I have learned from this Stack Overflow question that it is possible to use
vim to comment out a specified range of line numbers. For example, suppose I have the following bash script:
#!/bin/bash This is my very very great script
Now suppose that I want to comment out line numbers 6 through 8 (which contain the words
great) using the
# comment character. In
vim, I can simply type
:6,8s/^/# to obtain the following:
#!/bin/bash This is my #very #very #great script
which comments out lines 6 through 8.
My question is, is it possible to type a similar one liner that will remove the
# comment character from lines 6 through 8 (but not any other commented lines in the file)?
Having said this, I realize that there is some debate about whether I am actually using
vim. In practice, I open a file
script.sh with the command
vi script.sh. Also, when I type the command
which vi, I obtain
/usr/bin/vi. Nevertheless, when I simply type
vi and press Enter, I obtain this:
~ VIM - Vi IMproved ~ ~ version 7.2.330 ~ by Bram Moolenaar et al. ~ Vim is open source and freely distributable ~ ~ Sponsor Vim development! ~ type :help sponsor<Enter> for information ~ ~ type :q<Enter> to exit ~ type :help<Enter> or <F1> for on-line help ~ type :help version7<Enter> for version info
which seems to suggest that I'm actually using
vim. I am accessing a remote Ubuntu Linux cluster using SSH from my PC. I am not using a Ubuntu Linux GUI.
