit) text files in a terminal window. It is included with many Unix distributions (including macOS) and also available for Windows.
While reading a text file in less, users can search for text within the document. To do so, they use the program's search commands (by pressing the / or ? keys) and then enter the text for which they want to search.
By default, less stores a record of a user's text searches in a LESSHST file. This allows the user to both view all the searches they've performed and quickly resume their last-conducted search (by pressing the n or N key). Less typically stores its LESSHST file in the user's home directory.
NOTE: To stop less from creating a LESSHST file, set the LESSHISTFILE variable to -.
How to open a LESSHST file
You can open a LESSHST file with Vim, Apple TextEdit, or Microsoft Notepad, to view or edit the less search history it contains.
