命令删除vim中的所有空格

Question

I want to be able to remove all the white spaces in my txt file using vim

update reg04_rpt_animreg set birthdate = '      2016-01-21       ' where animalid = '   TZN000192803889  ';
update reg04_rpt_animreg set birthdate = '      2015-07-05       ' where animalid = '   TZN000192803890  ';
update reg04_rpt_animreg set birthdate = '      2011-12-12       ' where animalid = '   TZN000192803891  ';
update reg04_rpt_animreg set birthdate = '      2013-05-05       ' where animalid = '   TZN000192803893  ';
update reg04_rpt_animreg set birthdate = '      2013-04-02       ' where animalid = '   TZN000192803894  ';
update reg04_rpt_animreg set birthdate = '      2015-05-16       ' where animalid = '   TZN000192803895  ';

I have used the following command with vim but havent gotten my expected output

:g/^\s*$/d

Answer 1

I think you're looking for the s command; :g/<regexp>/d deletes the whole line which matches <regexp> .

:%s/\s//g

This replaces all space-type characters ( \\s ) globally ( g ).

Answer 2

如果您只想在单引号内修剪空格，则应该可以：

:%s/= '\zs\s*\(\S*\)\s*'/\1'/g
