Sublime Text 2: How to delete blank/empty lines

问题:

Let's say I had a text file with the following nine lines:

foo

bar

baz

qux

quux

How can I use Sublime Text 2 to remove all four of the blank/empty lines, leaving only five lines?

回答1:

Select the text

Press:

• Ctrl + H on PC, or
• Command + Alt + F on Mac or
• Click Find->Replace.

Make sure you have selected 'regular expression' by pressing:

• Alt + R on PC or
• Command + Alt + R on Mac or
• Click .* in the Find box.

Find what: ^\n

Replace With: (nothing, leave in blank).

回答2:

The regexp in Hugo's answer is correct when there is no spaces in the line. In case if there are space regexp can be ^\s+$

回答3:

There are also some ST2/ST3 Plugins for such tasks. I do like these two:

• Delete Blank Lines (also available via Package Control)
• Trailing Spaces (also available via Package Control)

The first one has two methods for removing empty/unnecessary lines. One of them called Delete Surplus Blank Lines which is cool. It removes only those lines that are followed by another empty line

回答4:

A Find/Replace solution:

Regex Find:\s+

Replace with: //single space

回答5:

Don't even know how this whole thing works, but I tried ^\s*$ and didn't work (leaving still some empty lines).

This instead ^\s* works for me

{sublime text 3}

回答6:

I had to use:

replace \n^\s*\n with \n

The https://github.com/NicholasBuse/sublime_DeleteBlankLines plugin did nothing at all.

回答7:

Simpler than I thought. Ctrl + A Followed by Ctrl + H Then Select Regular Expression .* . Replace \n\n with \n. Voila!

回答8:

You are looking for this:

^\n|^\s+$

it will not delete the line, if there is content with white space or tabs in front>

e.g.:

these will not be deleted: ...space... abc

...tab... abc

this will:

...space... ...nothing else...

...tab... ...nothing else...

回答9:

Using multiple selections: select one pair of line breaks, then use Quick Find All (Alt+F3), or Quick Add Next (Ctrl+D) repeatedly, to select them all; then hit Enter to replace them with single line breaks.

回答10:

Sublime Text 2 & 3

The Comments of @crates work for me,

Step 1: Simply press on ctrl+H

Step 2: press on RegEX key

Step 3: write this in the Find: ^[\s]*?[\n\r]+

Step 4: replace all

回答11:

Another way, you can use the command line cc.dbl of ConyEdit (a plugin) to delete blank lines or empty lines.

回答12:

There's also "Join lines". If on OSX, select all your text, and press CMD-J a few times, and it will collapse your selection by line, removing the line breaks.

Edit: This approach will leave you with everything on one line, which is not what you asked for.

For those who are curious of sublime text editor, the unofficial-documentation may be interesting!

回答14:

There is a wonderful package (for Sublime 2 & 3) called 'Trimmer' which deletes empty lines. It also does many other useful things.

Refer this: https://packagecontrol.io/packages/Trimmer

回答15:

Using find / replace, try pasting a selection starting at the end of the line above the blank line and ends at the beginning of the line after the blank. This works for a single blank line. You can repeat the process for multiple blank lines as well. CTRL-H, put your selection in the find box and put a single newline in the replace box via copy/paste or other method.

In my case some empty lines contained the unicode character zero width space (U+200b). To rid empty lines, including the ones with this unicode character:

\s\x{200b}|^\s

If ^\n does not work properly ===> try .*[^\w]\n
