The less command is a Linux terminal pager which shows a file's content one screen at a time. Useful when dealing with a large text file because it doesn't load the entire file but accesses it page by page, resulting in fast loading speeds.
less [options] file_path
Some popular option flags include:
-E less automatically exits upon reaching the end of file.
-f Forces less to open non-regular files (a directory or a device-special file).
-F Exit less if the entire file can be displayed on the first screen.
-g Highlights the string last found using search. By default, less highlights all strings matching the last search command.
-G Removes all highlights from strings found using search.
For a complete list of options, refer to the less help file by running:
less --help
- Open a Text File
less /etc/updatedb.conf
- Show Line Numbers
less -N /etc/init/mysql.conf
- Open File with Pattern Search
less -pERROR /etc/init/mysql.conf
- Remove Multiple Blank Lines
