Edit a File When You Are Viewing It Using more / less Command Pager
can use less
or more pagers to view a file. How do I start an editor
(such as vi or other text editor) to edit the current file without leaving the less or more
|Estimated completion time||N/A|
You can always start up an editor immediately to edit the current file being viewed. This will save some time and command typing. The editor is taken from the environment variable VISUAL if defined, or EDITOR if VISUAL is not defined, or defaults to "vi" if neither VISUAL nor EDITOR is defined. I suggest you define your EDITOR first, enter:
$ export EDITOR=vim
$ echo 'export EDITOR=vim' >> ~/.bash_profile
Open any text file using more or less pager, type:
$ less myfile.txt
$ more ~/some.conf
To edit a file, hit v
key from keyboard. This will start up an editor at current line and file.
