Occasionally I want to move all lines in a file to the top of that file. :g/PATTERN/m0 almost does what I want, but because :g operates one line at a time in order, it will also reverse the affected lines.
Example:
Consider this file. Say I want to separate lines containing a number and move them to the top of the file. :g/d/m0 does almost what I want (fr4nk, car0l and b0b are moved to the top) — but it reverses the order of the matched lines.
alice
b0b
car0l
dan
eve
fr4nk
Actual output:
fr4nk
car0l
b0b
alice
dan
eve
Desired output:
b0b
car0l
fr4nk
alice
dan
eve
One way of doing what I want is to use :g/PATTERN/m$ (which won’t reverse lines) and then move the lines from the bottom of the file to the top. Is there anything simpler?
